ALMA finds compelling evidence for pair of infant planets around young star



Charlottesville VA (SPX) Dec 13, 2016
Astronomers now know that our galaxy is teeming with planets, from rocky worlds roughly the size of Earth to gas giants bigger than Jupiter. Nearly every one of these exoplanets has been discovered in orbit around a mature star with a fully evolved planetary system. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) contain compelling evidence that two newborn planets, each about the size of Saturn, are in orbit around a young star known as HD 163296. These planets, whic ... read more

A major challenge in the exploration of Mars by robots is its uneven surface, which is marked by trenches and craters.

There, scientists from the Robotics Innovation Center of the German Research Center for Artifi ... more

Lunar sonic booms
The sonic boom created by an airplane comes from the craft's large, speeding body crashing into molecules in the air. But if you shrank the plane to the size of a molecule, would it still generate a shock wave? Scientists such as University of Iowa physicist Jasper Halekas hope to answer that question by studying miniature shock waves on the moon. These sonic boomlets, physicists believe, ... more
