    Young Features Hint at Hidden Depths
    Lava flows have spread across the floor of this large collapsed area. Their lack of impact craters and steep sides show that they erupted relatively recently. Discoveries such as these are causing scientists to rethink their ideas about the Moon's internal composition. Perhaps a large reservoir of radioactive elements is generating heat deep within the Moon and keeping it volcanically active.
