The Euclid space telescope launched just over a year ago, and is already returning great science! In today’s bite, it’s looking at stars in the Perseus cluster that don’t belong to any galaxy.
Protocluster Galaxies Love to Talk to Their Neighbors
Galaxy evolution is affected by a complex web of neighborhood politics between nearby galaxies. Today’s authors show that it’s the closest galaxies that matter the most in a galaxy protocluster!
Sloshing in the Universe’s Biggest Bathtub
The centers of galaxy clusters are energetic and exciting places. Today’s paper explores why Abell 2495 is particularly exciting – it’s sloshing around!

Cool, Relaxed, but Way Out of Its Lane: The Most Distant Cooling-Flow Galaxy Cluster Yet Observed
Galaxy clusters like to relax, but it takes most of them a long time to get there. In today’s paper, the authors have found an exception to that rule!
A Galactic Prison Break: Tracing Lyα Escape at High Redshift
Astrophysics is a lot like life in that sometimes the journey matters more than the destination. In today’s paper, which looks at the Hydrogen Lyman-α spectral line in a high-redshift protocluster, that’s absolutely the case!
