IC444. The Jellyfish Nebula |
Supernova
remnant in Gemini |
The Jellyfish nebula (IC443) in Gemini is a
supernova remnant that is supposed to happen 8000 years ago (3.000 -
30.000). Although it shares some characteristics with other supernova
remnants like the Crab nebula, in this case, the gas threads do hot
show a regular outward expansion. What can be observed is a compression
effect towards the east and expansion efect towards the west, due to
the shock waves colliding with a molocular front. The nebular area on
the left of the image is IC444. The more prominent stars are Mu and Eta
Geminorum. Distance to Earth: 5.000 light years. |
