![]() ![]() ![]() Spaghettification and the "Point of No Return" One question that continues to intrigue scientists and science enthusiasts alike is: What actually happens when something gets too close to a black hole? Or, even though there are no black holes within human reach, what would happen if one of us got a little too close to a black hole? Instead, astronomers primarily look for the ways that black holes influence and distort matter around them. This is, in part, because light can't escape from a black hole, so they cannot be observed directly with telescopes. While scientists have dramatically improved our understanding of black holes since that first detection, these objects remain quite mysterious. Now astronomers have a growing understanding of these strange gravitational powerhouses that form from the collapsed cores of dying stars. Observatories detected X-rays coming from Cygnus X-1, which we now know is a black hole in orbit around a regular star in our own Milky Way galaxy. However, it wasn’t until 1964 that astronomers found strong evidence of a black hole for the first time. Scientists have theorized about the existence of black holes since the 18th century.

To take into account background integral contributions).Seen nearly edgewise, the turbulent disk of gas churning around a black hole takes on a bizarre double-humped appearance.
