From WASHINGTON UNIVERSITY IN ST. LOUIS Chemistry says Moon is proto-Earth’s mantle, relocated Data confirm model in which impact pulverizes Earth like a sledgehammer hitting a watermelon Measurements of an element in Earth and Moon rocks have just disproved the leading hypotheses for the origin of the Moon. Tiny differences in the segregation of the…

From RICE UNIVERSITY: Earth’s carbon points to planetary smashup Element ratios suggest Earth collided with Mercury-like planet HOUSTON — (Sept. 5, 2016) — Research by Rice University Earth scientists suggests that virtually all of Earth’s life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic planet similar…
Early in the morning of Sept. 1, 2016, NASA’s Solar Dynamics Observatory, or SDO, caught both Earth and the moon crossing in front of the sun. SDO keeps a constant eye on the sun, but during SDO’s semiannual eclipse seasons, Earth briefly blocks SDO’s line of sight each day – a consequence of SDO’s geosynchronous…
From Nature (h/t to Dr. Leif Svalgaard) Astronomers have discovered evidence of a small, rocky planet orbiting our nearest star – and it may even be a bit like Earth. Nobody knows whether the planet, called Proxima b, could ever sustain life. The little planet orbits our sun’s nearest neighboring star, Proxima Centauri, making it the closest…
NASA’s Kepler confirms 100+ exoplanets during its K2 mission The largest haul of confirmed planets obtained since the space observatory transitioned to a different mode of observing includes a planetary system comprising four promising planets that could be rocky UNIVERSITY OF ARIZONA An international team of astronomers led by the University of Arizona has discovered…
From NASA Goddard: NASA Camera Shows Moon Crossing Face of Earth for 2nd Time in a Year For only the second time in a year, a NASA camera aboard the Deep Space Climate Observatory (DSCOVR) satellite captured a view of the moon as it moved in front of the sunlit side of Earth. “For the…
