So, if my old brain did the math right, it'll get here in about 2.5 billion years?

Technically the two galactic clouds are already touching, according to some paper I read a couple years ago

I thought something felt funny.

Oh, wow. I expected someone to correct me and say it will be much sooner due to the size of the two galaxies but didn't think I was that far off.

Extremely technical use of "technically" - we're talking about maybe 1 atom of hydrogen per cubic meter, but if that atom is bound by a galaxy's gravity it sort of is part of that galaxy, kinda.

So it's coming at us at 0,1% the speed of light?

We're gonna need a crew of oil rig workers to divert it.

A bonus restretch and crop to just the galaxy. You can see the arms!

what did you use to capture/process this?

This was on a canon 90d on a star adventurer 2i, with a 50mm f1.8 lens stopped to around f5.6

30sec exposures at iso 800 stacked up using Siril
