A celestial body is a single cohesive structure that is bound together by gravity. Asteroids, moons, planets, and stars are all common examples of celestial bodies, but some of the ones out there are a lot more strange and unique. Sometimes the celestial bodies that are discovered can be so strange, that it actually reshapes what scientists think is possible about the universe and the way it works.
The Black Widow Pulsar
This pulsar weighs as much as two suns but is only the width of Washington DC. It’s an eclipsing binary millisecond pulsar discovered in 1988. It orbits a brown dwarf companion with a period of 9.2 ours, with an eclipse period of of around 20 minutes. The black pulsar steals energy from a neighbouring star. The pulsar gains more energy this way which makes it spin faster, but eventually strips the star of it’s material until it eventually disappears. Astronomers have found 18 black widows within the milky way galaxy.
