Above and Beyond: Planetary Nebula NGC 2440

This planetary nebula, NGC 2440, is the colorful "last hurrah" of a star like the Sun. The dying star has cast off its outer layers of gas and is now much smaller than the Sun.

(DESCRIPTION) 
 A two-lobed pink and orange nebula. 

Text, PLANETARY NEBULA NGC 2440. This planetary nebula is the colorful "last hurrah" of a star like the Sun. The dying star has cast off its outer layers of gas and is now much smaller than the Sun. 

Ultraviolet light from the star's hot core heats the gas and makes it glow. 

The nebula's bow-tie shape suggests the star might have released its gas in multiple bursts and in different directions.
