NASA has shown what the Caldwell 22 Nebula, also known as the Blue Snow, looks like. The NASA Comics Agency has published a picture of a distant nebula, which is located in the constellation Andromeda.
The photo was posted on NASA’s Instagram page. This beautiful nebula is reportedly located about 2,500 light-years from Earth. Blue Snow is a planetary nebula in the constellation Andromeda. It is quite popular among astronomy enthusiasts because it can be seen even through a small telescope.
Dawns are nuclear furnaces that convert hydrogen to helium for most of their lives. Massive stars have a fiery fate, exploding like supernovae, but medium-mass stars such as the Sun swell, turning into red giants when they run out of fuel.

A Blue Snowball From Across the Universe! Caldwell 22, also cataloged as NGC 7662 and nicknamed Blue Snowball Nebula, is located about 2,500 light-years from Earth. It represents a stage in evolution that stars like our Sun undergo when they run out of fuel. Stars are nuclear furnaces that spend most of their lives fusing hydrogen into helium. Massive stars have fiery fates, exploding as supernovae, but medium-mass stars like the Sun swell to become red giants as they exhaust their fuel. Credit: NASA, ESA, and A.
