If a star passes too close to a black hole, it can be torn apart.

For 20 years, a team of astronomers observed a star at the center of our galaxy orbiting a black hole.

The star has now got close enough to the black hole for “gravitational redshift” to occur which is where the star’s light loses energy as the black hole’s gravity intensified.
