Unlike Earth, the Moon has no active volcanoes. This is surprising as liquid magma is believed to exist deep inside the Moon. Scientists have now found that this hot, molten rock could actually be so dense that it is too heavy to rise to the surface. For this experiment, microscopic reproductions of moon rock were put at the extremely high pressures and temperatures found inside the Moon and their densities measured with powerful X-rays.
Scientists have found a layer of liquefied molten rock in Earth's mantle that may be acting as a lubricant for the sliding motions of the planet's massive tectonic plates. The discovery may carry far-reaching implications, from solv... Read Post
NASA's Cassini spacecraft has found possible ice volcanoes on Saturn's moon Titan that are similar in shape to those on Earth that spew molten rock. Topography and surface composition data have enabled scientists to make the best ca... Read Post
Contrary to Earth, our Moon has no active volcanoes, and the traces of its past volcanic activity date from billions of years ago. This is surprising, because recent Moonquake data suggest that there is plenty of liquid magma deep w... Read Post
