Most familiar stars peacefully orbit the center of the Milky Way. But citizen scientists working on NASA’s Backyard Worlds: Planet 9 project have helped discover an object moving so fast that it will escape the Milky Way’s gravity and shoot into intergalactic space. This hypervelocity object is the first such object found with the mass similar to or […]

1 million miles an hour is so fast, the speed of light is still 671 times faster.

[-] afk_strats@lemmy.world 29 points 11 months ago

So you're saying it's relatively slow?

[-] Klear@sh.itjust.works 6 points 11 months ago

Yes. Still relatively fast though too.

It is pretty wild how so much mass could be accelerated to that speed.

The idea that a 3 body system could cause it is really cool. Probably not useful to us, but still very cool

I'm getting mass just thinking about it.

Did Fukitech release a 3 body system!?

Dammit, I just got the 2!

[-] wise_pancake@lemmy.ca 27 points 11 months ago

That’s 0.0015c

The galaxy presumably.

I'm guessing the milkyway's core seeing as they are taking about it possibly having enough velocity to escape the galaxy

OHLOOKITSTHEREawww it's gone

[-] WhatYouNeed@lemmy.world 2 points 11 months ago

Whatta ya mean, you blinked??

[-] possiblylinux127@lemmy.zip 11 points 11 months ago* (last edited 11 months ago)

That's sort of fast I suppose

[-] DeanFogg@lemm.ee 4 points 11 months ago

What is it and where it goin'?

[-] abysmalpoptart@lemmy.world 5 points 11 months ago* (last edited 11 months ago)

Isn't the sun revolving around the center of the milky way at approximately 450,000 mph? And the Earth revolves around the sun, so we're moving about half as fast as this new object right now. One million is pretty fast, but context makes it a little less shocking.

[-] Klear@sh.itjust.works 4 points 11 months ago* (last edited 11 months ago)

That's not context, that's using arbitrary reference frames.

[-] abysmalpoptart@lemmy.world 3 points 11 months ago

I don't think that's entirely fair to say. The headline reads sensationally about a celestial object, but our own sun is traveling at almost half that speed, and we're following it. I'm not trying to prove that the Earth is incredibly fast, only that the headline may sound more impressive than it is.

[-] iAvicenna@lemmy.world 4 points 11 months ago

clearly an Interstellar traveller

[-] papertowels@lemmy.one 3 points 11 months ago

Ah, a photoid strike, finally.

[-] DragonTypeWyvern@midwest.social 1 points 11 months ago

The question is, did they miss their first target?
