Cosmic Weight Watchers
The disc in the picture is made up of material leftover from the birth of a star. The disc contains enough to build all eight planets of our Solar System, and still have leftovers! In fact, it has enough material to make 50 Jupiter-sized planets— each one big enough to fit the Earth inside 1000 times!
