Tidal disruption events occur when a star passes a little too close to a supermassive black hole, getting torn apart in the process. Does this happen more frequently in an unusual type of galaxy?
Where should we hunt for potentially habitable planets? A recent study has generated a catalog of the habitable zones around nearby stars.
What generated the radiation that reionized our universe? The recent discovery of multiple distant galaxies offers evidence for how this process occurred.
What if Type Ia supernovae aren’t as consistent as we thought? A recent study investigates the dependence of these “standard candles” on the metallicity of their environment.
A pair of red-giant twins may be a key to weighing stars using starquakes in their interiors.
A recent study shows that WD 1145+017, a white dwarf surrounded by disintegrating planetary bodies, has evolved dramatically since its discovery last year.
Big news: LIGO has detected its first gravitational-wave signal! What does this mean for black-hole astrophysics?
If LIGO finds gravitational waves, could JWST be used in the future to follow up on detections of some compact-object mergers?
Images of two powerful solar prominence eruptions have helped astronomers model how these eruptions travel away from the Sun.
Is the planet Kepler-454b rocky, like a large Earth? Or gaseous, like a small Neptune? A recent study finds out.
The Large Area Telescope on board the Fermi Gamma-ray Space Telescope has received an upgrade that increased its sensitivity by a whopping 40% — and nobody had to travel to space to make it happen.
