Infrared Universe: Helix Nebula - Webb
2018年11月12日 · Stars like our Sun end their lives by casting off their outer layers, briefly forming a spectacular "planetary nebula" like the Helix Nebula. In visible light, we see the glow of hot gases illuminated by a hot, compact core, known as a "white dwarf."
Helix Nebula - Wikipedia
The Helix Nebula is an example of a planetary nebula, formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. Gases from the star in the surrounding space appear, from Earth's perspective, a helix structure.
