How did the Butterfly Nebula get its Wings? It’s complicated

A color rendition of NGC 6302, the Butterfly Nebula, created from black-and-white exposures taken by the Hubble Space Telescope in 2019 and 2020. In the violet-colored regions, strong stellar winds are actively reshaping the nebular wings over the past 900 years. The other features range in age from 1200 to 2300 years.Bruce Balick/University of Washington/Joel Kastner/Paula Baez Moraga/Rochester Institute of Technology/Space Telescope Science Institute

Something is amiss in the Butterfly Nebula. When astronomers compared two exposures of this planetary nebula that had been taken by the Hubble Space Telescope in 2009 and 2020, they saw dramatic changes in the material within its ‘wings...

Hubble provides Holistic View of Stars gone Haywire

1) The “wings” of NGC 6302 are regions of gas heated to more than 36,000 degrees Fahrenheit that are tearing across space at more than 600,000 miles an hour. NGC 6302 lies between 2,500 and 3,800 light-years away in the constellation Scorpius.
2) Recently, NGC 7027’s central star was identified in a new wavelength of light — near-ultraviolet — for the first time by using Hubble’s unique capabilities

As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas...
