Using the radial velocity (RV) method, an international team of astronomers has discovered two new exoplanets transiting a nearby M-dwarf star known as GJ 1002. The newfound alien worlds have masses similar to that of our ...
The nearest known exoplanet to Earth, the planet orbiting Proxima Centauri, experiences some pretty nasty space weather from its parent star. But previous work on the space weather of Proxima relied on a lot of assumptions. ...
