Instrument on JWST has gone offline
The JWST is having a problem. One of its instruments, the Near Infrared Imager and Slitless Spectrograph (NIRISS), has gone offline. The NIRISS performs spectroscopy on exoplanet atmospheres, among other things......»»
Half of the mass of an early galaxy is in its central black hole
There just isn't time for something that big to grow from a supernova remnant. Enlarge / Inset shows the JWST image of the galaxy in infrared, along with the X-rays from the black hole seen by the Chandra. While the X-ray source.....»»
New Webb images show gas-rich baby galaxies setting the early universe alight
New images from the James Webb Space Telescope (JWST) have helped Australian astronomers unlock secrets of how infant galaxies started an explosion of star formation in the very early universe......»»
The JWST Has Spotted Giant Black Holes All Over the Early Universe
Giant black holes were supposed to be bit players in the early cosmic story. But James Webb Space Telescope observations are finding an unexpected abundance of the beasts......»»
Fall COVID shot uptake is an “abysmal” 7%; wastewater testing impaired
Meanwhile, a quarter of the country's wastewater testing sites are offline. Enlarge (credit: Getty | Lindsey Nicholson) More than a month since US health officials recommended updated COVID-19 vaccines for all Americans.....»»
JWST takes a detailed look at Jupiter"s moon Ganymede
Nature doesn't conform to our ideas of neatly-contained categories. Many things in nature blur the lines we try to draw around them. That's true of Jupiter's moon Ganymede, the largest moon in the solar system.....»»
New research sheds light on early galaxy formation
Researchers have developed a new computer simulation of the early universe that closely aligns with observations made by the James Webb Space Telescope (JWST)......»»
Astronomers want JWST to study the Milky Way core for hundreds of hours
To understand the universe, we need to understand the extreme processes that shape it and drive its evolution. Things like supermassive black holes (SMBHs,) supernovae, massive reservoirs of dense gas, and crowds of stars both on and off the main seq.....»»
Researchers study the analytic pricing formulas of vulnerable timer options
A timer option is a financial instrument, launched by Société Générale Corporate and Investment Banking in 2007, that allows buyers to specify the level of volatility and allows them to exercise their option at a random maturity time. In other wo.....»»
JWST looks at the debris disk around a white dwarf
Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around neutron stars. So what.....»»
The Daily Telescope: A look at a young star cluster in a nearby galaxy
In today's image, we get an infrared view of NGC 346. Enlarge / A new infrared image of NGC 346 from the Mid-Infrared Instrument on NASA’s James Webb Space Telescope. (credit: NASA, ESA, CSA, STScI, Nolan Habel (NASA-JPL)).....»»
More JWST observations are finding fewer early massive galaxies
There's a common pattern in science. We develop some new process or tool that allows us to gather all kinds of data we've never had before, the data threatens to overturn all we've assumed about some long-established theory, and then the dust settles.....»»
Loog’s clever new instrument looks like a keyboard but sounds like the real thing
The Loog Piano may be a fun, kid-size instrument, but that doesn’t mean it should look or sound like one. In 2010, Rafael Atijas set out to reimagine the kids’ guitar by making it fun, approachable, and appropriately sized for children.....»»
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.....»»
A new planet-hunting instrument has been installed on the Very Large Telescope
Exoplanet studies have come a long way in a short time. To date, 5,523 exoplanets have been confirmed in 4,117 systems, with another 9,867 candidates awaiting confirmation. With all these planets available for study, exoplanet researchers have been s.....»»
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......»»
Will Payday 3 get an offline mode?
Matchmaking issues are robbing people of their enjoyment of Payday 3. Will the ability to play offline be made an option to you in the future or not?.....»»
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.....»»
