Pluto wags its tail... its plasma tail, that is. We discovered a region of cold, dense ionized gas tens of thousands of miles beyond Pluto -- the planet’s atmosphere being stripped away by the solar wind and lost to space. Our New Horizons spacecraft observed a cavity in the solar wind -- the outflow of electrically charged particles from the sun. This cavity is populated with nitrogen ions forming a “plasma tail” of undetermined structure and length extending behind the planet. Details: http://go.nasa.gov/1Lrhihp #PlutoFlyby

It is a common misconception that the Sun is yellow, or orange or even red. However, the Sun is essentially all colors mixed together, which appear to our eyes as white. When we see the Sun at sunrise or sunset, it may appear yellow, orange, or red. But that is only because its short light rays (blue, purple) are scattered out by the Earth's atmosphere, much like small waves are dispersed by big rocks along the shore.

The Falcon hypersonic HTV-2 is an unmanned, rocket-launched, maneuverable aircraft that glides through the Earth’s atmosphere at incredibly fast speeds.

The U.S. military lost contact with an unmanned hypersonic glider shortly after it launched on a test flight today (Aug. 11) as part of a global strike weapons program to develop vehicles capable of flying at Mach 20 and reach any target in the world in an hour.
