Quasar

A Quasar is a specific type of astronomical object formed by matter falling into a super-massive black hole.
The resulting energy is released as X-rays in all directions. However, the X-ray release is most intense directly above or below the galactic plane.

• Observed from this view, the resulting bright object is known as a Quasar.

Fun Fact:

Star Trek's apparent definition of quasars differs from what is established as such in 21st century real-world science. In fact, "quasars" are always associated with supermassive black holes in the centers of young galaxies, and could therefore not occur within the Milky Way. The quasars, or "quasar-like objects", mentioned and shown in Star Trek more closely correspond to what real-world science calls microquasars.
