Exoplanets form never-seen-before celestial alignment

CelestialScience writes: The heavens have aligned in a way never seen before, with two exoplanets overlapping as they cross their star. Teruyuki Hirano of the University of Tokyo, Japan, and colleagues used data from the Kepler space telescope to probe KOI-94, a star seemingly orbited by four planets. It seems that one planet candidate, KOI-94.03, passed in front of the star and then the innermost candidate, KOI-94.01, passed between the two. The phenomenon is so new it doesn't yet have a name though suggestions include "planet-planet eclipse", "double transit", "syzygy" and "exosyzygy".
