| 説明 | Stars come in an extraordinary range of sizes. This illustration depicts one of the most colossal, VY Canis Majoris. If placed in the middle of our solar system it would engulf all the planets out to Saturn's orbit. This monster, appropriately called a red hypergiant, is as bright as 300,000 Suns. Yet it is so far away that, 200 years ago, it could be seen only as a faint star in the winter constellation of the Great Dog. Since then, it has faded and is no longer visible to the naked eye. Astronomers used Hubble to get a close-up look at the star and discovered the reason for the dimming. The star is expelling huge clouds of dust in the final stages of its life. Eventually, the bloated star may explode as a supernova, or may simply collapse and form a black hole.Credit: NASA, ESA, Roberta Humphreys (UMN), Joseph Olmsted (STScI)For more information, visit: hubblesite.org/contents/news-releases/2021/news-2021-009Find us on Twitter, Instagram, Facebook and YouTube |
