science π Helix Nebula shows our Sun's future π
The Helix Nebula, a vast shell of glowing gas, was revealed by NASA's Image of the Day. It is located about 650 light-years from Earth in the constellation Aquarius. The structure spans a ring nearly three light-years across and features thousands of comet-like filaments. This nebula shows how Sun-like stars eventually shed outer layers, exposing a white dwarf core. It serves as a preview of what could happen to our own solar system in the future.
