Cosmic chocolate pralines: General neutron star structure revealed
Nov 16, 2022 (SPX)
The greatest challenge is to simulate the extreme conditions inside neutron stars, as they can hardly be recreated on Earth in the laboratory. There are therefo...
Astronomers capitalize on early access to James Webb Space Telescope data
Nov 15, 2022 (SPX)
In a paper published in The Astrophysical Journal Letters, the researchers describe their examination of the nearby galaxy NGC 7469 with the JWST's ultrasensiti...
Gold-rich stars came from ancient galaxies
Nov 15, 2022 (SPX)
Stars are thermonuclear chemical factories that produced most of the elements incorporated into planets. Most elements heavier than iron, including precious met...
Searching for traces of dark matter with neutron spin clocks
Nov 14, 2022 (SPX)
Recently, following a precision experiment developed at the Albert Einstein Center for Fundamental Physics (AEC) at the University of Bern, an international res...
2400 new eyes on the sky to see cosmic rainbows
Nov 14, 2022 (SPX)
In addition to cameras, astronomers also use instruments known as spectrographs to study celestial object. A spectrograph breaks the light from an object into i...
Black holes don't always power gamma-ray bursts, new research shows
Nov 11, 2022 (SPX)
A sub-type of GRB known as a short-duration GRB starts life when two neutron stars collide. These ultra-dense stars have the mass of our Sun compressed down to ...
Red-supergiant supernova images reveal secrets of an earlier Universe
Nov 10, 2022 (SPX)
The paper is published in Nature, the world's leading peer-reviewed, multidisciplinary science journal. "This is the first detailed look at a supernova at a muc...
How MIRI became Webb's coolest instrument
Nov 09, 2022 (ESA)
At mid-infrared wavelengths, the Universe is a very different place from the one we are used to seeing with our eyes. Stretching from 3 to 30 micrometres, mid-i...
Magnetized dead star likely has solid surface
Nov 07, 2022 (SPX)
The team looked at IXPE's observation of magnetar 4U 0142+61, located in the Cassiopeia constellation, about 13,000 light years away from Earth. This was the fi...
IceCube neutrinos provide new view of active galaxy
Nov 04, 2022 (SPX)
The scientists have found that NGC 1068, also known as Messier 77, in the constellation of Cetus, is a high-energy neutrino emitter. They have observed the part...
Planets can be anti-aging formula for stars
Nov 03, 2022 (SPX)
While the anti-aging property of "hot Jupiters" (that is, gas giant exoplanets that orbit a star at Mercury's distance or closer) has been seen before, this res...
ALMA observatory in Chile targeted by cyberattack
Nov 02, 2022 (AFP)
ALMA, the world's most powerful telescope for observing molecular gas and dust, studies the building blocks of stars, planetary systems, galaxies and life itsel...
Overcoming the optical resolution limit
Nov 02, 2022 (SPX)
Imaging below the resolution limit is often achieved with systems that use probe labeling, such as fluorescence microscopy, which requires preparation of the sa...
Webb reveals dust, structure in Pillars of Creation
Oct 28, 2022 (SPX)
This is not an ethereal landscape of time-forgotten tombs. Nor are these soot-tinged fingers reaching out. These pillars, flush with gas and dust, enshroud star...
Webb offers never-before-seen details of early universe
Oct 27, 2022 (SPX)
Today, we sit down with three astronomers working on Webb to talk about their latest findings. The team members are Dan Coe of AURA/STScI for the European Space...
VLA finds cosmic rays driving galaxy's winds
Oct 27, 2022 (SPX)
Such winds are responsible for slowing the rate of star formation as galaxies evolve over time. However, shock waves from supernova explosions and energetic, bl...
Observation puzzles researchers
Oct 27, 2022 (SPX)
Instead, the observations are consistent with the predictions of an alternative theory of gravity. However, this is controversial among experts. The results hav...
Rare earth element synthesis confirmed in neutron star mergers
Oct 27, 2022 (SPX)
A research group led by Nanae Domoto, a graduate student at the Graduate School of Science at Tohoku University and a research fellow at the Japan Society for t...
New laser could reshape the application of integrated photonics
Oct 25, 2022 (SPX)
The project, described in Nature Communications, was co-led by John Bowers, distinguished professor at University of California/Santa Barbara, and Kerry Vahala,...
'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...
