WORLDS COLLIDE: Earth may have collided with Mercury sized planet in the past – carbon tells the tale

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…


Rare Moon and Earth eclipse of the Sun seen from the SDO

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…

Image montage showing the Maunakea Observatories, Kepler Space Telescope, and night sky with K2 Fields and discovered planetary systems (dots) overlaid. An international team of scientists discovered more than 100 planets based on images from Kepler operating in the 'K2 Mission'. The team confirmed and characterized the planets using a suite of telescopes worldwide, including four on Maunakea (the twin telescopes of Keck Observatory, the Gemini­North Telescope, and the Infrared Telescope Facility). The planet image on the right is an artist's impression of a representative planet.
