Some stars streaking through the Milky Way at millions of kilometers per hour probably trace back to a supermassive black hole in a neighboring galaxy
The study looked at hypervelocity stars, ones that are screaming through space at speeds far higher than stars around them. Some of these stars are moving so rapidly that they have reached galactic escape velocity; the Milky Way’s gravity can’t hold them. In the coming eons, they’ll flee the galaxy entirely. And we have good reason to believe these runaway stars were launched by SMBHs—but how?
europa is SO uninhabitable. you couldn't make it to the potentially survivable part. and even if you could, you'd be under more pressure than our deepest oceans could ever imagine. i could go further, but i'm trying to not be a prick.
good fucking question! i don't think i replied to this post, but it's weird that it's still space-related. i wish i could remember what i actually replied to (edit - or rather which post i thought i was replying to. this was clearly a pebkac issue, but i can't figure out how it happened_
Went in thinking about Huggies, i mean Hypervelocity and went out depressed thinking about my life in europa. So the pressure i feel in germany is not only in my head?
Ohhh, hint, not hit, I'm stupid, my wants got the best of me, I thought we observed an actual head-on collision, like at impossible odds (such a collision would be possible by hypervelocity stars since they could crash into things they don't orbit, so a collision at ludicrous speeds, not just massive speeds via some converging (narrower) orbits).
Still ql to observe gravity immediately outside our galaxy, hope we get some data.
