Crab Pulsar

Audio is the radio signal from the pulsar in the crab nebula, a massive neutron star spinning at 1800 rpm. The movie was made by the Chandra X-Ray telescope, showing the neutron star, and rippling disturbances created by its magnetic field.
The star's magnetic field focuses radio emission into a beam that rotates like a light house beacon.

Interesting, I just slowed this down 8 times with my sound editor, and it seems to have 2 peaks instead of one. Sounds like a fast heartbeat at that speed.

[DonPMitchell]

That makes sense. There are two radio beams going out in opposite directions of the spinning star, so depending on the orientation, probably one of them is aimed more directly at us than the other.

Imagine somthing as big as a large city, yet twice as heavy as the Sun, spinning at a steady rate of 30 rotations per second, and all that Inertia came from the supernova that created it. Plus two giant radiation death-rays coming from the poles of the spinning beast that fry anything that it touches. Reminds us of how vonerable and weak we are in the Universe.

i felt weird inside after watching this any1 else feel the same?

[anuraggogetter321]

yeah sure its better but i hardly think that the 458 italia weighs over 4,000,000 times the sun being 20 km in diameter

OR have matter in the most compressed form in the universe

OR has a gravitational pull that is so much that it will suck the blood out of your entire body in 0.00000001 mili-second

OR is one of the most important discoveries of mankind BUT well the ferrari does rev upto 9000 rpm so it must be better..

dude, seriously.

(1)By the sky and the night comer -

And what can make you know what is the night comer?

It is the piercing star -

There is no soul but that it has over it a protector.

So let man observe from what he was created.

He was created from a fluid, ejected,

Emerging from between the backbone and the ribs.

Indeed, Allah , to return him [to life], is Able.(9)

Is that it's real sound? Pretty much real. U know, they're super fast.

[DonPMitchell]

Smaller would be faster, and it depends on the angular momentum of the original star. Also, pulsars slow down, so older ones are slower. They slow down because they lose angular momentum via gravity waves, radiation, and interactions with the acretion disk of matter around them.

[DantehMan]

My goodness, 1800rpm...it doesn't even seem possible. I love space so much.

[DonPMitchell]

Hehe. Typical pulsars spin a few times a second. But some, like B1937+21, spin at 642 revolutions per second, so they sound like a musical tone. Google for "Sounds of Pulsars" and you can find a page with a number of audio samples.

[DonPMitchell]

This is also why spaceships traveling throught "wormholes" is a bad idea. Yeah, you might go in a wormhole and come out somewhere far away in space, but as a burst of gamma rays and protons and stuff.

[BatchDrake]

if we take the intense gravitation pull in the surrounding area in consideration we can talk about a dramatical death where you are literally smashed into the surface and your body explodes (implodes) into a deadly burst of gamma rays.
