Z 36-24 is in the COSMOS field, one of the most studied patches of sky. NSF–DOE Rubin Observatory's deep view reveals hundreds of thousands of galaxies here. By repeatedly observing the sky, Rubin will help scientists track huge populations of active galaxies over time.🔭🧪

And Z 36-24 has a very active center! 💥 At its heart is a supermassive black hole feeding on surrounding material. This makes the galaxy an “active galactic nucleus,” or AGN. Studying AGN helps scientists understand how black holes and galaxies evolve together.🔭🧪

We can't see inside stars — we really can only observe the light coming from their surfaces. But when a star changes in brightness, it can reveal clues about what's happening deep inside. That's why scientists are so interested in variable stars! 🔭🧪

NSF–DOE Rubin Observatory @rubinobservatory.org · 24/09/2026

Imagine looking up and watching a star suddenly lose 99% of its light. These stars are a rare type of variable star called an R Coronae Borealis. They suddenly puff out huge clouds of dust, blocking nearly all their light for months before returning to normal.🔭🧪
