This six-panel illustration of a tidal disruption event around a supermassive black hole shows the following: 1) A supermassive black hole is adrift inside a galaxy, its presence only detectable by gravitational lensing; 2) A wayward star gets swept up in the black hole's intense gravitational pull; 3) The star is stretched or "spaghettified" by gravitational tidal effects; 4) The star's remnants form a disk around the black hole; 5) There is a period of black hole accretion, pouring out radiation across the electromagnetic spectrum, from X-rays to radio wavelengths; and 6) The host galaxy, seen from afar, contains a bright flash of energy that is offset from the galaxy's nucleus, where an even more massive black hole dwells.

What is the Mystery Object in the Milky Way? A Neutron Star or a Black Hole?

In this video, we explore the nature and significance of a new mystery object in the Milky Way that could be either the heaviest neutron star or the lightest black hole ever seen. This object was discovered by astronomers using a radio telescope in South Africa, and it is orbiting a rapidly spinning neutron star or pulsar in a cluster of stars. The mass of the object is between 2.09 and 2.71 solar masses, which is right in the lower mass gap, a range of masses where very few neutron stars or black holes have been detected. This gap is thought to be a result of the different ways that massive stars die and collapse, depending on their initial mass and composition. But the exact mechanism and the boundary between neutron stars and black holes are still unclear and debated. So, what is the mystery object? Is it a very heavy neutron star or a very light black hole? And why does it matter? Watch this video to find out.
