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.

Image: Tiny wobbles of a bright star HD 73344 have revealed the mass of a nearby sub-Neptune exoplanet
Additionally, another signal hints at the presence of a previously undetected planet orbiting farther from the star. HD 73344 is an F-type star approximately 115 light-years away. At roughly 20% larger than our Sun, it hosts a sub-Neptune exoplanet with a density similar to Saturns. The possible second planet has been detected with a minimum mass around one-third that of Jupiter...
