[WH40k] Do we have any idea what's going on outside our galaxy?

To our knowledge, has anyone been to another galaxy and returned? Do we know if the other galaxies in the universe are all as fucked as ours? Is it even possible to make it to another galaxy via the warp, and if so would the light of the Astronomicon be visible?

We know the Tyranids are attacking from mutliple different directions into the galaxy, so presumably they've eaten or at least occupied much of the surrounding galactic cluster.

Maybe some Eldar and Ork colonies out in the fringes but who knows.
