Things that can make people feel shocked are generally things that will make people realize that they are very small. What can talk about? A sense of smallness? Things, then you have to talk about black holes that can easily tear stars. Recently, astronomers from the University of Birmingham in the United Kingdom released the results of an observation study, which clearly recorded the whole process of black holes devouring stars with time-lapse pictures. In the video, a star passes by the black hole, but it is pulled and torn by the powerful tidal force because it is too close to the black hole.

Then it becomes a slender stream of matter, and eventually a considerable part of the whole star falls into the black hole, during which a bright flash breaks out. The mass of this star is not small, similar to that of the sun, but about half of it is swallowed up by black holes. Just a little bit will be completely swallowed up by black holes. This shocking scene took place in deep space 250 million light years away from the earth.

Light-year is the distance that light travels for one year, which means that the picture of black holes devouring stars that we have observed now occurred 250 million years ago. 250 million years ago, when there were no humans on the earth. This idea makes people feel that their life is so short and insignificant, is it just a poem of stone? Sending a ephemera to the ground is a drop in the bucket? . Most of us ordinary people have not participated in and studied too profound astronomical knowledge and practice. In the face of such a scene, we can only be awed and shocked.

Of course, the picture of a black hole tearing a star we see is not recorded directly with a lens like ordinary documentary photography. Because deep space objects are too far and too dark for us. The cone cells responsible for color perception of human eyes cannot effectively identify the color of dim objects. Therefore, most astronomical images/images we see in the media are actually processed with raw data, rather than the original film presentation.
