Stephenson 2-18

You're just flying through the edge of a random star cluster when out of nowhere your whole cockpit glows bright crimson. Heat alarms immediately start going off all over your screens. You run a quick scan to see what's going on and realize you just ran into Stephenson 2-18—literally one of the largest red hypergiant stars ever found. The thing is so absurdly huge it makes whole solar systems look tiny. Your ship gets caught in its heavy gravity pull, and a deep energy pulse echoes right through your hull.
