(1) The object is being stimulated by jets from a rapidly spinning (about thirty times a second) neutron star called a pulsar .

(2) Black holes, the cosmic microwave background, pulsars , neutron stars, gravitational lenses, gravity waves - these are just a few of the phenomena that would make no sense without general relativity.

(3) The Universe has its own heavenly sounds, such as pulsars , planetary magnetospheres and solar winds.

(4) These emanations come from rapidly spinning neutron stars called pulsars - rotating beacons that periodically send energy in the direction of the earth.

(5) I read up on interstellar objects and astrophysics and studied quasars, pulsars and supernovas, but my main focus was black holes.
