Neutron stars are dense remnants of large stars. They are the collapsed cores of stars formed during a supernova explosion.
are dense remnants of large stars. They are the collapsed cores of stars formed during a supernova explosion.
After first capturing an image of VT 1137-0337 in 2018, it saw the neutron star again in 2019, 2020, and 2022. So we know it isn't just a transient radio burst of some kind.wind nebula. As the neutron star rotates, its magnetic field and energy beams sweep through the surrounding nebula, causing gas in the nebula to ionize and emit radio light.
On the face of it, that would make VT 1137-0337 less than twenty years old, but it could be a bit older. It's possible the neutron star existed in 1998, but the surrounding nebula was still dense enough to block radio light from reaching us.But given the rate at which supernova remnants expand, the fog should have cleared within 60 to 80 years, which means even the oldest estimates make it decades old, not centuries or millennia.
