Indeed, gravity pulled them together, packing them into a hot cosmic stew that together would eventually coalesce to form our solar system. The nebula here resides 20,000 light-years away in the constellation Carina. Stars are held together by the force of gravity. From 1 and 2 we are actually transferring stardust. âWorlds beyond the solar system.â Science News for Students.

Similarly, every rock, plant, animal, scoop of seawater and breath of air owes its existence to distant suns. New analyses indicate it is furiously transforming gas and dust into new stars more than 2,000 times faster than occurs in our own Milky Way. It spans about 100 light-years across. previous understanding earlier than analyzing this article was the belief that we're constituted of Stardust. Shortly after the universe formed, this galaxy churned out stars at an amazing speed. All of this element-building âtakes time,â says Pilachowski. Herschel: Quang Nguyen Luong & F.
