Hubble telescope celebrates 25 years of mind-blowing imagery

Posted: at 7:51 am

NASA celebrates 25 years of discovery and beautiful imagery with the Hubble Space Telescope this month.

Although Hubble was launched from Space Shuttle Discovery in 1990 the telescope did not produce any images until 1995, because the large mirrors were put on incorrectly. A series of space-walks were conducted by astronauts to fix the mirrors and get Hubble back in business.

Since 1995, when the first image from Hubble was transmitted to Earth, the telescope has inspired generations of space enthusiasts with the stellar images of supernovas, nebulae, galaxies and planets.

Hubble has made more than 1 million observations since its mission began. The school-bus sized telescope can see more than 13.4 billion light years from Earth, making it one of the most productive scientific instruments in history.

Hubbles images have inspired symphony orchestra compositions, spotted galaxies thatshouldnt exist and made some of the greatest discoveries in astronomy.

NASA released a special collection of images from Hubbles portfolio and will host events around the world leading up to the anniversary on April 24, and many allow online participation. See a full list of events here.

At Kennedy Space Center Visitors Complex, there will be three days of commemorative events from April 24-26 including a projection mapping show with 200 Hubble images, photo gallery of large-scale images, hands-on activity stations, the Hubble 3D IMAX movie and presentations from NASA scientists, astronomers, astrophysicists and astronauts. These activities are included in admission to the complex, but guests can opt to pay more for a special event on April 24 from 4-11 p.m., the Hubble After Hours Adventure for $85.

That price includes two-day admission to the complex, opportunity to see the launch of the SpaceX Falcon 9 rocket slated for April 24, a stargazing event, laser astronomy tour of the night sky, a Q&A session with NASA astronaut and astro-geophysicist Dr. Sam Durrance, buffet dinner, snack and commemorative T-shirt and glow stick. Details on KSC's events can be found here.

Take a look at the Hubble Telescope 25th anniversary gallery above and prepare to be amazed.

NASA celebrates Hubble Space Telescopes 25th anniversary

Posted: April 7, 2015 at 9:48 am

The National Aeronautics & Space Administration (NASA) is preparing a documentary to celebrate the 25th anniversary of the Hubble Space Telescope, which helped astronomers discover a lot of previously-unknown things about the universe.

The Hubble Telescope was named after Astronomer Edwin Hubble, who used the biggest telescope at the Mt. Wilson Observatory in California in 1920s. To pay tribute to the late astronomer, NASA named the Hubble telescope after him and launched it on April 24, 1990.

David Gaynes, the director of the Hubble documentary, said the telescopes wide popularity among the general public in addition to science community was a testament to its success.

Speaking on the topic, Gaynes added, The achievement of Hubble is even greater than the sum of all the science and wonder the mission has generated so great its hard to articulate the feeling, though so many of us recognize it and attempt to describe it.

The telescope, which was the most powerful space telescope of its time, was launched into the space using shuttle Discovery from Kennedy Space Station. It was deployed at an altitude of 345 miles in Earths orbit.

Equipped a primary 2.4-meter mirror, the 13.3-meter-long Hubble Space telescope generates nearly ten terabyte of data per annum.

Launch Pad Lecture: Celebrating Hubble's 25th Anniversary

Posted: at 10:51 pm

Courtesy photo - NASA The Hubble cameras revisited the Pillars of Creation, originally pictured in 1995. The result was clearer sharper images. Stars are forming inside the towering structures of cold gas and dust. The pillars are located some 6,500 light-years away, in the Eagle Nebula, toward the constellation of Serpens.

New Mexico Museuam of Space History Education Director Dave Dooling will discuss the accomplishments that resulted from the launch of the Hubble Space Telescope.

Dooling is familiar Hubble since its inception. He worked as science reporter for Huntsville Times in Alabama and for Perkin-Elmer who built the telescope. He wrote documentation for maintenance and refurbishment of the telescope in space.

Although planning for Hubble started in the early 70s, it wasn't launched until 1990. Since then, the Hubble has sent back more than 45 terabytes of information. For those unfamiliar with a terabyte, one terabyte equals 1,023 gigabytes.

The Hubble space telescope was launched into low Earth orbit on April 24, 1990. It remains operational. With a mirror measuring nearly 8 feet, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared spectra.

The telescope was named after astronomer Edward Hubble. He proposed the expanding universe theory state. Hubble's findings fundamentally changed the scientific view of the universe.

The Hubble telescope has led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.

Dooling said he would be hard pressed to pick out what was the most important discovery made. He explained if he were to try and pick out the top 10 at a conference, there would be an outcry as scientists came up with 10 others of equal import.

Dooling said that one of the most stunning occurred when astronomers pointed Hubble at an empty area of sky near Ursa Major, just above the Big Dipper, and discovered hundreds of distant here-to-fore galaxies. "They did this in December of 1995 for a 10-day period," he said. "They stacked the images, taking 342 images with 43 hours of exposure time. Over 900 scientific papers have cited this single discovery."

The portion of sky scrutinized was small yet it not only proved the enormity of the universe but just how crowded a place it was.

NASA confirms Hubble telescope successor is on-time, on-budget for 2018

Posted: at 10:50 pm

NASA officials have told Congress that the Hubble Space Telescopes successor, the James Webb Space Telescope, is currently on-time and budget after early delays and cost overruns threatened to doom the project. The JWST offers a number of improvements and enhancements over the Hubble, though NASA has said publicly that it prefers to think of the next-generation telescope as a successor rather than a replacement.

The JWSTs primary mirror is far larger than Hubbles, at over 21 feet in diameter, compared with about 8 feet for Hubble. The new telescopes collecting area is more than 7x larger, and it uses a new type of mirror thats never been deployed at this scale in a space-based telescope. Each pane of beryllium (there are 18 in total) can be adjusted independently of the others. Hubble, in contrast, deployed a conventionally ground mirror.

Despite the vast difference in size, Webbs mirror actually weighs a fraction of what Hubbles does. The conventional mirror aboard the Hubble clocks in at 2,200 lbs, compared to just 1,375 lbs for the JWST.

Webbs mirror design and larger gathering area will allow it to peer farther back in time all the way back to 100 million to 250 million years after the Big Bang, compared with 800 million to 1 billion years for Hubble. The Webb isnt optimized for optical wavelengths its specialization is the infrared spectrum but itll be capable of imaging in spectrums friendly to the human eye, and with far greater resolution than what Hubble can achieve. The image below is a simulation of how the Webb is expected to perform compared with Hubble.

The James Webbs detectable spectrum is also much larger than its predecessors. While still tiny next the largest Earth-based telescopes, the deep infrared capabilities of the Webb telescope and its location should allow it to assist in the ongoing search for habitable planets and even alien life.

The James Webb telescope is years behind schedule, and substantially over its originally proposed budget, which raises the question of whether the telescope can overcome these initial obstacles and achieve successful results. Many of these issues originally plagued the Hubble telescope. Originally, the HST was meant to launch in 1983, but a similar morass of technical issues and the unexpected loss of the Challenger delayed deployment until 1990. After launch, NASA discovered that the HSTs main mirror had been incorrectly ground. For three years, Hubbles mission was severely curtailed, as NASA built a corrective lens to be installed over the improperly ground mirror.

With the James Webb, there will be no such margin for error. Unlike Hubble, which was placed in Earth orbit and designed to be serviced by the shuttle, the Webb will be placed in Sun-Earth L2 LaGrange points. LaGrange Points are positions in space where the gravitational pull of large masses equal the centripetal force required for a small object (in this case, a telescope) to move with them. An object in Earths L2 point remains in approximately the same position relative to our planet and the Sun, and can maintain its location with minimal use of fuel.

More than 20 years after deployment, the Hubble Space Telescope has become one of the most enduring missions NASA has ever launched. For many people, the images Hubble beams back of our universe are the public face of NASA, and thats a mission every bit as critical as scientific research. The James Webb telescope will inherit that mantle when it launches in 2018 heres hoping for a smooth debut and a long, storied career.
