Our closest red supergiant, Betelgeuse will become a violent and bright supernova soon(ish)
For context, our closest red supergiant star is Betelgeuse. It is currently on the cusp of exploding, as it transforms into a supernova. The star is already spewing gases from its surface as it prepares to ascend into supernova — superheating nearby celestial gas and dust into a spectacular light-show.
As the star prepares to self-destruct, there’s a nearby wall cloud formation of dust. According to the ESA, it’s technically the edge of a nearby interstellar cloud, being illuminated by Betelgeuse. The two are posed to collide:
If the bar is a completely separate object, then taking into account the motion of Betelgeuse and its arcs and the separation between them and the bar, the outermost arc will collide with the bar in just 5,000 years, with the red supergiant star itself hitting the bar roughly 12,500 years later.
