Using radial velocity measurements, an international team of astronomers has identified a second planet orbiting a nearby M-dwarf star known as Gliese 536. The newfound alien world turns out to be at least a few times more ...
Large exoplanets are more easily detected than small ones. It's axiomatic. While large planets block out more starlight during transits, small planets block out much less, letting them hide in the overpowering glare from ...
