A Black Hole Family Tree
Researchers may have untangled the complex origins of the two black holes involved in a recent massive collision.
Not Their First Rodeo: Gravitational Wave Detectors Spot Merging Black Holes That Have Merged Before
The gravitational wave events GW241011 and GW241110 provide strong evidence for the growth of black holes through successive mergers.
Planets Can Be Bells: The Aftermath of Major Mergers
New research suggests that giant planets likely ring like bells after they collide with other worlds.
Shortest-Period Polar Cataclysmic Variable Discovered
Gaia19bxc appears to contain a magnetic white dwarf and a metal-poor star in theory-defying close quarters — a configuration seen for the first time in a cataclysmic variable system.
A Strange Brown Dwarf Gets Stranger
A brown dwarf that made headlines for showing signs of auroral activity is back in JWST’s sights — and it’s now doubly interesting.
Investigation of the First Radio-Bright Off-Nuclear Tidal Disruption Event
The tidal disruption event AT 2024tvd happened outside the nucleus of its host galaxy, indicating the presence of a wandering or recoiling massive black hole. What can radio observations tell us about this unusual event?
Rapid Recurrent Nova May Be Challenging Perceptions
A recent study finds that a recurrent nova may be powered by a rare Be star–white dwarf binary system, broadening the scope of possible novae origins.
Researchers Spot a Rare Glowing, Growing Planet
Growing planets need to eat, and astronomers just found one snacking on gas in between the rings of a protoplanetary disk.
Supermassive Black Hole in a Super Tiny Galaxy Found with JWST
Using high-resolution JWST observations, a recent study has found a supermassive black hole at the center of an ultracompact dwarf galaxy.
