Why NASA Is Making Air Explode Using Electricity - The Electric Arc Shock Tunnel
The Electric Arc Shock Tunnel (EAST) at NASA Ames can generate hypervelocity shockwaves in test atmospheres to understand what happens during atmospheric entry. This system uses a capacitor bank that stored up to 1.25MegaJoules to drive a shockwave in a test gas then observe the light emitted. This is essential to determining the radiative ...

Supernova Explosion
613K views · 9.2K reactions | An incredible cosmic blast! 勞 Astronomers believe this explosion, SN 2015F, was triggered by the collision of a white dwarf and a Sun-like star in the NGC 2442 galaxy. While the actual supernova lit up 80 million years ago, its light has only recently reached Earth, allowing us to witness this ancient event.  Credit: Changsu Choi & Myungshin Im (Seoul National University) | The Galactic Void | Facebook
