#SpaceSnap: Hubble Space Telescope’s Photo of the Heart of the Flame Nebula – iTech Post
Posted: March 26, 2022 at 6:33 am
The Hubble's Space Telescope captured a spectacular image of a Flame Nebula also known as NGC 2024. Located in the constellation Orion, NGC 2024 is a large star-forming region and is approximately 1,400 light-years away from Earth.
The Flame Nebula recently captured by the Hubble Space Telescope is particularly part of the Orion Molecular Cloud Complex, or popularly known as Orion Complex.
The Orion complex is one of the most active of those visible in the night sky located in the Milky Way.
As reported by NASA, the Flame Nebula captured is in the area where nebulae such as the Horsehead Nebula and the Orion Nebula are also located.
(Photo : NASA, ESA, and N. Da Rio (University of Virginia); Processing: Gladys Kober (NASA/Catholic University of America))NASAs Hubble Space Telescope captures another Flame Nebula.
This image captured by the Hubble Space Telescope focuses on the dark, dusty heart of the nebula, which contains a star cluster that is largely hidden from view by the surrounding dust.
The bright star Alnitak, the easternmost star in the Belt of Orion, is close by (but not visible in this image) and is the brightest star in the constellation. The hydrogen gas in the Flame Nebula is ionized as a result of the radiation from Alnitak.
In order for the gas to transition from a higher-energy state to a lower-energy state, it must first emit energy in the form of light. This causes the visible glow behind the swirling wisps of dust to appear.
Nebulas are large clouds of dust and gas that form in space. Several nebulae are formed by the explosion of a dying star, such as a supernova, which releases gas and dust into space. Other nebulae are regions where new stars are beginning to form, as opposed to the central nebula. Some nebulae are also referred to as "star nurseries" as a result of this phenomenon.
Nebulae are composed of dust and gasses, the majority of which are hydrogen and helium. Although the dust and gasses in a nebula are widely dispersed, gravity has the ability to gradually pull clumps of dust and gas together over time. Since these clumps grow in size, the gravitational pull of the clumps becomes stronger and stronger.
According to NASA's Space Place:"The clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star."

NASA'sHubble Space Telescopehas taken numerous images of faraway nebulae. This extremely powerful microscope has been used by astronomers "to measure the mass of stars in the cluster as they search for brown dwarfs, a type of dim object that's too hot and massive to be classified as a planet but also too small and cool to shine like a star."
The Hubble Space Telescope is a large, space-based observatory named in honor of the trailblazing astronomer Edwin Hubble.
The Hubble Telescope has the scientific ability to have a crystal-clear view of the universe. It is located far above rain clouds, light pollution, and atmospheric distortions. Researchers have made use of the Hubble Space Telescope to observe some of the most distant stars and galaxies that have ever been observed, as well as the planets of our solar system.
When the Hubble Space Telescopewas launched into orbit around the Earth, it became the world's first astronomical observatory to be equipped with the capability of recording images in wavelengths of light ranging from ultraviolet to near-infrared.

Junk DNA may rein in memories tied to fear – Futurity: Research News

A piece of junk DNA could be the key to extinguishing fear-related memories for people struggling with post-traumatic stress disorder and phobia, according to a new study.
Researchers discovered the new gene while investigating how the genome responds to traumatic experiences.
Its like harnessing the power of the Hubble Telescope to peer into the unknown of the brain.
Until recently, scientists thought the majority of our genes were made up of junk DNA, which essentially didnt do anything, says Timothy Bredy, associate professor at the University of Queenslands Brain Institute.
But when researchers began to explore these regions, they realized that most of the genome is active and transcribed.
Using a powerful new sequencing approach, Bredys team identified 433 long noncoding RNAs from relatively unknown regions of the human genome.
The technology is a really interesting way to zero in on sites within the genome that would otherwise be masked, Bredy says. Its like harnessing the power of the Hubble Telescope to peer into the unknown of the brain.
A new gene, which the researchers labeled ADRAM, was found to not only act as a scaffold for molecules inside the cell, but also helped coordinate the formation of fear-extinction memory.
Until now, there have been no studies devoted to understanding these genes, or how they might influence brain function in the context of learning and memory.
Our findings suggest that long noncoding RNAs provide a bridge, linking dynamic environmental signals with the mechanisms that control the way our brains respond to fear, Bredy says.
With this new understanding of gene activity, we can now work towards developing tools to selectively target long noncoding RNAs in the brain that directly modify memory, and hopefully, develop a new therapy for PTSD and phobia.
The study appears in Cell Reports.
The Brain & Behaviour Research Foundation (NARSAD), the National Institutes of Health, the Australian Research Council, and the Westpac Bicentennial Foundation funded the work.

Rithy Panh on the joy he finds in mentoring rising filmmakers – Screen International
Posted: March 18, 2022 at 7:37 pm
Oscar-nominated Cambodian-French director Rithy Panh has a vivid memory of how he first encountered filmmaking. As a young man, Panh had been studying carpentry in Paris and dabbling in painting. He had moved to France after his family had suffered horrific experiences under the Khmer Rouge in Cambodia.
One of his friends was making a short film inspired by Alfred Hitchcock and had asked Panh to give him a hand. This was just for fun. Panh helped with the lighting and other chores. Then, one day, the friends father gave him three cartridges of three minute each, contact chrome Super 8.
Panh used the film to make a short comedy (very funny), still his only foray into that genre. He went on to study at renowned French film school, IDHEC. At the time, most of the young filmmakers in my generation, in my school, liked fiction films - the Nouvelle Vague, Almodovar, John Cassavetes or John Ford.
But Panhs tastes were different. He was drawn to the work of thee Russian directors Andrei Tarkovsky and Alexei Guerman and to the Neo-Realists. And I very much liked documentary films.
He was one of the few students who wanted to make documentary. Even today, when you go to the Oscars, you have one award for documentary film and for fiction film you have best director, best film, best lighting etcits like cinema doesnt want us to be part of the family.
Since those film school days, Panh has achieved huge success in a series of documentaries which have dealt with the Khmer Rouge genocide and its aftermath. His very first feature documentary Site 2 in 1989, about a refugee camp on the Cambodian-Thai border, won an award at the Festival of Amiens. He also picked the top prize for Un Certain Regard in Cannes with The Missing Picture in 2013, which secured an Oscar nomination.
For several years, Panh has combined his own filmmaking with his work teaching in Cambodia and at the DFIs documentary lab in Doha.
Its something that keeps me close to the young generation, the director says of his mentoring work. I always take some time in my life to train young people who come from different countriesits very important for our society now, especially when you are from a country like Cambodia, where you come across many tragedies, you need art to rebuild your identity and social cohesion. Its the same when I move abroad to teach. At the Doha Film Institute, for example, many people come from Palestine or come from Yemen.
Panhs approach with rising filmmakers is straightforward. He encourages them to learn film grammar and to use technique but the most important thing is to make them feel free.
He sends the students copious amounts of material to study: paintings (from Jackson Pollock to Goya) and photographs as well as films.
Most of the time, the people have talent but not yet a cultural background, especially people from poor countries, he says. They dont have the possibility to watch films or go to museums or to read books etc. We need to give them the [cultural] background, the cinematographic background. Afterwards, we can talk about the project.
Panhs most recent feature, Everything Will Be OK, screened in competition at the Berlinale earlier this year, winning a Silver Bear. It is a documentary about the rise of totalitarianism which uses models of animals, archive footage and references to cinema history. As he said in his Berlin press conference, democracy today is really fragile, more fragile than ever before. I was wondering about the role of cinema in these times. What can we do? What should we do?
He acknowledges film cant change the world. Instead, he believes it serves a similar purpose to poetry where you read a few lines and it changes your day. You feel betteror even when you feel more sad, its OK because it reveals something in you.
And now Panh is waiting for his next project to reveal itself. I want to make a retreat to the forest to find some silence.
He admits he is spending many hours on the NASA website looking at images of the galaxy and pictures taken through the Hubble telescope. We are only dust. Maybe I need to feel myself as nothingmaybe it is a good way for me to be normal.

Hubble telescope was at the perfect angle to capture this nearly impossible shot of two ‘dancing galaxies’ – Space.com
Posted: March 15, 2022 at 6:24 am
Deep within the Andromeda constellation, some 320 million light-years away, two galaxies are consumed by a gravitationally bound dance, and the Hubble Space Telescope has just photographed the action in extraordinary three-dimensional detail.
The two dancers are the smaller polar-ring galaxy IC 1559 (top) and the larger spiral galaxy NGC 169 (bottom). Collectively, they are known as Arp 282, as designated in Halton Arp's Atlas of Peculiar Galaxies.
It's not unusual for galaxies to interact gravitationally. "Astronomers now accept that an important aspect of how galaxies evolve is the way they interact with one another," NASA officials wrote in a statement. "Galaxies can merge, collide, or brush past one another each interaction significantly affecting their shapes and structures."
Related: The best Hubble Space Telescope images of all time!
It is difficult, however, to photograph such an interaction in a way that clearly demonstrates its movement within three-dimensional space. In the case of Arp 282, Hubble was at the perfect angle to capture the strands of stars, dust and gas being pulled by tidal forces from one system to the other.
If Arp 282 were tilted at a different angle, the telescope might never have been able to image the dance so clearly. Imagine looking at this scene through the bottom of NGC 169, for example it'd be unlikely to see the distortion of the two galaxies as crisply.
It's also fortunate that the instrument took this image in visible light. Both IC 1559 and NGC 169 have active galactic nuclei (AGN), meaning their cores are "monumentally energetic," per NASA. In other words, they have supermassive black holes expelling vast quantities of energy in the full range of the electromagnetic spectrum.
"If the image revealed the full emission of both AGNs," NASA officials wrote, "their brilliance would obscure the beautifully detailed tidal interactions we see in this image."

A poet’s ode to the Hubble Telescope and to her father, who helped to build it – Aeon
Posted: at 6:24 am
At the moment, astronomers and astrophiles across the globe are just beginning to receive some of the first highly anticipated images from the James Webb Space Telescope. The short film My God, Its Full of Stars invites viewers to celebrate its predecessor in peering deeper into the cosmos than humanity ever has before the Hubble Space Telescope as well as some of the human stories behind it. Created to accompany an essay by Maria Popova as part of the The Marginalians Universe in Verse series, the animation adapts a poem by the former US Poet Laureate Tracy K Smith, whose father worked on the Hubble as one of NASAs first Black engineers. Pairing Smiths words with meticulously crafted visuals from the Brazilian animation director Daniel Brunson, the piece is a wondrous ode to our desire to know the Universe. Reflecting on the project in her essay, Popova writes:

Mysterious globular clusters could unlock the secrets of galaxy formation – Space.com
Posted: at 6:24 am
Paul M. Sutteris an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of "Ask a Spaceman" and "Space Radio," and author of "How to Die in Space."
Globular clusters are like astronomical coelacanths mysterious living fossils. These densely packed collections of ancient stars may hold the ultimate secrets to the formation of galaxies.
On a clear, dark night, you can see the globular cluster Omega Centauri with the naked eye. It looks like a midrange, typical star, so much so that it's been listed in star catalogs since antiquity. But once astronomers looked at the object through a telescope, they discovered that it wasn't a single star at all but rather one of the largest globular clusters a small, round, dense collection of millions of stars.
That roundness is what separates globular clusters from other kinds of star clusters (and gives them their name, from the Latin for "small sphere"). They are large enough and contain enough stars that there's enough gravity to pull them into spherical shapes.
And that's about the last thing that makes sense about globular clusters.
Related: Vibrant globular cluster sparkles in new Hubble telescope photo
Globular clusters are freakishly old. Of the approximately 150 of them within the Milky Way, the very youngest are no less than 8 billion years old, while the oldest are almost 12 billion years old. They haven't had new rounds of star formation in billions of years, so what remains within them are either remnants (white dwarfs, black holes, etc.) or small, dim, red stars. Whatever caused them to form happened a long, long time ago, and they simply haven't changed much in all those eons since.
In fact, Omega Centauri is one of the oldest things you can see with the naked eye. When the solar system formed, that globular cluster was already fantastically ancient.
The globular clusters are incredibly dense, too. In the deepest parts of their cores, stars cram together up to a thousand times more densely than in the solar neighborhood. They are so tightly packed that planets are almost impossible; there are just too many close calls and near misses for a planetary system to survive long.
In the past few decades, astronomers have noticed that there are very roughly two distinct kinds of globular clusters: young ones and old ones.
Of course, "young" here is a relative term. These younger ones tend to be 8 billion to 10 billion years old. They also tend to hang out closer to the central bulge of the Milky Way and have far more metals than the other globular clusters. In astronomy jargon, "metals" means any element other than hydrogen and helium. Those heavier elements are forged inside stars through nuclear fusion, and in a normal galaxy, continued rounds of star formation and star destruction continually enrich the galaxies. But because all of these globular clusters were born at roughly the same time, with no new star formation since then, the presence of metals means that the globular clusters had to form from an already-metal-rich environment.
The other, older globular clusters are more in the 10 billion to 12 billion-year-old range. These are far more common; about two-thirds of the globular clusters in the Milky Way are from this population. They tend to be farther from the galactic center, have all sorts of random orbits and be almost metal-free.
Astronomers suspect that the young globular clusters formed with the Milky Way itself 8 billion to 10 billion years ago, while the older ones formed before our galaxy even got going. Those globular clusters probably formed with small, dwarf galaxies that got demolished by the Milky Way. The dwarf galaxies were torn apart, but the small, dense globular clusters managed to survive to the present day (nevertheless forced to orbit the same galaxy that destroyed their parents).
OK, great; we have two kinds of globular clusters. But how did they form in the first place?
The biggest clue to the origins of globular clusters is that they have no dark matter. Measurements of their mass using different techniques (adding up all the sources of light, calculating the gravity needed to keep them round, and so on) all add up to the same number, with no need for a hidden, unseen component. This means that globular clusters in the present day are entirely unlike galaxies. It's a little challenging to come up with a definition of "galaxy," but since almost all galaxies are made of at least 80% dark matter, you must include that fact somehow.
Because globular clusters lack dark matter, it means we can't just treat them as minigalaxies at least, in the present day. It's possible that dark matter played a role in forming globular clusters, the same way it did for galaxy formation, just on a much smaller scale. But perhaps the dark matter in the globular clusters dispersed through interactions with parent galaxies, leaving behind the clump of dead and decaying stars.
Or maybe dark matter never played a role. Maybe instead of being failed galaxies, globular clusters are super-successful star clusters. Take the same process that forms any other cluster (a large cloud of gas and dust collapsing and splintering into a shower of stars) and ramp it up to 11, and you get hundreds of thousands or millions of stars in a single go. That intense flash of star formation shoved away all the remaining gas, leaving the globular cluster intact but functionally dead.
To date, astronomers aren't exactly sure which scenario is more likely. Either way, globular clusters are intriguing because they are so obviously linked to galaxy formation and astronomers aren't exactly sure how galaxies form and evolve. By studying these giant time capsules, we hope to peer into our own ancient past and unravel the ultimate mysteries of how our own galaxy came to be.

NASA’s Hubble Space Telescope and its Asteroid Detection Ability Will Be Hampered by Starlink Gen2 – iTech Post
Posted: February 15, 2022 at 5:23 am
SpaceX's Starlink Gen2 satellite has recently submitted an application to the Federal Communications Commission (FCC) to deploy 30,000 Starlink Gen2 satellites.
However, NASA sent a letter to the FCC stating that it encourages the agency to do more research and careful deployment of these satellites.
NASA added that the Hubble space telescope might be affected by the deployment of the plethora of satellites since eight percent of Hubble telescope images are impacted by satellites captured during exposures.
NASA expressed that the license Starlink seeks approval for states 10,000 satellites that are positioned in or above the orbital range of Hubble.
In this case, this would double the number of Hubble's degraded images.
NASA added that it estimates that the presence of a Starlink satellite will be spotted in every single asteroid image captured by the Hubble telescope.
The agency does not take it lightly as this would mean a difficulty of detecting asteroids that might further cause harm towards the planet, the satellites, and NASA's space missions. This might also go as far as having numerous image renders that are unusable.
As reported by Ars Technica, NASA wants "additional information including spacecraft and laser specifications including deployed dimensions, communications plan, ground segment expansion, orbital spacing, and deployment schedule."
"This will inform a thorough analysis of risks and impacts to NASA's missions and enable a mitigation strategy," the report adds.

The letter that NASA sent to the FCC does not discourage the agency from rejecting the application of SpaceX Starlink Gen2. Rather, it pushes for the meticulous overseeing of the project to guarantee safe spaceflight in future missions and a long-term sustainable space environment.
It has been reported that NASA has legally expressed its concern regarding the significant increase of space satellites that might possibly cause collisions with other crewed spacecraft missions.
Space traffic might further endanger space exploration due to a possible crowded orbit.
According to Space.com, due to the five-fold increase of satellites in space, NASA expressed its concern about whether or not SpaceX's automated collision avoidance system would be capable of handling an enormous amount of traffic.
The conjunction that may possibly happen between satellites and other space crafts will likely have an effect on both crewed and uncrewed space missions since there will be more objects in close proximity.
Due to the resurfacing concern, SpaceX claims that there is zero risk in Starlink satellites colliding with other spacecraft in orbit.
As reported previously here oniTechPost, NASA told the FCC that "the assumption of zero risk from a system-level standpoint lacks statistical substantiation"
In addition, they added that with "the potential for multiple constellations with thousands and tens of thousands of spacecraft, it is not recommended to assume propulsion systems, ground detection systems, and software are 100% reliable, or that manual operations (if any) are 100% error-free."
PC Magalso reported that SpaceX's Starlink Gen2 satellites are aimed to launch as soon as next month. This leaves SpaceX hoping for the FCC to accept its proposal for deploying 30,000 satellites.

How to see the photo the Hubble Space Telescope took on your birthday – The Scotsman
Posted: February 3, 2022 at 3:37 pm
Since 1990, the Hubble Space Telescope has floated through space, taking pictures of the universe 24 hours a day, seven days a week - meaning that in its time, it has witnessed some incredible cosmic events.
Using a tool on the Nasa website, you can see what deep-space images the telescope captured on your birthday.
This is everything you need to know.
What is the Hubble Telescope?
The Hubble Space Telescope, also known as just the Hubble, is a huge telescope in space, which Nasa launched in 1990.
According to the space agency, the Hubble is as long as a large school bus and weighs as much as two adult elephants. The Hubble spends its time travelling around earth at around five miles per second, which is the equivalent of driving a car from the east coast of the US to the west coast in just 10 minutes.
The telescope faces towards space, and it takes pictures of planets, stars and galaxies. It has witnessed the birth and death of stars, black holes, galaxies that are trillions of miles away and has even seen comet pieces crash into the gases above Jupiter.
Nasa says that the Hubble has fundamentally changed our understanding of the cosmos, and its story - filled with challenges overcome by innovation, determination, and the human spirit - inspires us.
The telescope got its name from Edwin P Hubble, who was an astronomer who made important discoveries about the universe in the early 1990s.
Astronauts have visited the Hubble five times to fix it, adding new parts and cameras to the telescope. In 2020, it turned 30 years old.
How do I use the feature?
Nasa says: The Hubble explores the universe 24 hours a day, 7 days a week. That means it has observed some fascinating cosmic wonder every day of the year, including on your birthday.
To see with the Hubble saw on your birthday, you just need to head to the Nasa website.
From there, select the month and date that you were born and hit submit to see what it saw on your birthday.
Youll be shown a picture and will be given some information about what the Hubble saw. If you click on the more information option, youll be taken to a new webpage on the Hubble site which tells you all about the image.
You can easily share your image to social media, like Twitter, Facebook and Pinterest by clicking on the icons in the upper left corner. Users are encouraged to share their birthday image on social media with the hashtag #Hubble30.
The Nasa website says that for Firefox users, you might need to turn off content blocking for this site in your browser's privacy settings if youre wanting to share your Hubble birthday image on social media.
A text version of the tool is also available for screen readers.
What did the telescope see on notable dates?
These are some examples of what the Hubble Telescope saw on some notable dates throughout the years.
On 25 December 2009, the telescope saw the dwarf galaxy NGC 4215, with the image capturing intricate patterns of glowing hydrogen shaped during the star birthing process, cavities blown clear of gas by stellar winds, and bright stellar clusters.
On 1 January 2012, it saw the galaxy Leo IV, which is one of more than a dozen ultra-faint dwarf galaxies near the Milky Way.
On 31 October 2005, the Hubble saw the nebula NGC 281, with the image showing dark knots of gas and dust called Bok Globules.

Hubble telescope spots a black hole fostering baby stars in a dwarf galaxy – Space.com
Posted: January 21, 2022 at 11:23 pm
Black holes can not only rip stars apart, but they can also trigger star formation, as scientists have now seen in a nearby dwarf galaxy.
At the centers of most, if not all, large galaxies are supermassive black holes with masses that are millions to billions of times that of Earth's sun. For instance, at the heart of our Milky Way galaxy lies Sagittarius A*, which is about 4.5 million solar masses in size.
Astronomers have previously seen giant black holes shred apart stars. However, researchers have also detected supermassive black holes generating powerful outflows that can feed the dense clouds from which stars are born.
Video: Dwarf galaxys black hole triggers star formationRelated: The strangest black holes in the universe
Black hole-driven star formation was previously seen in large galaxies, but the evidence for such activity in dwarf galaxies was scarce. Dwarf galaxies are roughly analogous to what newborn galaxies may have looked like soon after the dawn of the universe, so investigating how supermassive black holes in dwarf galaxies can spark the birth of stars may in turn offer "a glimpse of how young galaxies in the early universe formed a portion of their stars," study lead author Zachary Schutte, an astrophysicist at Montana State University in Bozeman, told Space.com.
In a new study, the scientists investigated the dwarf galaxy Henize 2-10, located about 34 million light-years from Earth in the southern constellation Pyxis. Recent estimates suggest the dwarf galaxy has a mass about 10 billion times that of the sun. (In contrast, the Milky Way has a mass of about 1.5 trillion solar masses.)
A decade ago, study senior author Amy Reines at Montana State University discovered radio and X-ray emissions from Henize 2-10 that suggested the dwarf galaxy's core hosted a black hole about 3 million solar masses in size. However, other astronomers suggested this radiation may instead have come from the remnant of a star explosion known as a supernova.
In the new study, the researchers focused on a tendril of gas from the heart of Henize 2-10 about 490 light-years long, in which electrically charged ionized gas is flowing as fast as 1.1 million mph (1.8 million kph). This outflow was connected like an umbilical cord to a bright stellar nursery about 230 light-years from Henize 2-10's core.
This outflow slammed into the dense gas of the stellar nursery like a garden hose spewing onto a pile of dirt, leading water to spread outward. The researchers found newborn star clusters about 4 million years old and upwards of 100,000 times the mass of the sun dotted the path of the outflow's spread, Schutte said.
With the help of high-resolution images from the Hubble Space Telescope, the scientists detected a corkscrew-like pattern in the speed of the gas in the outflow. Their computer models suggested this was likely due to the precessing, or wobbling, of a black hole. Since a supernova remnant would not cause such a pattern, this suggests that Henize 2-10's core does indeed host a black hole.
"Before our work, supermassive black hole-enhanced star formation had only been seen in much larger galaxies," Schutte said.
In the future, the researchers would like to investigate more dwarf galaxies with similar black hole-triggered star formation. However, this is difficult for many reasons "systems like Henize 2-10 are not common; obtaining high quality observations is difficult; and so on," Schutte said. However, when the James Webb Space Telescope hopefully comes online in the near future, "we will have new tools to search for these systems," he noted.
Schutte and Reines detailed their findings in the Jan. 19 issue of the journal Nature.

What we learn of the universe leads us to God – The Catholic Register
Posted: at 11:22 pm
The universe is beautiful and weve got pictures to prove it. Come May, when the James Webb Space Telescope starts downloading deep space photos, were going to have even more pictures, and astrophysicist and cosmologist Fr. Adam Hinks just knows those pictures will be beautiful too.
Were going to get beautiful pictures from the JWST (James Webb Space Telescope) and thats super-important, Hinks told The Catholic Register. The public loves it, just because theyre beautiful pictures and they make you think about the universe. If youre a person of faith, it helps you think about God too. This is His handiwork.
This onslaught of abstract, pure beauty we see in images of galaxies, nebulas and stars is not just incidental to the science of astronomy, said the Jesuit who holds the Sutton Family Chair in Science, Christianity and Cultures at the David A. Dunlap Department of Astronomy and Astrophysics in the University of Toronto, teaches in the Christianity and Culture program at the University of St. Michaels College and in his spare time is an adjunct scholar with the Vatican Observatory.
Its not secondary. Its not irrelevant, these beautiful pictures, Hinks said. As scientists, we love them too. We certainly study them carefully. We analyze them mathematically. We try to figure out the physics. But at the same time we also love just the images. Theres further beauty when you understand the science.
For Hinks, an encounter with beauty on this scale is also an encounter with God.
When youre in a relationship with someone, when you love someone, youre interested in what that person does. This is what God has done, he said.
As a cosmologist, Hinks studies how the universe came to be what it is. Its a sort of scientific take on history, starting with the Big Bang. Hinks specialty is the very early history of the first instance of the universe, when it was fairly uniform and mostly gas.
The James Webb telescope, with its giant, golden eye that can read infrared light, is going to have the ability to peer back in time to when stars first began to form. The light that hits the James Webb will have travelled for billions of years so long that the wavelengths have stretched out and are no longer visible to ordinary telescopes on Earth, or even the Hubble Telescope that orbits high above the interference of our atmosphere.
The James Webb is about 100 times more powerful than the Hubble. The light it sees dates from about 100 million years after the Big Bang a blink of an eye in the 13.8-billion-year history of the universe. The telescope cost $9 billion (U.S.) and will take almost four months to set up and focus from NASAs Goddard space flight centre in Greenbelt, Maryland.
For now, Hinks isnt part of any of the teams of scientists who have scheduled time on the telescope to run experiments. One of his Jesuit colleagues at the Vatican Observatory is awaiting data from the JWST that will show star populations as the first galaxies formed.
Science is a team sport and even if Hinks isnt booking time on the James Webb, what the eye in the sky sees matters to the cosmologist.
I will certainly have colleagues who are involved in projects on the James Webb telescope. It will certainly impact my research, even if I dont directly work on it, he said.
Its all about filling in the blanks on the long chronicle of the universe, said Hinks.
Theres kind of some fuzzy chapters, he said. We dont have the words on the page yet.
Encountering God in cosmology is no surprise.
Its part of the Christian world view to see the universe as making sense, as something you can study, said Hinks. Christians want to know where it all came from. Those are questions that very naturally lead to scientific curiosity.
Certainly, not every scientist is Christian. But as a Christian, Hinks knows that what he learns leads him back to God.
Our faith tells us something about the origin of the universe that it comes from God, he said. What our faith doesnt tell us is, scientifically, how that works. For the science we need to go out with our telescopes and figure out the equations and all of that.
