Hot new James Webb Space Telescope image just dropped. Like, *really* hot.
This is just a tiny portion of the #HelixNebula. It is the end result of a life stage of #stars with about the mass of the Sun. Like people, stars are born, live and die. The Helix Nebula represents old age for Sun-like stars, after the exhaust their nuclear fuel. The stars shed their outer layers into the surrounding space and contract to become white dwarfs, a kind of shell or husk of their former selves.
What you're seeing here are thousands of so-called 'cometary knots', each about the size of our Solar System. They're only 'cometary' in appearance, forming tails behind them. Note that they all point in a common direction, toward the white dwarf star that is outside the frame toward the top. The knots are clumps of material rich in molecules, shed by the dying star before it entered its current phase. Now they are blasted by the intense radiation coming from that star, which shapes their appearance.
As the European Space Agency puts it: "Its intense radiation lights up the surrounding gas, creating a rainbow of features: hot ionized gas closest to the white dwarf, cooler molecular hydrogen farther out, and protective pockets where more complex molecules can begin to form within dust clouds. This interaction is vital, as it’s the raw material from which new planets may one day form in other star systems."
