Study reveals new source of the heavy elements
May 12, 2025 (SPX)
For decades, astronomers only had theories about where some of the heaviest elements in nature, like gold, uranium and platinum, come from. But by taking a fres...
The Squid Galaxy's neutrino game just leveled up
May 12, 2025 (SPX)
The "eyes" are a collection of detectors buried in a cubic kilometer of ice called the IceCube Neutrino Observatory. Theoretical physicists from UCLA, the Unive...
NASA's NICER Maps Debris From Recurring Cosmic Crashes
May 07, 2025 (SPX)
Scientists have only recently encountered this class of X-ray flares, called QPEs, or quasi-periodic eruptions. A system astronomers have nicknamed Ansky is the...
Magnetar flares emerge as possible source of early cosmic gold
May 02, 2025 (SPX)
"It's a pretty fundamental question in terms of the origin of complex matter in the universe," said Anirudh Patel, a doctoral student at Columbia University in ...
A Cosmic Explosion Forged Heavy Elements Like Gold and Platinum
May 01, 2025 (SPX)
The lightest elements, hydrogen and helium, were formed mainly in the Big Bang that gave birth to the Universe. Somewhat heavier elements, such as oxygen and ir...
New Horizons creates first Lyman alpha map of the galactic sky
Apr 30, 2025 (SPX)
"Understanding the Lyman-alpha background helps shed light on nearby galactic structures and processes," said SwRI's Dr. Randy Gladstone, the study's lead inves...
Nearby molecular hydrogen cloud discovered using far ultraviolet light
Apr 30, 2025 (SPX)
Eos is among the largest single sky structures discovered and is believed to be a potential cradle for future star formation. The cloud's presence had gone unno...
Shockwave mapping reveals hidden plasma structures near Earth
Apr 23, 2025 (SPX)
Pulsars, the spinning remnants of dead stars, emit pulses of radio waves that can twinkle or "scintillate" as they pass through uneven interstellar plasma. Dr. ...
Cosmic radio tuning may reveal dark matter within 15 years
Apr 22, 2025 (SPX)
Dark matter, which remains invisible to direct observation, is believed to account for up to 85 percent of the Universe's mass. Axions, if they exist, would be ...
The most ancient Milky Way-like galaxy yet observed
Apr 22, 2025 (SPX)
Astrophysicists have long believed that large spiral galaxies such as the Milky Way require several billion years to evolve. Early galaxies, by contrast, were a...
New evidence suggesting magnetar origin of GRBs
Apr 16, 2025 (SPX)
Possible Mechanisms Different models have been proposed to fathom this mystery. Blackholes, with their horrible, disruptive pulls on subjects within their gravi...
Half of the universe's hydrogen gas, long unaccounted for, has been found
Apr 16, 2025 (SPX)
New measurements, however, seem to have found this missing matter in the form of very diffuse and invisible ionized hydrogen gas, which forms a halo around gala...
Research reveals gravitational forces may be dismantling Milky Way's small neighbor
Apr 14, 2025 (SPX)
Researchers Satoya Nakano and Kengo Tachihara tracked the movement of around 7,000 massive stars within the SMC. These stars, each more than eight times the mas...
Research reveals tidal forces disrupting nearby dwarf galaxy
Apr 14, 2025 (SPX)
"When we first got this result, we suspected that there might be an error in our method of analysis," said Tachihara. "However, upon closer examination, the res...
Do completely dark dark matter halos exist?
Apr 14, 2025 (SPX)
Now Ethan Nadler, a computational astrophysicist at UC San Diego, has calculated the mass below which halos fail to form stars. This work was done using analyti...
Galaxies stopped growing sooner than cosmic models predict
Apr 03, 2025 (SPX)
Galaxies in the early cosmos typically drew in gas from intergalactic space, fueling star formation and building up mass in a self-sustaining cycle. Yet this gr...
Webb telescope captures images, insight from one of Milky Way's most extreme environments
Apr 03, 2025 (SPX)
In a new study, a team of scientists used observations from NASA's James Webb Space Telescope to study Sagittarius C in unprecedented detail. The research was l...
Sound waves reveal secrets of stellar evolution and galactic history
Apr 03, 2025 (SPX)
Dr Claudia Reyes, the study's lead author and a PhD graduate from UNSW's School of Physics, analyzed the M67 cluster-a stellar family formed from the same gaseo...
Star-mapping space telescope Gaia sent into 'retirement orbit'
Mar 27, 2025 (AFP)
Since launching in 2013, the telescope has been charting the positions, motion and properties of nearly two billion stars to create a vast map of the Milky Way,...
Space telescope Gaia sent into 'retirement' but legacy endures
Mar 27, 2025 (AFP)
Since launching in 2013, the telescope has been charting the positions, motion and properties of nearly two billion stars to create an unparalleled map of our h...
