OBJECT DESCRIPTION AND IMAGE SESSION

 

The picture shows part of this large Vela Supernova Remnant region. The filaments structures is the result of a massive star that exploded some 11.000 to 12.000 years ago. The outer layers of the stars are still expanding to the interstellar space forming the gas structures with high energy particles which is still visible today. This remnant is the one closest to us and it is embedded in a larger and older supernova remnant known as the Gum Nebula. 

 

The object presents a huge relative size that gives the possibility to explore some other interesting areas.  Pismis 4 is an open cluster on the top of the central arc; and vdB-Ha 34 stands in the center of the central arc with an apparent size of 13.8 arc minutes.
