The young crescent Moon’s nightly motion from 31 December 2016 to 3 January 2017 carries it past dazzling planet Venus and first-magnitude Mars. A small telescope also reveals outermost planet Neptune, which passes just 0.02 degrees from Mars around 7h UT on 1 January, offering observers around the world a New Year’s Day treat.
The Mars Camera, CaSSIS (Colour and Stereo Surface Imaging System), on ESA’s ExoMars Trace Gas Orbiter captured its first high-resolution images of the Red Planet last week. Developed by a team at the University of Bern in Switzerland, CaSSIS is providing spectacular views, including the Hebes Chasma region at a resolution of 2.8 metres per pixel.
Find a location that offers you an unobstructed view of the horizon from south to southwest an hour after sunset. With clear skies, you’ll be able to follow Venus and Mars from night to night on their celestial peregrinations through the constellations of Sagittarius and Capricornus. The two planets almost keep pace with each other throughout the remainder of November.
Researchers using NASA’s Mars Reconnaissance Orbiter have determined that frozen beneath a region of cracked and pitted plains on the Red Planet there lies about as much water as fills Lake Superior, largest of the Great Lakes. Scientists examined part of Mars’ Utopia Planitia region with the orbiter’s ground-penetrating instrument, revealing a deposit more extensive in area than the state of New Mexico.
