Notable features | A extragalactic Pulsar Wind Nebula |
VT 1137-0337 is a extragalactic pulsar wind nebula (possibly a magnetar nebula[1]) that is located 395 million light years away from planet earth in the dwarf galaxy named SDSS J113706.18-033737.1, a galaxy going through a burst of star formation. It was created through the supernova of a massive star just 14-80 years ago.[2]
Formation
VT 1137-0337 was formed 14 to 80 years ago when a massive star went supernova leaving behind a supernova remnant and a young pulsar type fast spinning neutron star.[2]
Neutron star
The neutron star left at the center of VT 1137-0337 is fast spinning pulsar type neutron star that has a strong magnetic field creating charged particles travelling at the speed of light in the surrounding space creating a strong radio emission.[3]
Discovery
The nebula VT 1137-0337 was spotted by using the Very Large Array Sky Survey (also called VLASS).[4]
