Weighing potentially habitable planets around Sun-like stars remains surprisingly difficult: a methods test found that precise measurements often require planets weighing about 8 to 10 Earth masses. The latest reports also explore brilliant radio bursts from a rapidly spinning brown dwarf, a possible hotspot on another brown dwarf, and how transit changes can expose a planet that never crosses its star.
