Скачать или смотреть Hubble Reveals: Who Brutally Attacked the Andromeda Galaxy?

This is the Hubble telescope, a photo that has just been sent back; after scientists finished looking at it, they collectively fell silent. Inside this photo are hidden 200 million stars; every single one is dozens of times bigger than the Sun; and all of them come from the Andromeda Galaxy that is 2.5 million light-years away from us. Even more terrifying is that this galaxy is charging toward Earth at a speed of 110 kilometers per second, and 4 billion years later it will collide head-on with the Milky Way. But you absolutely cannot imagine that the Andromeda Galaxy had actually already been covered in wounds long ago. Scientists found, on it, two gigantic dust rings, like ripples in a pond. This means it had once been struck viciously. Who was the murderer?
