Planetary Nebula NGC 2440
Planetary nebula NGC 2440 is a relic of a star once like our Sun that has cast off its outer layers of gas, forming a colorful cocoon around the star's remaining core.
Our Hubble Space Telescope spotted this planetary nebula in the constellation of Orion. It's really a vast orb of gas in space, with its aging star in the center... but what does it look like to you? ๐ค
When stars like the Sun grow advanced in age, they expand and glow red. These so-called red giants then begin to lose their outer layers of material into space. More than half of such a star's mass can be shed in this manner, forming a shell of surrounding gas. At the same time, the star's core shrinks and grows hotter, emitting ultraviolet light that causes the expelled gases to glow.
Wow - the visible star at the center of the planetary nebula is an A-type giant star. It's the companion of the white dwarf which spawned the nebula itself. (Loved the pic so much I had to read about the object a little).
