MOON — A cavernous lava tube was this week confirmed to exist beneath the surface of the moon. <br /><br />The discovery was after by a team of Japanese and American scientists using data from the SELENE and GRAIL spacecraft to acoustically map the enormous lava tube.<br /><br />These tubes are volcanic underground passages formed by flowing lava to funnel the substance. Once the flow stops, the tube remains with features similar to a cave.<br /><br />The chasm is around 100 meters wide and 50 kilometers long, reported the Guardian. It is located in the Marius Hills region of the celestial body.<br /><br />The cave could provide shelter to astronauts during moon missions, protecting them from dangerous cosmic radiation. This could potentially allow for the development of a lunar exploration base.<br /><br />Details of the finding was published in the journal, Geophysical Research Letters.
