Fermi Satellite Clocks Pulsar Going 2.5 Million Miles Per Hour (upi.com)
schwit1 quotes UPI:
Astronomers have discovered a pulsar traveling at unprecedented speeds. Observations by NASA's Fermi Gamma-ray Space Telescope suggest the star is moving through space at 2.5 million miles per hour.... "Thanks to its narrow dart-like tail and a fortuitous viewing angle, we can trace this pulsar straight back to its birthplace," Frank Schinzel, a scientist at the National Radio Astronomy Observatory in New Mexico, told NASA. "Further study of this object will help us better understand how these explosions are able to 'kick' neutron stars to such high speed...."
Scientists named the high-speed pulsing star PSR J0002+6216, or J0002 for short. The star is located in the Cassiopeia constellation, 6,500 light-years from Earth... Analysis of the pulsar's trajectory and pulsing tail suggest the spinning neutron star was ejected by a supernova named CTB 1. Scientists estimated J0002 was expelled from CTB 1 approximately 10,000 years ago.
Scientists aren't totally sure how J0002 accelerated to such tremendous speeds. In the wake of the supernova explosion from which the pulsar originated, expelled gas and dust from the exploded companion star likely outraced J0002. Eventually, the shell of stellar shrapnel was slowed by interactions with interstellar gas, but astronomers theorize that some of stellar debris may have coalesced into a region of dense matter, forming a "gravitational tugboat" that is pulling J0002 through space.
J0002 was discovered by "citizen scientists" scanning data from NASA's Fermi satellite, according to the article.
"Participants in the Einstein@Home project have identified 13 gamma ray pulsars."

For those who have long abandoned the imperial units that's around 4 million kilometers per hour, or 3.7% of the speed of light.
Its speed is relative to what?
:wq
2 trains pass each other, moving opposite directions at 50mph each.
To observers on either train, the other is going 100mph. OMG! Why is their train faster than mine?!
Do you know why I pulled you over?
Have gnu, will travel.
1.1E6 m/s .0037c
Or
Why not translate it into the units I understand? What is that in Celsius??*

What kind of backwords shithole country still measures shit in unscientific miles??
That's no pulsar...

I appreciate this is an embarrassingly basic question but what does that actually mean? Is it that everything else is basically 'still' relative to us? Or is it more that this object has a natural 'home' of surrounding objects that you'd expect it to stay with but in fact is moving away from?
Good old metric system where everyone fucks up the decimal places with it.
It looks like there is a mistake "is moving through space at 2.5 million miles per hour". Due to how the speed of light works, they'd be seeing how fast it was going, not how fast it is going.

How is the Riemann zeta function like Trump rallies? Both have an endless number of trivial zeros.
I know a guy who can get that speeding ticket thrown out.
it would be one heck of an expensive speeding ticket!
Sorry, the times where the USA were leading anything but destruction and illness are loong gone.
"Your" researchers are all foreigners. Back then Germans that came over, now south-/east-Asians, wandering off to Germany and Canada.
And "your" products are made in China and south-east Asia too.
Just like your tits and Eiffel towers and food and elections and personalities and media, they're the epitome of fake.
In fact, if you want to describe the USA in one word, it would be "fake".
English is what you get, if you take German, add centuries of extreme alcoholism (helloo gin!), and then try to save it with largr doses of the snobbery languages du jour: French and Latin.
Call us when you got your ambiguities fixed (try compound words) and your spelling rules follow one system instead of having two and not giving a fuck about either.
I don't even expect being able to express nuances a subtle as in German.

Where did you mom jokes come from?
I don't think I ever heard one 10 years ago
Now they're everywhere.
I'm sure Scotty can get some more outta her.
uBlock has a list for blocking those ad blocker detectors. Try enabling that and clearing your cookies.
Someone should arrest these speeding pulsars in case they crash into something!

I'm a bit disappointed. I was hoping it moves at relativistic speeds. Unfortunately 0.37% of c isn't even getting close.
Opened this article looking for some insightful comments about what this means, how this will impact our understanding of space and the universe and what do I get? A bunch of jokes about the use of the term 'miles'. [sigh]

Pulsar going like a Bat Out Hell, she's gone, gone, gone!
This is not a pulsar, it's Voltron on its way to save another planet.
Jokes aside: At this distance how do we know this isn't some massive spaceship traveling at nearly the speed of light?
All those moments will be lost in time, like tears in rain... time... to... die...
