There could be “dark main sequence” stars at the galactic center
Dark matter particle and antiparticle collisions could make some stars immortal. For a star, its initial mass is everything. It […]
Merger of two massive black holes is one for the record books
Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two […]

Simulations find ghostly whirls of dark matter trailing galaxy arms
“Basically what you do is you set up a bunch of particles that represent things like stars, gas, and dark […]
Milky Way galaxy might not collide with Andromeda after all
100,000 computer simulations reveal Milky Way’s fate—and it might not be what we thought. It’s been textbook knowledge for over […]
