Moon was created in giant smashup

It’s a big claim, but Washington University in St. Louis planetary scientist Frédéric Moynier says his group has discovered evidence that the Moon was born in a flaming blaze of glory when a body the size of Mars collided with the early Earth.

WUSTL-led Moon mission is finalist for NASA’s next big space venture

Nearly 40 years after the Apollo astronauts first brought samples of the Moon to Earth for study, researchers from Washington University in St. Louis are leading an effort to return to the Moon for samples that could unlock secrets of the early Solar System. Known as MoonRise, the proposed Moon mission is one of three finalists now bidding to become NASA’s next big space science venture, a $650 million mission that would launch before 2019.

Earth’s orbit creates more than a leap year

The Earth’s orbital behaviors are responsible for more than just presenting us with a leap year every four years. According to Michael E. Wysession, Ph.D., associate professor of earth and planetary sciences in Arts & Sciences, parameters such as planetary gravitational attractions, the Earth’s elliptical orbit around the sun and the degree of tilt of our planet’s axis with respect to its path around the sun, have implications for climate change and the advent of ice ages.
