#PencilNebula | This shock wave plows through space at over 500,000 kilometers per hour. Moving toward to bottom of this beautifully detailed color composite, the thin, braided filaments are actually long ripples in a sheet of glowing gas seen almost edge on. About 5 light-years long and a mere 800 light-years away, the Pencil Nebula is only a small part of the #VelaSupernovaRemnant.

The Weird and Beautiful World of Fluid Dynamics

Supersonic Shock Wave When an object moves faster than the speed of sound, funny things start to happen. The bullet in the image above is moving so fast, the air in front of it can’t get out of the way quickly enough. So it starts to pile up in front of the bullet, forming an area of compressed air — a shock wave. The same thing happens with supersonic jets. As they fly faster than the speed of sound, they build up a shock wave in front of them. The sonic boom that accompanies these…

Cosmic Cocoon

Using observations from NASA's Chandra X-ray Observatory, researchers have obtained the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas surrounding the star that exploded. This discovery may help astronomers understand why some supernovas are much more powerful than others
