Tidal Heating Shrinks the Goldilocks Zone

A previously little-considered heating effect could shrink estimates of the habitable zone of the Milky Way’s most numerous class of stars — ‘M’ or red dwarfs — by up to one half, says Rory Barnes, an astrobiologist at the University of Washington in Seattle. That factor — gravitational heating via tides — suggests a menagerie of previously undreamt-of planets, on which tidal heating is a major source of internal heat. Barnes presented the work yesterday at a meeting of the American Astronomical Society’s Division on Dynamical Astronomy in Timberline Lodge, Oregon.

Vesta Was Almost a Planet

Vesta, the second largest object in the main asteroid belt, has an iron core, a varied surface, layers of rock and possibly a magnetic field — all signs of a planet in the making, not an asteroid.

So concludes an international team of scientists treated to a virtual front row seat at Vesta for the past 10 months, courtesy of NASA’s Dawn robotic probe.

Oldest Mayan calendar found goes way beyond Dec. 12, 2012

The hieroglyphs, painted in black and red, along with a colorful mural of a king and his mysterious attendants, seem to have been a sort of handy reference chart for court scribes in A.D. 800 — the astronomers and mathematicians of their day. Contrary to popular myth, this calendar isn’t a countdown to the end of the world in December 2012, the study researchers said.

“The Mayan calendar is going to keep going for billions, trillions, octillions of years into the future,” said archaeologist David Stuart of the University of Texas, who worked to decipher the glyphs. “Numbers we can’t even wrap our heads around.”
