Bright Galaxies Blowing Bubbles

Astrobites reports on an investigation of ultraviolet-bright galaxies during the epoch of reionization.

NASA’s Double Asteroid Redirection Test (DART) spacecraft will slam into an asteroid today. Back home on Earth, researchers carried out an impact experiment of their own.

Artist's impression of a binary system containing a massive main-sequence star and a black hole

Black holes, neutron stars, and white dwarfs sometimes announce their presence when they accrete matter from a stellar companion, but many more may be hiding quietly in binary systems across the Milky Way.

Simulating a Plateauing Supernova

Can models explain why supernova SN 2021yja took a detour as it dimmed, staying the same brightness for weeks before fading again?

Testing a New Way to Make Mars’s Moons

Did Mars’s two small moons form when a larger moon split in two? New simulations put this theory to the test.

How (S)low Can You Go: Pulsar Edition

What causes some pulsars to spin much slower than others? Could it have to do with accretion from their birth environment?

Beginnings of a Branch

The Sagittarius stellar stream is split into two branches: why is that, and where did the stars in each branch come from?
