About it
A planetary nebula is a glowing shell of gas puffed off by a dying star like the Sun. The hot little star left at the middle, a white dwarf, lights up the gas so it glows. The name is an old mistake: through early telescopes these round clouds looked a bit like planets, but they have nothing to do with planets.
This one is shaped like the Ring Nebula, about 2,500 light-years away. Tap it and the star at the middle flares and blows out a thin, bright ring of gas; when it reaches the main ring, the ring glows brighter and is pushed outward, then settles.
