Crab Nebula Heart
The Crab Nebula seems to have most of what’s in the celestial bestiary. It is one of the most spectacular nebulas in the sky. It’s a supernova remnant. It has a pulsar that emits in radio, visible, ultraviolet, and X-ray wavelengths. It even has a well-established pedigree since it was sighted by royal Chinese astronomers when light from the supernova arrived here in 1054.
“The Crab Nebula and the star at the center of it are the Rosetta Stone of modern astrophysics,” said Dr. Martin Weisskopf, Project Scientist for the Chandra X-ray Observatory.
