Crash! Boom! A new infrared image of Betelgeuse suggests the star and its winds will smash into the interstellar medium in only a few thousand years.

If the bar [of gas] 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 [star’s] outermost arc will collide with the bar in just 5000 years, with the red supergiant star itself hitting the bar roughly 12 500 years later.
