The first JWST spectrum of the GRB 221009A afterglow
Gamma-ray bursts are the most energetic and luminous events known to occur in the Universe. Short-lived flashes of gamma rays that typically last from a a tenth of a second to less than an hour, gamma-ray bursts may for a brief period of time outshin.....»»
Isotope database will help Mexican communities better understand hydrology processes
With a population of 127 million and a land mass about a fifth the size of the United States, Mexico has a large spectrum of climates and landscapes, ranging from mountains to coastal regions and from deserts to glaciers. Because of these variations,.....»»
New observations of flares from distant star could help in search for habitable planets
Astrophysicists have used the James Webb Space Telescope (JWST) to take a close look at a volatile star......»»
Can JWST tell the difference between an exoEarth and an exoVenus?
As of October 2023, astronomers have discovered 5,506 exoplanets orbiting other stars. That number is growing daily, and astronomers are hoping, among other things, to find Earth-like worlds. But will we know one when we see it? How might we be able.....»»
Bursts of star formation explain mysterious brightness at cosmic dawn
When scientists viewed the James Webb Space Telescope's (JWST) first images of the universe's earliest galaxies, they were shocked. The young galaxies appeared too bright, too massive and too mature to have formed so soon after the Big Bang. It would.....»»
Scientists use Webb, SOFIA telescopes to observe metallic asteroid
Southwest Research Institute scientists are using telescopes to observe the asteroid Psyche in the infrared, providing context for NASA's upcoming Psyche mission. Dr. Stephanie Jarmak is using the James Webb Space Telescope (JWST) to look for water s.....»»
What"s the link between gamma ray bursts and supernovae? It might be binary stars
Gamma-ray bursts (GRBs) are some of the most violent events in the universe. Some have a power output equivalent to all of the other stars in the observable universe, at least in the spectrum of gamma rays. But we know very little about them. A new p.....»»
The delicate balance of setting central bank interest rates
As the Bank of Canada prepared to announce its decision on interest rates in early September, Tiff Macklem, the bank's governor, received imploring letters from premiers spanning both the country and the political spectrum......»»
Researchers fabricate chip-based optical resonators with record low UV losses
Researchers have created chip-based photonic resonators that operate in the ultraviolet (UV) and visible regions of the spectrum and exhibit a record low UV light loss. The new resonators lay the groundwork for increasing the size, complexity and fid.....»»
The interaction between AGN and starburst activity as viewed with JWST
With excellent sensitivity and spatial and spectral resolutions, the James Webb Space Telescope (JWST) presents an unprecedented opportunity to promote our understanding of the evolutionary processes of galaxies......»»
JWST discovers massive and compact quiescent galaxy
Astronomers have reported the discovery of a new galaxy using the James Webb Space Telescope (JWST) as part of the JWST COSMOS-Web survey. The newfound object, designated JWST-ER1 is a massive and compact quiescent galaxy. The findings were detailed.....»»
Machine learning algorithms can find anomalous needles in cosmic haystacks
The face of astronomy is changing. Though narrow-field point-and-shoot astronomy still matters (JWST anyone?), large wide-field surveys promise to be the powerhouses of discovery in the coming decades, especially with the advent of machine learning......»»

New Type I supernova discovered with JWST
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed the galaxy cluster PLCK G165.7+67.0. The observational campaign resulted in the detection of a new Type I supernova. The finding is reported in a paper pub.....»»
Possible hints of life found on distant planet. How excited should we be?
Data from the James Webb Space Telescope (JWST) has shown that an exoplanet around a star in the constellation Leo has some of the chemical markers that, on Earth, are associated with living organisms. But these are vague indications. So how likely i.....»»
How can we bring down the costs of large space telescopes?
We're all basking in the success of the James Webb Space Telescope. It's fulfilling its promise as our most powerful telescope, making all kinds of discoveries that we've been anticipating and hoping for. But the JWST's story is one of broken budgets.....»»
Autopsy of a star reveals what was eviscerated by a monster black hole
From the interior of a star to the accretion disk of a black hole. Enlarge / Ions of nitrogen and carbon show up in the spectrum of X-rays from a black hole's accretion disk. (credit: NASA/Chandra) Even huge stars are no.....»»
Planning is underway for NASA"s next big flagship space telescope
NASA's James Webb Space Telescope (JWST) has only been operational for just over a year, but this isn't stopping the world's biggest space agency from discussing the next big space telescope that could serve as JWST's successor sometime in the future.....»»
JWST accidentally discovers 21 brown dwarfs
