This artist’s rendition shows binary system VFTS 243, which is composed of a black hole and a blue star that has 25 times the mass of the Earth’s sun. A team of international experts announced the discovery of a dormant stellar-mass black hole in the Large Magellanic Cloud, a galaxy that neighbors the Milky Way.

The Event Horizon Telescope captured the first direct visual evidence of the presence of the Sagittarius A* supermassive black hole, which sits at the center of our Milky Way galaxy. The image was released to public on May 12. Photo: NASA/VCG

An artist’s rendition of what the center of a galaxy might look like. The image aims to depict the Messier 77's active galactic nucleus, the mass of dust and gas that surrounds a supermassive black hole at the center of that galaxy. Photo: European Southern Observatory/VCG

An illustration, which was released on Oct. 12, 2020, depicts a star getting stretched toward a supermassive black hole during a “tidal disruption event,” an astronomical phenomenon that occurs when a star gets close to a supermassive black hole. Photo: European Southern Observatory/VCG

This image released Oct. 6, 2020, shows the orbits of stars around the supermassive black hole at the heart of the Milky Way. Photo: European Southern Observatory/VCG

On July 11, 2019, the European Space Agency released an artist’s depiction of the peculiar thin disc of material circling the supermassive black hole at the heart of the spiral galaxy NGC 3147, which is about 130 million light-years from Earth. Photo: European Space Agency/VCG

This image generated from a computer simulation shows the collision of two black holes, an event that the Laser Interferometer Gravitational-Wave Observatory detected for the first time in August 2017. Photo: Caltech/VCG

In this image released by NASA on Nov. 4, 2013, jets generated by supermassive black holes at the center of galaxies transmit huge amounts of energy across great distances. Photo: NASA/VCG

The image released on July 13, 2009, shows the NGC 1097 galaxy with an eye-like object at its center. The “eye” of this galaxy, which is 50 million light years away, is a monstrous black hole surrounded by stars. Photo: NASA/VCG
