SuperBlueBloodMoon: New Ideas About Lunar Formation

January 31 will be an early morning show for Moon lovers. Starting about 2.51 a.m. Pacific Time will be a lunar eclipse, or “blood moon” as the Moon passes through Earth’s shadow and picks up a reddish tint. At the same time, the full Moon of Jan. 31 is also a “supermoon” when the Moon is relatively close to Earth and looks bigger and brighter, and a “blue Moon” because it is the second full Moon in one month.

NASA is calling it a “SuperBlueBloodMoon.” (If it’s cloudy where you are, NASA is also running a live stream of the eclipse.)

Podcast: Synestia, a New Type of Planetary Object

In this month’s Three-Minute Egghead, Sarah Stewart and Simon Lock talk about synestias. A synestia is a new type of planetary object, they proposed, formed when a giant collision between planet-size objects creates a mass of hot, vaporized rock spinning with high angular momentum. Synestias could be an important stage in planet formation, and we might be able to find them in other solar systems.
