Exoplanets—planets that orbit stars beyond our solar system—have transformed our understanding of the universe. Since the first confirmed discovery in the 1990s, more than 5,000 have been ...

Anthony L. Piro (Carnegie Observatories)(Submitted on 3 May 2018) In our solar system, the presence of rings is exclusive to the gas giants, but is this the case for all […] ...

Crystal clouds on a distant world may shimmer like sun dogs, hinting at exotic optics shaped by heat, wind, and starlight.
