Discoveries: snow on Mars, on Jupiter storm

Winter on Mars came into its own. The Rovers send pictures of the first snow of carbon dioxide. Photo of this unusual and rare phenomenon on the red planet obtained by the apparatus MRO, published NASA.

Presents snow “drifts” bluish hue was taken by the HiRISE camera at the end of March. Snow on Mars is different from earth. Since the main atmospheric gas, the red planet is carbon dioxide (where it is about 95%) when it freezes at temperatures below -120 C, it turns into hardened ice particles and falls to the surface. The largest number it accumulates at the poles. As explained “MK” the space research Institute, Russian HEND, who is already 15 -th year “watching” the seasonal processes on Mars aboard the American apparatus “Mars Odyssey”, records covers dry snow on the polar caps of the planet. Experts specify that on closer examination the usual snowflakes on Mars can’t be seen, the snow particles there have a size in 1/10 of a millimeter. All together they look more like dust settling on the surface of the planet.

Meanwhile, astronomers from the European southern Observatory introduced the VHR data from images of the gas giant Jupiter in the thermal and optical ranges. They were made with the help of the Chilean telescope VLT(Very Large Telescope). Of the nearly hundreds of pictures, the participants received a single dynamic image of the planet on which it was possible to observe the movement of the club of gas in the atmosphere. Recall that on 4 July this year, the orbit of Jupiter, will arrive NASA’s “Juno”, whose main objective will be to clarify the question of the presence of Jupiter’s solid core and explore the most popular on the planet, phenomena – storms.
