Are black holes really the cookie monsters of the universe?

SUMMARY

Scientists have observed a black hole named Swift-J 1644+57 consuming a star in a distant galaxy, marking one of the rarest astronomical events, occurring approximately once every 100,000 years per galaxy. This event highlights the unique characteristics of black holes, particularly their mass and compactness, which create an event horizon that prevents light from escaping. Neutron stars exhibit similar effects on a smaller scale, capable of ripping matter from other stars and forming their own accretion discs.

PREREQUISITES
  • Understanding of black hole physics and event horizons
  • Familiarity with neutron stars and their accretion processes
  • Basic knowledge of astronomical observation techniques
  • Awareness of the frequency of rare astronomical events
NEXT STEPS
  • Research the properties and behavior of black holes, focusing on Swift-J 1644+57
  • Study neutron star dynamics and their impact on surrounding matter
  • Explore the methods used in astronomical observations of distant galaxies
  • Investigate the statistical occurrence of rare astronomical events
USEFUL FOR

Astronomers, astrophysicists, and anyone interested in the dynamics of black holes and neutron stars, as well as those studying rare cosmic phenomena.

This is a public service:

1] Blurb: "For the first time, scientists spotted a black hole devouring a star in a distant galaxy. One of the rarest astronomical events, it's believed to happen only about once per 100,000 years per galaxy." That is the ENTIRE written content of the link.

2] It's a video "news" article.

3] It's content-free.

The BH is named Swift-J 1644+57 if anyone wants to read up on it.

clearwater, please, in the future supply an explanation, not just an inscrutable link.

FYI, a neutron star would induce similar effects on it's scale. They can and do rip matter from other stars and have their own accretion discs. The only thing special about a black hole is that they are more massive and compacted into an area of space small enough so it that causes them to have an event horizon where light cannot escape once inside it.
