Are gamma-ray bursts powered by a star’s collapsing magnetic fields? When a massive star in a distant galaxy collapses, forming a black hole, two giant jets of light-emitting plasma shoot from its core. These extremely […]
Free-floating stars in the Milky Way’s bulge The path of a light beam is bent by the presence of mass, as explained by General Relativity. A massive body can therefore act like a lens—a so […]
Team discovers quasar tsunamis capable of preventing stars from forming Using the unique capabilities of NASA’s Hubble Space Telescope, a team of astronomers led by Virginia Tech’s Nahum Arav has discovered the most energetic outflows […]
NASA selects proposals to study volatile stars, galaxies, cosmic collisions NASA has selected proposals for four missions that would study cosmic explosions and the debris they leave behind, as well as monitor how nearby stellar […]
A new theory of magnetar formation Magnetars are neutron stars endowed with the strongest magnetic fields observed in the universe, but their origin remains controversial. In a study published in Science Advances, a team of scientists […]
Astronomers identify nearly 3,000 candidate stars of a nearby star-forming galaxy Using the United Kingdom Infrared Telescope (UKIRT) and NASA’s Spitzer Space Telescope, astronomers have conducted photometric observations of a nearby star-forming galaxy known as […]
