Reporting and analysis tagged exoplanets.
Laboratory experiments suggest that intense magnetic fields can trap plasma streams, potentially explaining why coronal mass ejections are rarely observed on active stars.
The detection of escaping helium on a distant rocky world provides new evidence that terrestrial planets can maintain stable atmospheres in habitable zones.
Astronomers have identified a third giant planet orbiting the young star Beta Pictoris by isolating its unique atmospheric chemical signature from dense surrounding debris.
