El agujero negro de la Vía Láctea

The video explains that most galaxies, including ours, have a central black hole formed from collapsing stars. These black holes are so dense that light cannot escape their gravity. Using powerful telescopes, astronomers observe stars near the Milky Way's center, revealing their high-speed orbits around a massive object, believed to be the black hole Sagittarius A. This black hole is 26,000 light-years away and 4 million times heavier than the Sun. Despite its mass, it remains dormant, with the galaxy revolving around it.

What happens to large stars that leads to the formation of black holes?

• They expand and cool down.

• They explode into supernovae.

• They collapse in on themselves.

• They merge with other stars.
