Astronomers Discover a Rare, Lonely Neutron Star
Astronomers have discovered a peculiar neutron star hanging out by itself.
The star, E0102, is located 200,000 light years from Earth.
Neutron stars are the dense core of stars that have collapsed and gone through a supernova explosion. NASA says E0102 is rare because it has a low magnetic field and no stellar companion.
The images are from NASA’s Chandra X-ray Observatory and the European Southern Observatory’s Very Large Telescope in Chile.
The observatories found that the star is dominated by a large ring-shaped structure, connected to the blast wave of the supernova. A smaller ring expands more slowly than the blast wave, giving the effect of a “celestial bull’s eye” as seen in the video above.
