Astrobites interviews Sean Carroll, one of the leading theoretical cosmologists of our time, about our universe, his new book and everything in between.
What can aLIGO tell us about the earliest stars? Read today’s astrobite to find out!
New supernovae measurements and precise distance calculations lead to an interesting conflict in cosmological parameters in the universe, depending on whether a tool is used to probe the local or the distant universe. Read on to find out how!
Our Sun’s ancestors are thought to form out of the primordial composition of the early Universe, almost pure hydrogen and helium. How likely are we to observe such stars?
This article explores the utility of galaxy clusters as a probe for precision cosmology, by reviewing some of the seminal literature in the field. Somewhere along the way, a symphony is heard.
By searching for Lyman-alpha emission lines, astronomers have confirmed one of the most distant galaxies yet, helping shed light on the very earliest galaxies and their formation.
