Neutron stars are dense remnants of large stars. They are the collapsed cores of stars formed during a supernova explosion. While we know generally how they form, we are still learning how they evolve, particularly when they are young. But that’s starting to change thanks to large sky surveys, which have allowed astronomers to observe … Read more

A new analysis of one of the most famous explosions in the cosmos has revealed a curious asymmetry. Part of the inner nebula of the Cassiopeia A supernova remnant is not, astronomers have found, expanding evenly. Something has caused a section of the cloud to move, not outwards with the rest of the material, but … Read more
