Astronomers have used the James Webb Space Telescope to spot several of the building blocks of stars, planets, and even life in ice form swirling around two infant stars, or \"protostars.\" <\/p>\n
The complex organic molecules (COMs) spotted range from relatively simple molecules to complex compounds. Some of the familiar compounds spotted around the protostars IRAS 2A and IRAS23385 include ethanol, which we call alcohol on Earth, acetic acid found in vinegar, and formic acid, the compound that makes bee stings and ant bites painful. <\/p>\n
The discovery of the compounds around IRAS 2A is particularly interesting because these protostars, a lot like the sun, would have 4.6 billion years ago in its infancy before the formation of the planets. That means the discovery of these icy compounds may help confirm that the vital ingredients for life were delivered to Earth by comet bombardments. <\/p>\n
\"This finding contributes to one of the long-standing questions in astrochemistry,\"team leader and Leiden University researcher Will Rochasaid in a statement.\"What is the origin of COMs in space? Are they made in the gas phase or in ice? The detection of COMs in ices suggests that solid-phase chemical reactions on the surfaces of cold dust grains can build complex kinds of molecules.\" <\/p>\n

The James Webb Space Telescope (JWST) has double-checked the Hubble Space Telescope's calculations of the expanding universe, finding its older sibling telescope was spot on the money. This possibly intensifies an existing headache for cosmologists called the \"Hubble tension.\" <\/p>\n
The Hubble Tension arises from the fact that measurements of the rate of the expansion of the universe made with a cosmic fossil called the cosmic microwave background (CMB) don't tally with a measurement technique referred to as the \"cosmic distance ladder.\" One possibility for Hubble tension was that measurements made by the Hubble telescope to form the bottom rung of this ladder were inaccurate. <\/p>\n
This distance ladder is made up of \"rungs\" of different techniques to measure increasingly larger cosmic distances. The JWST discovered that the bottom rung, measurements to stars that pulse in brightness called \"Cepheid variables,\" isn't a little loose after all. Observations made with the increased resolution of the JWST revealed that a suspected error in Hubble's measurement of Cepheid variables isn't present. <\/p>\n
\"We've now spanned the whole range of what Hubble observed and we can rule out a measurement error as the cause of the Hubble tension with very high confidence,\" research leader and John Hopkins University scientist Adam Riess said in a statement. \"With measurement errors negated, what remains is the real and exciting possibility we have misunderstood the universe.\" <\/p>\n

Using the James Webb Space Telescope (JWST) researchers identified a population of supermassive black hole-powered quasars that could help explain how such objects grew to sizes equivalent to millions or billions of times that of the sun. <\/p>\n
The relatively small quasars, which were identified as tiny red dots of light, represent a transitional stage on the road to becoming truly gigantic supermassive black holes. This means that this quasar population could fill a mass gap, the existence of which has perplexed scientists. <\/p>\n
\"One issue with quasars is that some of them seem to be overly massive, too massive given the age of the universe at which the quasars are observed,\" Jorryt Matthee, lead author of the study and an assistant professor at the Institute of Science and Technology Austria, said in astatement. \"We call them the 'problematic quasars.'\" <\/p>\n

Using the James Webb Space Telescope, astronomers have observed small galaxies that existed when the universe was less than 1 billion years old, finding they were responsible for shaping the entire cosmos. <\/p>\n
The galaxies with masses less than 1 billion times that of the sun provided most of the light that transformed neutral hydrogen to ionized hydrogen during a point in the universe's evolution called the epoch of reionization. <\/p>\n
\"We're really talking about the global transformation of the entire universe,\" Hakim Atek, research lead author and an astronomer at the Institut d'Astrophysique de Paris told Space.com. \"The main surprise is that these small, faint galaxies had so much power, their cumulative radiation could transform the entire universe.\" <\/p>\n

Using the James Webb Space Telescope (JWST) astronomers have discovered an extremely red supermassive black hole that existed when the universe was under 1 billion years old. <\/p>\n
Not only is the supermassive black hole as massive as 40 million suns, it is growing by rapidly swallowing or accreting matter. Its red color comes from the shroud of gas and dust that surrounds it. <\/p>\n
\"Several other supermassive black holes in the early universe have now been found to show a similar behavior, which leads to some intriguing views of the black hole and host galaxy growth, and the interplay between them, which is not well understood,\" Princeton University researcher Jenny Greene said. <\/p>\n

Thousand-mile-per-hour winds are blowing a hail of tiny quartz crystals through the silicate-enhanced, scorching hot atmosphere of a distant gas giant planet called WASP-17b, the James Webb Space Telescope (JWST) has found. <\/p>\n
\"We knew from Hubble [Space Telescope] observations that there must be aerosols tiny particles making up clouds or haze in WASP-17bs atmosphere, but we didnt expect them to be made of quartz,\" Daniel Grant of the University of Bristol in the UK and leader of a new study on the discovery, said in astatement. <\/p>\n

Astronomers have begun measuring the most distant star ever detected, thanks to the powerful eyes of theJames Webb Space Telescope(JWST). <\/p>\n
That star, known as Earendel, wasdiscovered last yearby theHubble Space Telescope. It has taken 12.9 billion years for Earendel's light to reach Earth, meaning the star was shining less than a billion years after the Big Bang spurred our universe into existence.However, Earendel doesn't lie a mere 12.9 billion light-years away from us. <\/p>\n

The James Webb Space Telescope (JWST) has detected the most distant active supermassive black hole. <\/p>\n
The galaxy that hosts the ancientblack hole, CEERS 1019, formed fairly early in the universe's history, just 570 million years afterthe Big Bang. The active supermassive black hole at the center of CEERS 1019 is unusual not only for its age and distance but also in that it weighs in at just 9 million solar masses, meaning it's 9 million times heftier thanthe sun. <\/p>\n

New data from NASA's James Webb Space Telescope (JWST) shows that the atmosphere of a rocky exoplanet in the TRAPPIST-1 system is either non-existent or incredibly thin, making it unfavorable for hosting life as we know it. <\/p>\n
Astronomers usingJWSTwere able to calculate the amount of heat energy coming fromTRAPPIST-1 c, revealing that the dayside temperature of the rocky world is about 225 degrees Fahrenheit (107 degrees Celsius) the coolest rockyexoplanetever characterized. At this temperature, the exoplanet's atmosphere is likely extremely thin, if it exists at all, according to a statement from NASA. <\/p>\n

Shortly after the Big Bang, the universe was a dark and mysterious place.The gas between stars and galaxies was opaque, so no light could shine through. <\/p>\n
Using observations from NASA'sJames Webb Space Telescope, an international team of astronomers led by Simon Lilly of ETH Zrich in Switzerland has found how the universe changed in opacity. The team looked back in time at galaxies from the end of theEra of Reionization, a dramatic period in the universe's history in which gas was heated, cooled and then reionized (given an electrical charge once again). <\/p>\n
