Astronomers Catch Black Hole Spewing Matter After Feeding
Astronomers using the Very Large Telescope have observed a binary black hole system, Swift J1727.8−1613, discharging matter after consuming a companion star. This observation provides new insights into the complex life cycle of black hole feeding and eruption.
Why it matters
Understanding the mechanisms of black hole consumption helps scientists solve fundamental mysteries regarding the evolution of celestial objects.
Black holes are some of the most awe-inspiring and mysterious celestial objects in the universe. This is primarily because astronomers still don’t understand the underlying mechanisms that drive black holes, including its formation, evolution, and end. As their name implies, black holes can’t be viewed directly since they blend into the background of the vastness of space. Therefore, astronomers are limited to “seeing” black holes when they consume other celestial objects, most notably stars. When this happens, the astronomers see the light from the star being violently consumed by a nearby black hole in a spectacular display. However, astronomers are still puzzled regarding what happens after the consumption.
