A recent discovery in the field of astronomy has shed light on the enigmatic behaviors of black holes, particularly focusing on their ability to consume surrounding stars. This article aims to explore the recent findings regarding a star-devouring black hole spotted by astronomers, the implications of this phenomenon on our understanding of the universe, and the methodology behind the discovery.
The Discovery of CSS161010
A team of astronomers led by Claudia Gutiérrez from the Institute of Space Sciences and the Catalina Sky Survey reported the detection of a fast and bright burst of energy emanating from a galaxy located approximately 500 million light-years from Earth. The burst, designated as CSS161010, was observed utilizing data from the Catalina Real-Time Transient Survey (CRTS), supplemented by observations from the Gran Telescopio Canarias. Intriguingly, this cosmic event was attributed to a small black hole engulfing a star, which opens up new avenues for studying stellar evolution and the violent interactions that can occur in the presence of such gravitational forces.

Understanding Black Holes
Black holes represent the remnants of massive stars that have succumbed to gravitational collapse at the end of their lifecycle. Their gravitational forces are so intense that not even light can escape once it crosses a boundary known as the event horizon. Consequently, while black holes themselves remain elusive and virtually impossible to observe directly, astronomers can infer their existence and behaviour indirectly through the gravitational effects they exert on nearby matter, such as gas clouds and stars.
The Nature of CSS161010
CSS161010 was marked by its extraordinary brightness, reaching peak luminosity just four days post-detection before undergoing a rapid decline. Subsequent analyses of the spectral properties of the burst unveiled significant findings:
- Hydrogen lines were observed indicating gas moving at velocities approaching 10% the speed of light.
- This rapid motion of material resembles phenomena typically associated with active galactic nuclei housing supermassive black holes, suggesting that even relatively small black holes can generate powerful events.
- The burst diminished in brightness by a factor of 900 over two months, implying a highly dynamic and rapidly evolving event.
Methodology of Discovery
The Catalina Real-Time Transient Survey (CRTS), launched in 2004, employs a network of telescopes based in Arizona to conduct wide-field surveys, effectively scanning vast stretches of the sky to identify transient astronomical events such as supernovae and asteroid activity. The revamping of previously detected events, like CSS161010, is a crucial aspect of this ongoing research.
