Stereo Tracks Solar Storms From Sun To Earth (3:01) NASA's STEREO spacecraft and new data processing techniques have succeeded in tracking space weather events from their origin in the sun's corona to impact with the Earth, resolving a 40-year mystery about the structure of the structures that cause space weather: how the structures that impact the Earth relate to the corresponding structures in the solar
A Guide to Solar Flares (3:02) Solar flares are classified according to their strength. The smallest ones are B-class, followed by C, M and X, the largest. A powerful X-class flare can create long lasting radiation storms, which can harm satellites, communications systems, and even ground-based technologies and power grids.
Curiosity Rover Trailer (1:38) This animation shows key events of NASA's Mars Science Laboratory mission Curiosity rover, which launched in late 2011 and landed on Mars in August 2012.
Vesta Full Rotation Movie (0:59) In this movie, strung together from a series of images provided by the framing camera on NASA's Dawn spacecraft, we see a full rotation of Vesta, which occurs over the course of roughly five hours. These images were obtained in 2011, from a distance of about 3,200 miles (5,200 kilometers).
DNA Building Blocks Can Be Made in Space (2:49) NASA-funded researchers have evidence that some building blocks of DNA, the molecule that carries the genetic instructions for life, found in meteorites were likely created in space. The research gives support to the theory that a "kit" of ready-made parts created in space and delivered to Earth by meteorite and comet impacts assisted the origin of life.
