Sun pummeled Earth’s wimpy magnetic field
U. ROCHESTER (US)—The Earth’s magnetic field 3.5 billion years ago was only half as strong as it is today, new research shows. The weakness—coupled with a strong solar wind—likely allowed particles from the young Sun to strip water from early Earth’s atmosphere. (more…)

Playing hide and seek with exoplanets
U. COLORADO (US)—A precise “laser ruler” is being developed to look for Earth-like planets around other stars. The device will measure tiny changes in infrared light caused by the gravitational wobble of small, cool stars as they are tugged back and forth by their rocky planets. (more…)
