Black holes and the stars that feed them dance in a NASA film.

Some of the closest black holes to Earth, as well as the stars that feed them, are depicted in a new NASA animation.

In both our Milky Way galaxy and the adjacent Large Magellanic Cloud, the image exhibits 22 X-ray binaries.

The black hole is portrayed as a black dot in the center of an orange-red accretion disc, according to a NASA statement accompanying the film, while the star is depicted as a bluish- or yellowish-white sphere scaled to match its size.

A black hole is a region of space where gravity is so strong that even light cannot escape. When a star goes supernova, it shoots massive amounts of matter into space before folding in on itself and collapsing. (Don’t worry: turning our sun into a black hole would take about 20 times its actual mass.)

An X-ray binary’s black hole can gather energy from its star in two ways.

According to Scientific American, a stream of gas might flow directly from the host galaxy’s star into the black hole, whirling “like water down a drain.”

Scientists are unable to study black holes directly using telescopes because they do not emit light. Matter going into a black hole, on the other hand, gradually heats up and glows, finally emitting X-rays. This graphic is built around those X-rays.

Other stars produce stellar winds, which are “fast-flowing streams of particles emitted from a star,” according to Hubble Space Telescope staff. A black hole’s tremendous gravitational attraction permits it to gobble up some of this matter.

Although the visualization depicts a variety of black holes, these objects are shown as being far larger than they are in contrast to their companion stars and accretion disk.

Consider Cygnus X-1, the first-ever confirmed black hole. The event horizon, the planet’s surface, is only around 77 miles (124 kilometers) broad.

The depiction, on the other hand, depicts Cygnus X-1 as much larger, more in accordance with the black hole’s mass than its volume.

The viewing angles in the image reveal how we can see the systems from Earth, but the orbital velocity is 22,000 times quicker than what is viewed.
