A nearby galaxy is blowing bubbles.
They’re obviously not like the soap bubbles you blew as a kid…or a bored adult washing dishes. They’re officially called nuclear superbubbles, and are formed when a black hole shoots out jets of plasma almost at light speed.
We actually have bubbles here in the Milky Way as well, although they're called Fermi bubbles. They're much older and smaller than the nuclear supers (but they're still 50,000 light years wide).
Gotta be honest here, I barely understood what I read, but it was still super interesting.
