Making of an Active Galactic Nucleus
In light of new observations, the traditional dusty-torus picture of active galactic nuclei may need revision.
A Trio of Supernova Fossils
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.
The merger of two castaways
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.
Conflicts between Expansion History of the Local and Distant Universe
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!
Grand Fireworks from the Local Super-Bubble
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?
A Blast from the Past: Forecasting Supernova Refsdal
In today’s astrobite, a group of astronomers experiences déjà vu while studying gravitational lensing.
