In the Triangulum Galaxy, over the course of a hundred thousand years, three supernova exploded from the same star cluster. The remains of these explosions have expanded into a trio of giant bubbles nested within each other.
Recently, several supernovae have been observed that do not fit in any of the known categories. These Calcium-rich supernovae are challenging to explain, but in this astrobite you read that they are likely the result of an expelled merger.
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!
A cosmic orchestra of nearby supernova explosions created the ‘Local Bubble’ all around us. Could these stellar super-bombs have influenced Earth’s climate and even human evolution?
In today’s astrobite, a group of astronomers experiences déjà vu while studying gravitational lensing.
Today’s paper explores the galactic homes of superluminous supernovae — some of the brightest explosions in our universe.
