Astonomers discover pulsar star racing across the Milky Way

Astronomers discovered a pulsar, a kind of zombie star, racing across the galaxy so quickly that it could get from Earth to the Moon in six minutes flat. The dead star has a tail pointing back toward the remnant of a supernova that exploded 10,000 years ago. Astronomers suspected this might have provided the kick that sent the pulsar speeding off, but had to wait for 10 years of telescope data to make their case convincing.

Luckily, PSR J0002 isn’t coming toward us, and is instead speeding mostly across our line of sight. This is good news, because even the leftover core of a massive star still weighs more than our sun, and would wreak gravitational havoc as it passed by any other object. “If it were really between the Moon and Earth, that would be the end of it,” says Frank Schinzel, lead author on the research. “If it were more than a few light-years away, we might see a nice show from neighboring solar systems’ disruption.” The pulsar is going so quickly it will eventually leave the Milky Way entirely.

Waste. Of. Time.

Thx for fricking my night up.

May be a planet the size of 1000 of our galaxies racing torwards us that is 10 times faster than that one.
Our telescopes may not be capable of seeing it just yet.

If you saw a hundred million objects, and one of them was moving 50 times faster than all the rest, I think you'd say it was "racing".

That's about 2.4 million miles per hour.

Giggity.

Booooooo! This is pretty much true about anything in space. Stop it. Stop it.
Quit turning science into a 15 second Entertainment Tonight segment.

quote:It won't reach that speed for a few years, and it will only be that fast because it will essentially be falling toward the sun. Just a couple years ago a comet crashed into the sun faster than this probe. I'm not impressed.
Humans have launched a probe moving 430,000 miles per hour (18% of that racing star) so I'm not impressed.
Also, the pulsar is somewhere in the neighborhood of 1,000,000,000,000,000,000,000,000,000 times more massive than our probe, give or take half a dozen orders of magnitude. Things that size just don't move that fast. The energy involved is mind-boggling. And you're more impressed by us launching a little probe and letting gravity take over?
