NGC 5882: A Small Planetary Nebula

NGC 5882 is a planetary nebula, captured here by the Hubble Space Telescope. These objects are not planets, but rather gas clouds surrounding stars, typically hundreds of light-years away. Planetary nebulae form when a star like our Sun completes fusion in its core and ejects an outer envelope of gas, usually about 10 percent of its initial mass. This gas shell fades over about 50,000 years.
