Why is the warm gas-giant exoplanet WASP-107 b so puffy? Two
independent teams of researchers have an answer. Data collected using NASA’s James Webb Space Telescope, combined with prior observations from NASA’s Hubble Space Telescope, show surprisingly little methane (CH4) in the planet’s atmosphere, indicating that the interior of WASP-107 b must be significantly hotter and the core much more massive than previously estimated. The unexpectedly high temperature is thought to be a result of tidal heating caused by the planet’s slightly non-circular orbit, and can explain how WASP-107 b can be so inflated without resorting to extreme theories of...

X-ray image of GRB221009A (Credit: NASA/Swift) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Observations by the James Webb Space Telescope are offering new clues about the nature of a massive supernova associated with GRB 221009A, the brightest gamma-ray burst astronomers have ever recorded. The
new research confirms the presence of a supernova linked to this highly energetic source of gamma rays and reveals its comparatively low production of radioactive nickel, findings that challenge our currently accepted models involving these powerful events. Astronomers hope the new findings made possible by NASA’s premier space science observatory will also help to offer unique new views into the processes that...

James Webb Space Telescope Maps Weather on Planet 280 Light Years Away, Raising Hopes for Biosignature Detection

(NASA, ESA, CSA, Ralf Crawford (STScI)) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Scientists using NASA’s James Webb Space Telescope (JWST) have successfully mapped the weather on a planet 280 light years away. Earlier
detections made by older space telescopes had hinted at the presence of an atmosphere on WASP-43b, however, the instruments aboard the JWST are the first to measure the actual weather in the planet’s atmosphere. “With Hubble, we could clearly see that there is water vapor on the dayside. Both Hubble and Spitzer suggested there might be clouds on the nightside,” explained Taylor Bell, a researcher from the Bay Area Environmental Research Institute...

Astronomy Picture of the Day - The Cigar Galaxy from Hubble and Webb

Explanation: Something strange happened to this galaxy, but what? Known
as the Cigar Galaxy and cataloged as M82, red glowing gas and dust are being cast out from the center. Although this starburst galaxy was surely stirred up by a recent pass near its neighbor, large spiral galaxy M81, this doesn't fully explain the source of the red-glowing outwardly expanding gas and dust. Evidence indicates that this material is being driven out by the combined emerging particle winds of many stars, together creating a galactic superwind. In the featured images, a Hubble Space Telescope image in visible light is shown...

The latest discoveries were made by Webb's Mid-Infrared Instrument (MIRI) instrument as part of the James Webb Observations of Young ProtoStars (JOYS+) program and revealed key chemical ingredients astronomers are looking for in the search for distant worlds that could be home to life.Given that they are young protostars, IRAS 2A and
IRAS 23385 do not appear to have planets in orbits around them yet. However, the detections of organic molecules around them are promising indicators for regions of future habitability.Along with the detection of ethanol, MIRI has also detected what astronomers believe is probably acetic acid, an ingredient commonly...

Looking deeply into space and time, two teams using NASA’s James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old. Initially
detected with NASA’s Hubble Space Telescope, this galaxy — one of the youngest and most distant ever observed — is so bright that it is challenging scientists to understand why. Now, GN-z11 is giving up some of its secrets. Vigorous Black Hole Is Most Distant Ever Found A team studying GN-z11 with Webb found the first clear evidence that the galaxy is hosting a...

"This is the first time we've been able to verify that metals heavier than iron and silver were freshly made in front of us." An
illustration of two neutron stars colliding and merging to create a kilonova blast. (Image credit: Robin Dienel/Carnegie Institution for Science) Scientists have analyzed an unusually long blast of high-energy radiation, known as a gamma-ray burst (GRB), and determined that it originated from the collision of two ultradense neutron stars. And, importantly, this result helped the team observe a flash of light emanating from the same event that confirms these mergers are the sites that create...

James Webb Space Telescope has Discovered and Enormous Remnant of the Early Universe that Astronomers say Shouldn't Exist

NASA’s James Webb Space Telescope has helped reveal an 11-billion-year-old discovery more massive than the Milky Way, which astronomers say should not exist. The
unprecedented discovery, which could upend our current understanding about the formation of galaxies, and also require scientists to rethink the mysterious nature of dark matter, involves an extremely old—and massive—galaxy that existed in the early universe which was home to an ancient population of stars. What makes the discovery unique and perplexing to astronomers is that the stars observed in this primordial galaxy should not have been able to form according to current models, because there...

Explanation: What's different about this galaxy? Very
little, which makes the Spanish Dancer galaxy, NGC 1566, one of the most typical and photogenic spirals on the sky. There is something different about this galaxy image, though, because it is a diagonal combination of two images: one by the Hubble Space Telescope on the upper left, and the other by the James Webb Space Telescope on the lower right. The Hubble image was taken in ultraviolet light and highlights the locations of bright blue stars and dark dust along the galaxy's impressive spiral arms. In contrast, the Webb image was taken...

NASA, ESA, CSA, Steve Finkelstein (UT Austin), Micaela Bagley (UT Austin), Rebecca Larson (UT Austin) Researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like surfboards and pool noodles – and are rarely round, like volleyballs or frisbees. “Roughly 50 to 80% of the galaxies we studied appear to be flattened in two dimensions,” explained lead author Viraj Pandya, a NASA Hubble Fellow at Columbia University in New York....

Explanation: Sometimes, it's the stars that are the hardest to see that are the most interesting. IC
348 is a young star cluster that illuminates surrounding filamentary dust. The stringy and winding dust appears pink in this recently released infrared image from the Webb Space Telescope. In visible light, this dust reflects mostly blue light, giving the surrounding material the familiar blue hue of a reflection nebula. Besides bright stars, several cool objects have been located in IC 348, visible because they glow brighter in infrared light. These objects are hypothesized to be low mass brown dwarfs. Evidence for this...

NASA’s Webb Finds Signs of Possible Aurorae on Isolated Brown Dwarf
|
| |
NASA ^
| JAN 09, 2024 | NASA Webb Telescope Team
Infrared emission from methane suggests atmospheric heating by auroral processes. Astronomers
using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discovery because the brown dwarf, W1935, is cold and lacks a host star; therefore, there is no obvious source for the upper atmosphere energy. The team speculates that the methane emission may be due to processes generating aurorae. These findings are being presented at the 243rd meeting of the American...
