The Ring Nebula is about 2,000 light-years from Earth and measures roughly 1 light-year across. Located in the constellation Lyra, the nebula is a popular target for amateur astronomers. Previous observations by several telescopes had detected the gaseous material in the ring's central region. But the new view by Hubble's sharp-eyed Wide Field Camera 3 shows the nebula's structure in more detail.
Nebulae are often star-forming regions, such as in the Pillars of Creation in the Eagle Nebula. In these regions the formations of gas, dust, and other materials clump together to form larger masses, which attract further matter, and eventually will become massive enough to form stars.mission nebulae, such as the Eagle Nebula, are vast, glowing clouds of ionised hydrogen and dust where stars are born. Others, such as planetary nebulae, are the bright shells of gas shed by dying stars. Despite their name, planetary nebulae have nothing to do with planets.
