WW31.jpg1998-WW3186 visiteThis is an artist's view of a Kuiper Belt binary object, called 1998 WW31. These icy bodies orbit each other at the fringe of our Solar System.
The illustration depicts one member of the duo in the foreground; its companion - the dark, round object - is in the background. The objects are about the same size. Both are illuminated from behind by the Sun [the white dot at upper left]. Like other Kuiper Belt objects, this duo orbits the Sun, completing a circuit every 301 years while Pluto orbits the Sun every 248 years.

West Spur-HD-S2-PIA06917.jpgSunset on West Spur271 visiteQuesta immagine è una "invenzione" di Lunar Explorer Italia: i colori del Cielo e della superficie del Pianeta Rosso sono stati riveduti e corretti usando la logica e le immagini (ed informazioni ad esse relative) disponibili.
Il Sole che tramonta e gli effetti prismatici sono un banalissimo effetto speciale (Microsoft Photo Editor) che abbiamo utilizzato per rendere più affascinante questa (comunque) "fredda" visione di Marte.

mars-dust-devil-large-bg.jpgMartian Dust Devil122 visiteAh, Martian Summer! Finally, the days are long, just like on dear old Earth. And daytime highs rocket all the way up to a balmy 20°C (68°F) from the Summer nighttime low of -90°C (-130°F), meaning you and your fellow astronauts can warm up your machinery earlier to get a good start on mining operations.
But those warm daytime temperatures also bring alive the Martian devils. Dust devils, that is.
You were caught in one just yesterday - and a devilishly terrifying experience it was! This was no little Arizona desert whirlwind, only a few tens of meters high and a few meters across and past you in seconds.
No, what hit you yesterday was a monster column towering kilometers high and hundreds of meters wide, 10 times larger than any tornado on Earth. Red-brown sand and dust whipping around faster than 30 meters per second (70 miles per hour) dropped visibility to zero, scouring your faceplate, driving dust into every fold and wrinkle of your spacesuit.
For 15 minutes you huddled and endured the buffeting. The scariest part was the incessant crackling and flashing of miniature lightning bolts nipping at you and your rover, and the loud static on your radio that prevented you from calling for help.
Could this really happen?

s going to Titan-IMG000616-br500.jpgDown to Titan!81 visiteCaption NASA originale:"This artist's conception of the Cassini orbiter shows the Huygens probe separating to enter Titan's atmosphere. After separation, the probe drifts for about 3 weeks until reaching its destination, Titan. Equipped with a variety of scientific sensors, the Huygens probe will spend 2-2,5 hours (maybe more) descending through Titan's dense, murky atmosphere of nitrogen and carbon-based molecules, beaming its findings to the distant Cassini orbiter overhead. The probe could continue to relay information for up to 30 minutes after it lands on Titan's frigid surface, after which the orbiter passes beneath the horizon as seen from the probe".
