Geologists discover mysterious subduction zone beneath Pacific, reshaping understanding of Earth"s interior
University of Maryland scientists uncovered evidence of an ancient seafloor that sank deep into Earth during the age of dinosaurs, challenging existing theories about Earth's interior structure. Located in the East Pacific Rise (a tectonic plate boun.....»»
Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb
Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimp.....»»

Study suggests moon may have been captured from space rather than formed from collision particles
Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basalti.....»»
