A star that may become a black hole

A rare Wolf–Rayet star, furiously shedding its outer layers. In a few hundred thousand years it may collapse into a black hole.
What you’re hearing
Webb, Chandra, and a combined infrared view from Herschel, WISE, and Spitzer. The clumpy ejected gas has a different grain from the compact X-ray core.
