As reported by Media Indonesia Astronomers have accurately measured the distance between the Earth and the black hole for the first time. Apparently, the distance is closer. The researchers determined that the black hole called V404 Cygni is located 7800 light years from Earth. This means that more than half the distance previously assumed. This puts the black hole is relatively close to Earth. Just so you know, the distance to the central black hole galaxy about 26,000 light-years away.
Measurements are more accurate distance allows scientists to paint a better picture about the evolution of black holes evolve. "For example, we hope to answer questions about the matter the difference between a black hole that has evolved directly from the collapse of a supernova star without a black hole that has evolved through the supernova and from temporary secondary star.
Jonker and his team know the distance of Earth to the V404 Cygni to measure radio emissions from dying stars that are exploited black hole. As the outer layers of the star being sucked by a black hole, the gas that formed around the hot plasma disk around the black hole before it disappears. This process is a lot of X rays and radio waves. The team used a radio telescope called the High Sensitivity Array.
