Getting To Know Super-Earths

Kimm Fesenmaier
Results from NASA's Kepler planet-hunting mission have indicated that the most common planets in the galaxy are super-Earths—those that are bigger than Earth but smaller than Neptune. Heather Knutson and her colleagues are using space telescopes to try to find out more about these worlds.

Textbook Theory Behind Volcanoes May Be Wrong

Marcus Woo
In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study.
