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.
NGC 1514: When William Herschel saw the bright star in the heart of this planetary nebula, he realized that he wasn't looking at clusters but through gas and dust. As a result, he coined the name planetary nebula, because they shared the coloration of the recently discovered Uranus.Saturn Nebula NGC 7009: Located in the constellation Aquarius, the Saturn Nebula, or NGC 7009, has a bright central star surrounded by a football shaped array of gas and dust.Stingray Nebula (Hen-1357): The youngest known planetary nebula, Hen-1357 is as large as 130 solar systems.GC 1514: When William Herschel saw the bright star in the heart of this planetary nebula, he realized that he wasn't looking at clusters but through gas and dust.
