How Often Do Black Holes Get Kicked Out of Star Clusters?
Gravitational-wave “kicks” might eject black holes from star clusters, preventing them from forming even more massive black holes.
A Young Star’s Disk Dilemma
Astronomers think CI Tauri hosts a massive planet, but observations of its disk don’t give any sign of one. What’s really going on around this star?
What’s Lurking in the Ticks from Cosmic Clocks?
How can ticking stellar clocks be used to search for ripples in the fabric of spacetime, and how close are we to detecting these waves?
Extragalactic UFOs: Ultrafast Outflows from Black Holes
Still not aliens, sorry! These otherworldly outflows are powerful enough to unbind galactic gas and accelerate particles to relativistic speeds.
Radio Eyes on Titan’s Molecules
What can observations of three nearly identical molecules tell us about how they formed?
Making Heavy Metals with High-Energy Collisions
What do gold and europium have in common? They both form when compact objects like neutron stars and black holes collide.
Mapping Planet-Forming Disks with ALMA
A new special issue takes a deep dive into the chemistry of protoplanetary disks around five young, nearby stars.
Sizing the Sun from a Solar Eclipse
A team of amateur astronomers from around the world have measured the diameter of the Sun during a total solar eclipse, a measurement that hasn’t been updated in nearly a century.
The Case for an Active Volcano on Venus
Using data from Venus’s superheated surface and super-thick atmosphere, researchers find that a volcano in Venus’s Imdr Regio might be active today.
