Bedtime Astronomy

Millions of black holes may roam the Milky Way undetected, but finding one without a companion is a major challenge.

Astronomers searching Gaia data for isolated black holes within 50 light-years of Earth found candidates that failed follow-up checks using radio and infrared observations. Why are these invisible cosmic objects so difficult to detect, and what will it take to finally find one nearby?

New Hubble Space Telescope observations are challenging scientists’ understanding of how the early universe became transparent. Surprisingly, galaxies with the fastest winds appear to trap more radiation rather than release it.

The findings suggest that young stars may have helped clear the primordial hydrogen fog before supernova explosions reshaped these galaxies. Could this change what we know about the universe’s earliest evolution?
