NASA Releases Images of a Mid-level Solar Flare
The NASA Solar Dynamics Observatory (Little SDO) captured this dazzling solar flare in action last week. The solar flare is the bright flash of light on the right limb of the sun. A burst of solar material erupting out into space can be seen just below it.
Saturn by Cassini's wide-angle camera. The image was captured in infrared light on April 4, 2014. The northern polar hexagon shows up so clearly here! The image processing was made by one of our PL friends, Maksim Kakitsev. Thanks for sharing, Maksim. This is beautiful work! Credit: NASA/JPL-Caltech/Space Science Institute/ @Maksim Kakitsev
APOD: 2006 October 16 - In the Shadow of Saturn
The robotic Cassini spacecraft now orbiting Saturn recently drifted in the giant planet's shadow for about 12 hours and looked back toward the eclipsed Sun. Saturn's rings light up so much that new rings were discovered: Saturn's E ring, the ring created by the newly discovered ice-fountains of the moon Enceladus, and the outermost ring visible above. Far in the distance, visible on the image left just above the bright main rings, is the almost ignorable pale blue dot of Earth.
A Hitchhiker's Guide to Space & Plasma Physics
Neptune is the 8th planet from the Sun and the smallest of the gas giants. Neptune was the first planet found by mathematical prediction after unexpected change in Uranus' orbit were observed. Neptune is named after the Roman god of the sea. The blue coloring is the result of methane in the atmosphere. The winds are nine times faster than those on Earth and believed the strongest in the solar system. | Image: Steve Albers, NOAA/GSD
Saturn’s Weird Moon, Pan | WordlessTech
Saturn's Weird Moon, Pan.. Strange flying-saucer-shaped moons embedded in Saturn’s rings have baffled scientists studying images transmitted by the ESA’s Cassini Spacecraft. New research suggests that the oddly shaped moons, Pan and Atlas, are born largely from clumps of icy particles in the rings themselves, a discovery that could shed light on how Earth and other planets formerd from the disk of matter that once surrounded our newborn sun.
