• Using a computer model based on Voyager data, scientists have shown that the sun’s magnetic field becomes bubbly in the heliosheath due to reconnection. Credit: NASA/Goddard Space Flight Center

  • On April 8, 2010, NASA’s Solar Dynamics Observatory recorded images of gas erupting through the sun’s atmosphere that formed froth covered, curly waves that look like surfing waves. Look for them rolling around the edges of the expanding dark spots. Credit: NASA/Goddard Space Flight Center

  • If aliens discover one of the Voyager spacecraft in the emptiness of space, what could they learn about our planet Earth?

  • Swift and Hubble caught the remnants of an asteroid smash-up just weeks after the collision occurred.

  • Saturn is sending out mixed signals in recent data from NASA’s Cassini spacecraft and the NASA/ESA Hubble Space Telescope.

  • This video shows the scientists’ best guess to date of what the surface of the protoplanet Vesta might look like. It was created as part of an exercise for NASA’s Dawn mission involving mission planners at NASA’s Jet Propulsion Laboratory and science team members at the German Aerospace Center and the Planetary Science Institute.

  • This NASA retrospective looks at space shuttle Discovery on the eve of the spacecraft’s final flight.

  • NASA’s Kepler mission confirmed the discovery of its first rocky planet, named Kepler-10b. Measuring 1.4 times the size of Earth, it is the smallest planet ever discovered outside our solar system. The discovery of this so-called exoplanet is based on more than eight months of data collected by the spacecraft from May 2009 to early January 2010. This video is narrated by Kepler Deputy Science Team Lead Natalie Batalha.

  • The sun descends to the Martian horizon and sets in this 30-second movie simulation using images from the panoramic camera (Pancam) on NASA’s Mars Exploration Rover Opportunity.

  • NASA scientists have revealed the lunar soil inside shadowy craters is rich in useful materials, that the moon is chemically active, and that it also has a water cycle.
