Sir Isaac Newton would be amazed by this awesome video, showing Saturn moons causing waves as they orbit near its F Ring. These images can only be taken every 15 years, during Saturn's equinox. Thankfully, Cassini is there now. In the video you can see Prometheus (in the inner side) and Pandora (on the outer side), disturbi (Read More)

The beautiful infographic "50 Years of Space Exploration" [nationalgeographic.com] shows exactly the content denoted in its title. A delimited line on the bottom shows the relative distances in interstellar space, and the current positions of our most distant spacecrafts, such as the Voyager 1 and Pioneer 10. However, the m (Read More)
