The explosion is over, but the consequences continue. About twelve thousand years ago, a relatively normal star in the constellation Vela suddenly exploded, creating a strange point of light briefly visible to humans living near the beginning of recorded history. The outer layers of the star crashed into the interstellar medium, driving a shock wave that is still visible today. The featured image, taken piecemeal over 60 hours from the Khomas Region of Namibia, captures some of that filamentary and gigantic shock in visible light, with details highlighted by hydrogen (red) and oxygen (blue) emissions. As gas flies away from the detonated star, it decays and reacts with the interstellar medium, producing light in many different colors and energy bands. Remaining at the center of the Vela Supernova Remnant is a pulsar, a star as dense as nuclear matter that spins around more than ten times in a single second.

How is a pulsar or "the center" of that identified?

I'm seeing the head of a luminescent rooster, looking to the right, with its comb being blown by cosmic winds, also to the right. Yes, I think I'd bet 10,000 quatloos on that.

Incredible pic, in any case.

Cosmic silky rooster.

Hah!

You got me curious, so I searched around a little bit, and it seems that the pulsar is very faint, and flashes on a timed cycle. Looks you need some pretty heavy-duty equipment to record it, either a radio telescope or high-grade optical telescope, plus a way to log long exposures.

Basically, it seems pretty elusive for other than the best amateurs with special equipment. Something like that, anyway.
