Red dwarf stars are cosmic killers that eat their own planets

Astronomers have discovered the first evidence that tiny red dwarf stars can devour their own planets.

NASA’s Roman Mission Preps to Unveil New Populations of Faraway Worlds
NASA’s Roman Mission Preps to Unveil New Populations of Faraway Worlds

NASA’s Nancy Grace Roman Space Telescope is poised to make a major leap in the hunt for worlds outside our solar system, known as exoplanets. Scientists expect the mission to reveal around 100,000 worlds — a staggering leap compared to the nearly 6,300 found so far thanks to NASA missions working in tandem with other […]

Scientists just found a supercharged supernova — powered up by a magnetic star corpse

NASA’s Fermi Gamma-ray spacecraft has observed a super-bright, supercharged supernova explosion powered up by the creation of a highly magnetic dead star, or magnetar.

NASA’s Fermi Glimpses Power Source of Supercharged Supernovae
NASA’s Fermi Glimpses Power Source of Supercharged Supernovae

An international team studying data from NASA’s Fermi Gamma-ray Space Telescope concludes the mission detected a rare, unusually luminous supernova. The researchers say it likely received its power-up from a supermagnetized neutron star born in the stellar collapse that triggered the explosion.

Hubble Survey Sets Up Roman’s Future Look Near Milky Way’s Center
Hubble Survey Sets Up Roman’s Future Look Near Milky Way’s Center

The Milky Way’s galactic bulge, the bulbous region that surrounds the galactic center, contains a dense collection of stars, planets, and other free-floating objects. This region has been studied for decades with numerous ground-based and space-based telescopes, including NASA’s Hubble and James Webb space telescopes. Soon, NASA’s Nancy Grace Roman Space Telescope will be the […]

NASA’s Roman Poised to Transform Hunt for Elusive Neutron Stars
NASA’s Roman Poised to Transform Hunt for Elusive Neutron Stars

Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way galaxy. However, most of them are effectively invisible. A new study published in Astronomy and Astrophysics suggests NASA’s upcoming Nancy Grace Roman Space Telescope could spot them anyway. Using detailed simulations of […]

Scientists have found a hidden galaxy inside the Milky Way, and they’re calling it Loki

A new study suggests the Milky Way consumed an ancient dwarf galaxy billions of years ago, and its stellar remains may still be embedded within ours.

Why do some stars become ‘supernova impostors’? Astronomers still don’t quite know

Astronomers call this “eruptive mass loss,” and it’s a stellar drama we’re still trying to fully grasp.

Starbirth shuts down 40,000 light-years from the Milky Way’s core — and astronomers don’t know why

Astronomers have found the boundary of star formation in the Milky Way’s spiral disk — and it’s not as far out from the center of our galaxy as you might imagine.

Scientists learn how much baby stars in Orion weigh — by watching their dance moves

By peering deep inside Orion’s star-forming gas clouds, radio astronomers have been able to directly measure the masses of young binary stars, confirming that our theoretical models are on the right lines.
