  • Baby star blasts jets of water into space

    Astronomers have found a nascent star 750 light years from earth that shoots colossal jets of water -- a cosmic fire hose -- out its poles in bullet-like pulses. In a process that almost defies adjectives and analogies, each jet of water is the equivalent of a hundred million times the water flowing through the Amazon River every second and the speed of the jet is the equivalent of 80 times the mu

    極付近から猛烈な勢いの水を吹き出している星を、750光年先で発見。噴き出す水の量は、アマゾン川の流量の100万倍で、速さはライフル銃の発射速度の80倍。この星は発生の初期で、どの恒星もこの段階を踏むと
  • NASA Radar Finds Ice Deposits at Moon's North Pole - NASA Science

    Using data from a NASA radar that flew aboard India's Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon's north pole. NASA's Mini-SAR instrument, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 1 to 9 miles (2 to15 km) in diameter. Although the total amount of ice depends on its thickness in each c
