Same ol’ same ol’? Galaxy Clusters across Cosmic Time
X-ray studies of galaxy clusters tell us how the extremely hot gas is distributed within these gigantic structures. Looking at these clusters across different redshifts, what does one find?
Bulges are red, disks are blue…
…or are they? The color-mass diagram for galaxies can tell us a lot about galaxy evolution, and today’s paper reports what this diagram looks like at high redshifts.

Investigating One of the Strongest Starbursts in the Universe
Today’s astrobite explores one of the most extreme distant galaxies: a dusty, star forming galaxy at redshift 5.7 which has been found to have one of the highest star formation densities of any known galaxy in the Universe. But what causes this? Does it contain an active galactic nucleus?
Bright Line that Goes a Long Way
The biggest and the brightest Lyα nebula is discovered! What can we learn from this giant?
Finding the missing light in the universe … from faint galaxies ?
In today’s guest post, Ziad Sakr discusses the role of ultrafaint galaxies in cosmic reionization.
