It was only noticeable to the researchers once they saw a star with peculiar motion among so many other stars that weren’t behaving the same way. Black holes emit X-rays when they gobble up surrounding matter or create gravitational waves when they crash into one another or collide with dense neutron stars.īut all black holes are not created equal, and this one is smaller than some of the others astronomers have detected. Because no light can escape, black holes are. Some black holes are a result of dying stars. This compression can take place at the end of a star's life. The strong gravity occurs because matter has been pressed into a tiny space. There is no danger of the Earth (located 26,000 light years away from the Milky Ways black hole) being pulled in. A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. While black holes are tricky to spot, they tend to give away their otherwise invisible presence by their actions. Since this black hole already weighs a few million times the mass of the Sun, there will only be small increases in its mass if it swallows a few more Sun-like stars. Record-breaking 'tsunami' of gravitational waves detected Supermassive black holes at the hearts of galaxies are thought to form through the merging of smaller, yet still massive black holes, such as the ones depicted here. Two black holes are entwined in a gravitational tango in this artist's conception. Based on observations from telescopes on Earth and in space, we know that some black holes grew to be a billion times the mass of the sun just one billion years.
