Gravitational microlensing study – Say “Hello?”

An article titled “One or more bound planets per Milky Way star from microlensing observations” was published January 11, 2012 in Nature1 . Previously, planets have been detected using radial velocity methods but only those planets in orbits closer to their star could be detected. Microlensing allows detection of planets at greater distances. Their conclusion … More Gravitational microlensing study – Say “Hello?”
