Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun’s gravitational grip gradually weakens as our star ages and loses mass. Now, a team of NASA and MIT scientists has indirectly measured this mass loss and other solar parameters by looking at changes in Mercury’s orbit.

Miniature instruments and new techniques can detect and analyze microorganisms in extreme environments resembling those on Mars. Researchers demonstrate for the first time the potential of existing technology to directly detect and characterize life on Mars and other planets. The study, published in Frontiers in Microbiology, used miniaturized scientific instruments and new microbiology techniques to identify and examine microorganisms in the Canadian high Arctic – one of the closest analogs to Mars on Earth...Read More
