A planetary nebula is created when a star blows off its outer layers after it has run out of fuel to burn.

What is a planetary nebula? Select one: a. the disc of gas and dust surrounding a young star that will soon form a solar system b. a planet surrounded by a glowing shell of gas c. the ejected envelope of a red giant surrounding a stellar core remnant d. the bipolar jets ejected by a T Tauri variable

When a star with a mass up to eight times that of the Sun approaches the end of its life, it blows off its outer shells and begins to lose mass. Solution for Suppose a planetary nebula is 1 pc in radius. If the Doppler shifts in its spectrum show it is expanding at 22 km/s, how old is it?

And planets are definitely not a part of it. The name is a misnomer.SUBSCRIBE For a typical planetary nebula, its radius is of order 1 light year, or 9.5 x 10 12 km.
