Astronomy Picture of the Day - M1: The Crab Nebula

Explanation: The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers in the year 1054. This sharp, ground-based telescopic view combines broadband color data with narrowband data that tracks emission from ionized sulfur, hydrogen, and oxygen atoms to explore the tangled filaments within the still expanding cloud. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is visible as a bright spot near the nebula's center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is a mere 6,500 light-years away in the constellation Taurus.

I visited M1 a couple months ago. Here's the postcard I got.

A cataclysmic explosion of a star leaving spinning neutron star, just 6500 light years away.

Ping to bagster, haven’t I heard you use the term Crab Nebula before? Had something to do with a troll’s mom...

1,800 RPM and 1.4 times heavier than the sun. There’s a bit of power there.

It’s spinning like a top, like a giant searchlight, sending out beams of electromagnetic radiation, enough radiation to burn the skin off your bones several light years away.

Yep, and when two of them collide, it fries everything within several thousand light years.

Yet balanced enough that it does not explode from the force.

I always find nebula rather nebulous.

This was what happened when Samantha Carter and Rodney McKay did an experiment that went sideways.
