APOD: The Butterfly Nebula from Hubble (2022 Nov 21)

Explanation: Stars can make beautiful patterns as they age -- sometimes similar to flowers or insects. NGC 6302, the Butterfly Nebula, is a notable example. Though its gaseous wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees C, the aging central star of NGC 6302, the featured planetary nebula, has become exceptionally hot, shining brightly in visible and ultraviolet light but hidden from direct view by a dense torus of dust. This sharp close-up was recorded by the Hubble Space Telescope and is processed here to show off remarkable details of the complex planetary nebula, highlighting in particular light emitted by oxygen (shown as blue), hydrogen (green), and nitrogen (red). NGC 6302 lies about 3,500 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius). Planetary nebulas evolve from outer atmospheres of stars like our Sun, but usually fade in about 20,000 years.

Pencil Nebula ✏️

This image shows a nebula that’s part of the Vela supernova remnant – the “leftovers” of a star’s supernova explosion.

The nebula's shape suggests that it is part of the supernova shock wave that recently encountered a region of dense gas, which also caused the nebula to glow, appearing like a rippled sheet.

New images released from NASA's James Webb Space Telescope are revealing Neptune, and the planet's hard-to-detect rings, in a fresh light. https://cnn.it/3qVaWSB
