Snow in TW Hydrae

ALMA radio telescope noticed snow in TW Hydrae system

Thanks to an ALMA radio telescope of scientists found snow in very young planetary system. According to scientists, for the first time in the remote young planetary system was recorded snow. Using a Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope, astronomers photographed a precipitation in the form of snow in system of the TW Hydrae. It is a star in constellation of Hydra being in 176 light years from us. This is the orange dwarf of a class K of the main sequence like T Tauruses. By the sizes and weight it is slightly less than our Sun. The TW Hydrae is included into star association with the name of the same name into which also enters and 2M1207 – the red dwarf with recently opened planet. The proto planetary disk is found in a star. The age of a star makes about 10 million years. Astronomers explain that small parts of water quickly freeze in planetary

TW system of the Hydrae, turning into snowflakes. Earlier in a proto planetary disk of this star was revealed a large amount of water which periodically passes to a firm condition in the form of ice and snowflakes. Among molecules which are in the atmosphere of TW Hydrae and also can freeze and turn into snowflakes: carbon (CO2) oxide, methane (CH4) and carbon (CO) monoxide.
