The white dwarf was located in the Kinman Dwarf galaxy, in the constellation Aquarius.
Located 75 million light-years or 440,896,900,000,000,000,000 miles from Earth, the galaxy’s individual stars are too far away to directly observe.
Astronomers can, however, detect the signatures coming from the galaxy.
Between 2001 and 2011, they found evidence of a “luminous blue variable star” about 2.5 million times brighter than our Sun.
Stars of this type are known for being unstable and will occasionally shift in brightness and spectra.
