June 15, 2015 To the human eye, Mercury may resemble a dull, grey orb but this enhanced-colour image from NASA’s Messengerprobe, tells a completely different story. Swathes of iridescent blue, sandy-coloured plains and delicate strands of greyish white, create an ethereal and colourful view of our Solar System’s innermost planet. These contrasting colours have been chosen to emphasise the differences in the composition of the landscape across the planet. The darker regions…
Saturn: Bright Tethys and Ancient Rings (Sept 16 2012) Image Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA Explanation: How old are Saturn's rings? No one is quite sure. One possibility is that the rings formed relatively recently in our Solar System's history, perhaps only about 100 million years ago when a moon-sized object broke up near Saturn. Evidence for a young ring age includes a basic stability analysis for rings, and the fact that the rings are so bright (...) #Saturn #space
On February 17, 1998, Voyager 1 became the farthest man-made object from Earth, passing Pioneer 10 at 69 AU from the sun. From this day onwards to the present, Voyager 1 has been the farthest man made object from Earth.
Ring of Fire. A medida que el sol se elevó sobre Australia en la mañana del viernes, 10 de mayo, el disco solar se convirtió en un anillo de fuego. Eclipse anular de sol al sur de Newman, Australia. 06h: 33m: 48s, hora local. En un eclipse anular, la Luna no es lo bastante grande como para cubrir todo el disco solar y un anillo deslumbrante de fuego sobresale alrededor de la Luna perfilando del sol su delicada corona.

Long ago, in the largest canyon system in our solar system, vibrations from "marsquakes" shook soft sediments that had accumulated in Martian lakes. The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on new NASA images.
