Found: Planets Skimming a Star’s Surface

Brian Jackson

A new planet-hunting survey has revealed planetary candidates with orbital periods as short as four hours and so close to their host stars that they are nearly skimming the stellar surface. If confirmed, these candidates would be among the closest planets to their stars discovered so far. DTM Post Doctoral Fellow, Brian Jackson, presented his team’s findings, which are based on data from NASA’s Kepler mission, at the American Astronomical Society’s Division of Planetary Sciences meeting Tuesday.

How old is the moon? About 100 Million Years Younger Than We Once Thought

How old is the moon?

New research and recent analyses of lunar rocks suggests an object 5 times the mass of Mars actually collided with Earth and created a monster impact that led to the formation of Earth’s moon between 4.4 billion and 4.45 billion years ago. This new timeline marks the moon 100 million years younger than we once thought and reshapes scientists’ understanding of the early Earth and moon.

MESSENGER Postdoctoral Fellow, Paul Byrne, entered a video into the international competition, FameLab, on the global contraction of Mercury. He advanced to the second round where he submitted a video about how large volcanoes on Mars can sink into the ground and came in first place. He will compete with winners from the other heats at National Geographic Headquarters in April 2014 in the U.S. FameLab final. The winner of that final will represent the U.S. in the international finals in London in July 2014.
