Pulsar lost colony black hole11/2/2022 ![]() ![]() The system is HR 6819, which was under study by the Rivinius team as part of an effort targeting double-star systems. While the black hole is invisible, the two stars in HR 6819 can be viewed from the southern hemisphere on a dark, clear night without binoculars or a telescope. This map shows most of the stars visible to the unaided eye under good conditions and the system itself is marked with a red circle. Image: This chart shows the location of the HR 6819 triple system, which includes the closest black hole to Earth, in the constellation of Telescopium. The system is located in Telescopium, its stars viewable without binoculars or telescope on a clear southern hemisphere night. This is, in other words, a triple system, and one that can be seen with the naked eye at that. A long way, to be sure, but the closest ever found to our planet.Įvidence for the object comes from the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile, deduced by a team of astronomers led by Thomas Rivinius from observations of two companion stars. Thus the just announced discovery of a black hole 1,000 light years from Earth. But we’re also learning through gravitational wave studies about their interactions and have begun to find black holes closer to home. We’re learning about the black holes at the center of many galaxies even as we’re just beginning to catalog the location of smaller ones elsewhere. Black holes are such exotic objects that they somehow suggest great distance. ![]()
