Astronomers Find a Brand new Pulsar That's Probably Less Than 14 Years old - by BrianKoberlein
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 a neutron star that could be little more than a decade old.
The neutron star in question is known as VT 1137-0337. It is in a dwarf galaxy about 400 million light-years away, and it was first seen in 2018 as part of the Very Large Array Sky Survey . VLASS is a seven-year project to create a radio map of the sky. When finished it will have mapped about 80% of the sky over the course of three separate runs. After first capturing an image of VT 1137-0337 in 2018, it saw the neutron star again in 2019, 2020, and 2022.
