#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.


Galactic Pyrotechnics on Display | A galaxy about 23 million light-years away is the site of impressive, ongoing, fireworks. Rather than paper, powder, and fire, this galactic light show involves a giant black hole, shock waves, and vast reservoirs of gas.


The red arc in this infrared image from NASA's Spitzer Space Telescope is a giant shock wave, created by a speeding star known as Kappa Cassiopeiae. Image credit: NASA/JPL-Caltech


The infrared vision of NASA's Spitzer Space Telescope shows how a massive speeding star is electrifying its surroundings


After a massive star in the Milky Way exploded, it produced a shock wave of high-energy particles, seen here in purple. In the background, you can see stars as imaged by the Digital Sky Survey. Chandra captured data on the shock wave in 2003. It is estimated to be 2,400 light-years away.


If I had a top 8 on this yould be on it. Mind blowing. 'Pillars of Creation' - This nebula no longer exists. In 2007, astronomers announced that they were destroyed about 6,000 years ago by the shock wave from a supernova. Because of the limited speed of light, the shock wave's approach to the pillars can currently be seen from Earth, but their actual destruction will not be visible for another millennium.

Space Tornado

SPACE TORNADO Gas and dust swirl rapidly before collapsing inward to form a new star. Jets of material from the new star generate shock waves through the surrounding gases and dust, forming this "tornado" nebula.

Supersonic Shock Waves of a T-38C Aircraft

This schlieren image of a T-38C was captured using the patent-pending BOSCO technique. This schlieren image of T-38C shock waves was captured using the sun’s edge as a light source and then processed using NASA-developed code.


Elbaite is a member of the tourmaline family. The pink variety of elbaite is called rubellite. The tourmaline family encompasses eleven minerals all with a ring arrangement of silicon, boron, and oxygen. All tourmalines have the special property called piezoelectricity. This means that they can acquire an electric charge when struck by an object, or subjected to high pressure, such as the shock wave from an explosion.
