And as promised, here is the crab nebula in infrared, taken with the Spitzer space telescope.

Notice the swirl of gas and the bright thing in the center. That is the remains of the exploded star and it is now something known as a pulsar. A pulsar is a star that has a beam of radiation shooting out of the magnetic pole. As the star rotates, that beam is periodically directed towards the earth and the star brightens. Think of it like a light house. We can measure these pulses quite accurately and pulsars are some of the most accurate clocks in the universe. Some pulsars have been found to have pulses accurate to 10^-10 seconds. That's pretty amazing that such a huge object (larger than Earth) can rotate with such precision.

HOLY FUCKING SHIT THE WORLD IS ENDING !!!!!!!!!

POST THIS IN EVERY THREAD, EVERY BOARD. HURRY THE FUCK UP.

A FUCKING PULSAR JUST BLEW UP AND THE RADIATION IS COMING.

HOLY FUCK

I HOPE YOU FUCKS REPENTED AND ASKED FOR GODS FORGIVENESS OF YOUR SINS. TIME FOR DEATH IS NEAR!

Just interested in what your favorite sci-fi space quote is.

So if we had eyes that could detect x rays for example, would they be a completely new color?

Would it be possible to have a writing utensil that wrote in xrays or some other invisible light?

Astronomers observed a supernova in 1979.

If the star collapsed and formed into a Neutron star, we would be seeing a decline in X-ray emissions as it cooled down.

If the star collapsed and formed into a black hole, we would see a steady production of X-rays produced by the accretion disk around the black hole as it draws in matter from either a binary companion or the supernova remnant.

Our observations are showing that the X-rays emitted by SN 1979C are at a constant level. So it is likely that the star collapsed into a black hole.
