Dust Around a Giant Red Star Space Wallpaper
About this Image
An artist's impression of the dust surrounding the red giant star in this space wallpaper.During what's called the red giant phase, which can last 10,000 years, stars lose so much mass that all that remains are their leftover cores. They are also extremely bright during this time, releasing copious amounts of light in the form of photons that zoom outward in all directions.
