We discuss a new way to test the cosmological principle using X-ray studies of galaxy clusters in this Astrobite.
In this bite, we follow Betelgeuse’s rise to fame (and in magnitude).
A reanalysis of the cosmic microwave background data suggests a slightly more curved Universe than previously measured.
Wobbling pulsars might reveal gravitational waves from the distant past and future. Find out how in this Astrobite.
Today’s Astrobite opens a Russian doll analogy for the largest objects in our cosmos to help understand more about our universe.
