One of the most intriguing predictions of Einstein\u2019s general theory of relativity<\/a> is the existence of black holes: astronomical objects with gravitational fields so strong that not even light can escape them.<\/p>\n\n

When a sufficiently massive star runs out of fuel, it explodes and the remaining core collapses, leading to the formation of a stellar black hole<\/a> (ranging from 3 to 100 solar masses).<\/p>\n\n

Supermassive black holes also exist in the centre of most galaxies. These are the largest type of black hole, containing between one hundred thousand and ten billion times more mass than our Sun. <\/p>\n\n

So far, astronomers have captured images of two supermassive black holes: one in the centre of the galaxy M87, and the most recent in our Milky Way (Sagittarius A*<\/a>).<\/p>\n\n

This animation shows a size comparison between these two giants:<\/p>\n\n
