The ominous image of the Snail nebula taken by the Spitzer Space Telescope clearly shows the infrared radiation of the Snail nebula (NGC 7293). This nebula is well studied, although it is located at a great distance from our planet. It is 700 light-years away, it is located in the constellation Aquarius.
It is enveloped in a gas-dust shroud, its diameter is two light-years. The white dwarf located in the center of the nebula is an excellent example of a planetary nebula – what a Sun-type star will turn into at the final stages of evolution.
