www.astrobin.com/p8xvh2/

This bright nebula is part of the Barnard 347 nebula known as Butterfly Nebula.

The Butterfly Nebula, also known as NGC 6302, is a striking planetary nebula located in the constellation Scorpius. This celestial beauty earned its name due to its distinctive appearance resembling a butterfly with outstretched wings. The nebula is the result of a dying star that has shed its outer layers, creating a cocoon-like structure illuminated by the central remnant—a hot, dense stellar core known as a white dwarf.

At the heart of the Butterfly Nebula lies one of the hottest stars known, with temperatures reaching over 200,000 degrees Celsius (about 360,000 degrees Fahrenheit). The intense ultraviolet radiation emitted by this central star energizes the expelled gas, causing it to fluoresce and produce the nebula's colorful glow. The complex and intricate patterns within the nebula are formed by a combination of ionized gases and intricate dust formations, creating a visually captivating celestial spectacle.
