Glowing Eye Nebula
This Hubble Space Telescope shows the highly unusual planetary nebula, NGC 6751. The nebula resembles giant eye, giving rise to its nickname "Glowing Eye Nebula". It is a cloud of gas ejected several thousand years ago from the hot star visible in its center. Planetary nebulae are named for their round shapes as seen visually in small telescopes. They are shells of gas thrown off by stars of masses similar to that of our own Sun, when the stars are nearing the ends of their lives. NGC 6751 is located 6,500 light-years away from Earth in the constellation Aquila.
