Supernova hunters have been busy: SN 2024ggi is the second nearby supernova in less than a year. What do archival observations tell us about this supernova’s progenitor star?

Simulations suggest that black holes could have grown to supermassive size with the help of young star clusters in the early universe.

A pair of nearly identical fast radio bursts from different sources gives a hint to the cause of these powerful radio flashes.

Hot Stars Spin Sideways

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

Astrobites reports on “little red dots” in the early universe and how to use X-rays to determine if these galaxies host massive black holes.
