Hot Stars Spin Sideways

Most cool stars spin nicely aligned with their planets. So why do their hot counterparts tumble in nearly random directions?

Billions of years ago, small galaxies may have had cores packed with dark matter. What would these galaxies look like today?

spiral galaxy NGC 3432

Astrobites reports on simulations of the circumgalactic medium, a reservoir of gas that helps regulate a galaxy’s ability to form stars.

Cassiopeia A supernova remnant as seen by JWST

Thanks to JWST, the supernova remnant Cassiopeia A has a beautiful new portrait that has allowed astronomers to study the connection between molecules, dust, and supernovae.
