GALAXY BRAIN 🧠

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? 🤔

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.
