The Hyades Disperse Cluster, just 150 light years away, is believed to have the closest black hole ever detected.
An open cluster is a sparse collection of hundreds of stars that were born at the same time, and all their stars have common chemical properties.
Located in Taurus near Orion's three stars, Hyades is the closest open cluster to the solar system and can be seen with the naked eye throughout winter.According to "캡포탈," it consists of about 500 stars and is also called "the face of a bull."
Detects the closest black hole to Earth
Several small black holes may exist in the Hyades cluster, according to a paper published in the Royal Astronomical Society (MNRAS).It will be the closest black hole ever detected.
Black holes cannot be observed directly because they do not emit light.The research team then simulated the motion and evolution of stars in the Hyades cluster and compared the results with their actual location and speed.
The location and speed of the stars were updated by the European Space Agency's (ESA) astronomical observation satellite Gaia.Gaia is measuring the motion of billions of stars with high accuracy, aiming to create a three-dimensional (3D) map of the Milky Way galaxy.
There are two or three black holes
The results of this study suggest that there are two to three small black holes in or near the Hyades cluster.Stefano Torniamenti, a Ph.D. researcher at Padova University in Italy, explained, "In this simulation, both mass and size of the cluster were consistent only if some black holes were assumed to exist in the center of the Hyades cluster."
The closest black hole to the solar system was the Gaia BH1, which is 1,560 light-years away in the direction of Snake.Snakes are visible throughout summer in the northern hemisphere (winter in the southern hemisphere).
The study was jointly conducted by Padova University, the Institute of Space Science (ICCUB-IEEC), Cambridge University, the European Southern Astronomical Observatory (ESO), and Zhongshan University in China.
