Astronomers report most distant known galaxies, detected and confirmed by JWST
Dec 12, 2022 (SPX)
Initial observations from JWST yielded several candidate galaxies at extreme distances, as had earlier observations with the Hubble Space Telescope. Now, four o...
NASA's retired SOFIA aircraft finds new home at Arizona Museum
Dec 09, 2022 (SPX)
"The SOFIA mission has a powerful potential to inspire, from its discoveries about the unknown in our universe, to the engineering achievements that broke new g...
Hubble detects ghostly glow surrounding our Solar System
Dec 09, 2022 (SPX)
To find out, astronomers decided to sort through 200,000 images from NASA's Hubble Space Telescope and made tens of thousands of measurements on these images to...
Unusual gamma-ray burst reveals previously undetected hybrid neutron-star merger event
Dec 08, 2022 (SPX)
"Astronomers have long believed that gamma-ray bursts fell into two categories: long-duration bursts from imploding stars and short-duration bursts from merging...
Gamma-ray burst is 'Rosetta Stone' for finding neutron star collisions
Dec 08, 2022 (SPX)
The event, detected in December 2021 by NASA's Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope, was a gamma-ray burst - an immensely ener...
Kilonova discovery challenges our understanding of gamma-ray bursts
Dec 08, 2022 (SPX)
Gamma-ray bursts (GRBs) - the most energetic explosions in the Universe - come in two varieties, long and short. Long GRBs, which last a couple of seconds to on...
Researchers say space atomic clocks could help uncover the nature of dark matter
Dec 06, 2022 (SPX)
Dark matter makes up more than 80 per cent of mass in the universe, but it has so far evaded detection on Earth, despite decades of experimental efforts. A key ...
NASA's Roman Mission completes key optical components
Dec 06, 2022 (SPX)
After light is reflected and focused by Roman's primary and secondary mirrors, it will pass through the element wheel. The focused and filtered light will then ...
Australia starts building 'momentous' radio telescope
Dec 05, 2022 (AFP)
When complete, the antennas in Australia and a network of dishes in South Africa will form the Square Kilometre Array (SKA), a massive instrument that will aim ...
Flying an interstellar telescope
Dec 01, 2022 (SPX)
"It's a little bit of wonder, a little bit of amazement and in some ways, a deep sense of humility having a small role in it," said Peralta, a Raytheon Intellig...
Non-detection of key signal helps determine what first galaxies were and were not like
Nov 29, 2022 (SPX)
Using data from India's SARAS3 radio telescope, researchers led by the University of Cambridge were able to look at the very early Universe - just 200 million y...
New device can control light at unprecedented speeds
Nov 29, 2022 (SPX)
Generating a freestanding 3D hologram would require extremely precise and fast control of light beyond the capabilities of existing technologies, which are base...
Astronomers observe intra-group light - the elusive glow between distant galaxies
Nov 24, 2022 (SPX)
Lead author of the study published in MNRAS, Dr Cristina Martinez-Lombilla from the School of Physics at UNSW Science, said "We know almost nothing about intra-...
Short gamma-ray bursts traced farther into distant universe
Nov 23, 2022 (SPX)
The astronomers also found that more SGRBs occurred at earlier times, when the universe was much younger - and with greater distances from their host galaxies' ...
How Webb's NIRSpec instrument opened up 200 windows to our origins
Nov 21, 2022 (ESA)
The answers lie buried in the far distant Universe, so distant that the light traveled billions of years to reach us, carrying the images of the first galaxies ...
The tilt in our stars: the shape of the Milky Way's halo of stars is realized
Nov 21, 2022 (SPX)
The findings - published this month The Astronomical Journal - offer insights into a host of astrophysical subject areas. The results, for example, shed light o...
Webb draws back curtain on universe's early galaxies
Nov 18, 2022 (SPX)
"Everything we see is new. Webb is showing us that there's a very rich universe beyond what we imagined," said Tommaso Treu of the University of California at L...
WALLABY builds an intergalactic map in the outback
Nov 17, 2022 (SPX)
Hundreds of galaxies have been surveyed in Phase 1 of WALLABY, covering 180 square degrees of the observable sky-the equivalent area of over 700 full moons. Ove...
Webb catches fiery Hourglass as new star forms
Nov 17, 2022 (SPX)
The protostar itself is hidden from view within the "neck" of this hourglass shape. An edge-on protoplanetary disk is seen as a dark line across the middle of t...
Advanced light source upgrade approved to start construction
Nov 16, 2022 (SPX)
"The ALS upgrade is an amazing engineering undertaking that is going to give us an even more powerful scientific tool," said Berkeley Lab Director Michael Withe...
