This is called a “Wolf-Rayet” star, WR 124.
Thanks to NASA’s “Astronomy Picture Of The Day” website for this and many other fantastic space images.
Part of their description of this star is:
“Some stars explode in slow motion. Rare, massive Wolf-Rayet stars are so tumultuous and hot that they slowly disintegrating right before our telescopes. Glowing gas globs each typically over 30 times more massive than the Earth are being expelled by violent stellar winds.”
Violent, perhaps. But also amazingly beautiful!
