The almost-perfect alignment of Earth's line of sight with the orbital plane of the double pulsar PSR J0737-3039A/B gives rise to an eclipse of pulsar A once per orbit as it moves behind pulsar B (Credit: McGill University/Daniel Cantin/DarwinDimensions)

Is there an audio component to this vid?

If not then

SIGH

NewScientist really need to work on improving their youtube vids. They're on really interesting topics and i love all this stuf, but the 1 - 2 min quick-clip vids they post with that irritating narrator of theirs are so shallow and uninformative it annoys the hell outa me.

Youtube provides them a great opportunity to present some really interesting science to a wider audience in a creative way, they really should invest in it!

Death by black hole,what a good way to die. It would feel good ,than bad,youd be stretched,then go trippy, then white out. HOWEVER,If you were to survive (somehow) youd probly wind up 10000000, light years into another demension. Fucking sweet

@Isanion i completely agree - well said. Pretty amateur effort for the likes of new scientist.

@SwordShockwave well said :)

Very Educational stuff

I missed the part where it proved Einstein. Probably needs a bit more audio... Maybe this was the thrust:

"J0737-3039 might be the only system that can test spin precession with eclipses. In order to do the measurements, one star's beam one needs to be shining at the Earth. The other needs to pass in front of the star in our line of sight."

It's not about to die, it's the magnetically affected core left when a blue supergiant goes supernova, providing it didn't already turn into a black hole.

a pulsar is a star that that is going to die (i think), and it starts to spin in a really fast speed and it gets around 16 km in diameter but a tee spoone of the mass in the pulsar can weight over like 1 million tons or so... <3<3<3<3<3<3 space <3<3<3<3<3<3 so exalted ;P DONT POST ME IF I AM WRONG! (saw this in a 2 hour long cocumentary in discovery channel) PWNS!!!
