'Marshmallow' world orbiting a cool red dwarf star
Oct 24, 2022 (SPX)
Astronomers using the WIYN 3.5-meter Telescope at Kitt Peak National Observatory in Arizona, a Program of NSF's NOIRLab, have observed an unusual Jupiter-like p...
Using Webb Telescope to study supernovae as source of heavy elements in universe
Oct 24, 2022 (SPX)
This week, Ashall began using NASA's James Webb Space Telescope to collect data on the presence of heavy elements in exploding dying stars, or supernovae. As Ja...
Webb uncovers dense cosmic knot in the early Universe
Oct 21, 2022 (ESA)
The quasar in question, SDSS J165202.64+172852.3, is an "extremely red" quasar that exists in the very early Universe, 11.5 billion years ago. Quasars are a rar...
Deep learning with light
Oct 21, 2022 (SPX)
MIT researchers have created a new method for computing directly on these devices, which drastically reduces this latency. Their technique shifts the memory-int...
Webb takes star-filled portrait of pillars of creation
Oct 20, 2022 (SPX)
Webb's new view of the Pillars of Creation, which were first made famous when imaged by NASA's Hubble Space Telescope in 1995, will help researchers revamp thei...
The most precise accounting yet of dark energy and dark matter
Oct 20, 2022 (SPX)
By putting prevailing modern cosmological theories, known as the Standard Model of Cosmology, on even firmer evidentiary and statistical footing, Pantheon+ furt...
Near-infrared light uncovers vast populations of forming stars, many still encased in dust
Oct 20, 2022 (SPX)
But this is the first time an observatory has delivered such detailed data in near-infrared light. Newly formed stars pop out in shades of pink, red, and crimso...
New tool allows scientists to peer inside neutron stars
Oct 19, 2022 (SPX)
Neutron stars are extraordinary astrophysical objects in their own right, but their extreme densities might also allow them to function as laboratories for stud...
Astronomers create new technique to assist in search for dark matter
Oct 19, 2022 (SPX)
Five times more prevalent than ordinary matter, dark matter makes up about 85% of the total mass of the universe, and about a quarter (26.8%) of the universe's ...
NASA's Swift, Fermi missions detect exceptional cosmic blast
Oct 17, 2022 (SPX)
On Sunday morning Eastern time, a wave of X-rays and gamma rays passed through the solar system, triggering detectors aboard NASA's Fermi Gamma-ray Space Telesc...
Astronomers are captivated by brightest flash ever seen
Oct 14, 2022 (AFP)
The burst of gamma-rays -- the most intense form of electromagnetic radiation -- was first detected by orbiting telescopes on October 9, and its afterglow is st...
Optical foundations illuminated by quantum light
Oct 11, 2022 (SPX)
The researchers have been able to show that quantum waves behave significantly differently from their classical counterparts and can be used to increase the pre...
Milky Way's graveyard of dead stars found
Oct 10, 2022 (SPX)
"These compact remnants of dead stars show a fundamentally different distribution and structure to the visible galaxy," said David Sweeney, a PhD student at the...
NASA's Chandra Adds X-ray Vision to Webb Images
Oct 10, 2022 (SPX)
Webb, however, will not pursue its exploration of the universe on its own. It is designed to work in concert with NASA's many other telescopes as well as facili...
NASA's Roman Mission delivers detectors to Japan's PRIME Telescope
Oct 10, 2022 (SPX)
The Roman team possesses extra detectors that will be used for other purposes. The team reserved six of the surplus detectors to serve as flight-quality backups...
Overlapping galaxies VV 191 in Webb and Hubble composite image
Oct 07, 2022 (SPX)
Webb's near-infrared data also show us the galaxy's longer, extremely dusty spiral arms in far more detail, giving them an appearance of overlapping with the ce...
Cosmic ray protons reveal new spectral structures at high energies
Oct 06, 2022 (SPX)
But recent observations made using magnetic spectrometers for low energy levels and calorimeters for high energy levels has hinted at a deviation from this powe...
Spin flips show how galaxies grow from the cosmic web
Oct 06, 2022 (SPX)
The new study finds that galaxies with bigger bulges tend to spin perpendicular to the filaments in which they are embedded, while galaxies with smaller bulges ...
Astronomers find a cataclysmic pair of stars with the shortest orbit yet
Oct 06, 2022 (SPX)
Astronomers at MIT and elsewhere have now discovered a stellar binary, or pair of stars, with an extremely short orbit, appearing to circle each other every 51 ...
NASA, SpaceX study boosting Hubble to extend its lifespan
Sep 29, 2022 (AFP)
The renowned observatory has been operating since 1990 about 335 miles (540 kilometers) above Earth, in an orbit that slowly decays over time. Hubble has no on-...
