This is a
Black
Hole which is emitting energy, generally because it is
absorbing matter from a nearby source. As a black hole pulls
matter into it, an accretion disc will form around an equator, reaching
phenomenal temperatures and releasing really substantial amounts of
energy. The location of an emissive black hole will be obvious to
anyone in the general neighborhood with any abilities in astronomy in
any wavelength. Surviving in the vicinity of such a black hole,
however, will be quite difficult.
