Study reveals new source of the heavy elements
Columbus OH (SPX) May 12, 2025 Magnetar flares, colossal cosmic explosions, may be directly responsible for the creation and distribution of heavy elements across the universe, suggests a new study. 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 fresh look at old archival data, researchers now estimate that up to 10% of these heavy elements in the Milky Way are derived from the ejections of highly magnetized neutron star ... read more |

New evidence suggesting magnetar origin of GRBsBeijing, China (SPX) Apr 16, 2025 How gamma-ray bursts (GRBs), the most powerful and spectacular explosions known in the universe since the Big Bang, fuel their high-energy radiations? What kind of physical reactions can trigger and ... more 
Half of the universe's hydrogen gas, long unaccounted for, has been foundBerkeley CA (SPX) Apr 16, 2025 Astronomers tallying up all the normal matter - stars, galaxies and gas - in the universe today have come up embarrassingly short of the total matter produced in the Big Bang 13.6 billion years ago. ... more 
Do "completely dark" dark matter halos exist?San Diego CA (SPX) Apr 14, 2025 Every galaxy is thought to form at the center of a dark matter halo - a region of gravitationally bound matter that extends far beyond the visible boundaries of a galaxy. Stars are formed when gravi ... more

Sound waves reveal secrets of stellar evolution and galactic history
Sydney, Australia (SPX) Apr 03, 2025 A team led by UNSW Sydney has harnessed the sound frequencies emitted by stars to trace their life cycles and uncover the past and future of our galaxy. The research, focusing on 27 stars in the M67 cluster located 2700 light years from Earth, offers new insight into how stars like our Sun evolve. 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 gaseous cloud around four billion years ago. Des ... read more
