Notes:
|
IC443 is the result of a star that expoded (Supernova) 35,000 years ago. It expelled much of it's mass, including some of the heavier elements created in it's core. The star was located in the area of a molecular cloud complex, so the explosion created a shock wave front that flouresces with excited molecular hydrogen. |
| The star that remains is a neutron star, which is extremely hot and dense. It is probably no more than 10 miles in diameter. It was located by the strong X-ray that it emits. It's movement from the center of the nebula was what helped determine the age of this interesting celestial cloud. | |
