News that a NASA scientist has announced fresh progress on Proxima b has pushed our nearest known exoplanet neighbor back into the spotlight, sharpening long-running questions about whether this rocky ...

The nearest known exoplanet to Earth, a 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 ...
