A black hole is the brightest object in the universe. Inside it, the force of gravity is so great that even light cannot escape from it. It would be logical if we did not see a black hole in the sky at all, but during the rotation of the hole, in addition to cosmic bodies, gas clouds are also absorbed, which begin to glow.

With our powers combined 😎

Chandra X-ray Observatory teamed up with the Webb telescope to create a new stunning composite image of the Tarantula Nebula. Chandra's X-rays (shown in royal blue and purple) identify extremely hot gas and supernova explosion remnants, while Webb reveals forming baby stars.

Unlike most nebulas in our Milky Way, the Tarantula Nebula has a chemical composition similar to that of conditions in our galaxy several billion years ago — when star formation was at its peak. For astronomers, this nebula is the perfect window into how stars formed in our galaxy in the distant past.

Jupiter can hold a thousand planets the size of our Earth. But at the same time, the Sun is larger than this giant, although if we compare our main luminary with other stars in the universe, it will turn out to be incredibly tiny. For example, the Big Dog star is one and a half thousand times larger than the Sun.
