Distant Planetary System is Just as 'Neat' as Ours

  Researchers measure the orientation of a multiplanet system and find it very similar to our own Solar System. In this artist interpretation, the planet Kepler-30c is transiting one of the large starspots that frequently appear on the surface of its host star. The authors used these spot-crossing events to show that the orbits of [continue reading]
