Astronomers may have uncovered the curious origins of the universe's most curious planets, so-called "double hot Jupiters." The team behind the research hopes their discovery will help find more of these rare planets.
Hot Jupiter extra-solar planets, or "exoplanets," are scorching hot gas giants around the size of Jupiter or above that orbit so closely to their parent stars that one of their years can last less than an Earth day. While hot Jupiters are rare, orbiting just 1% of stars, even more scarce are "double hot Jupiters." These exoplanet pairs are found in binary star systems with one planet orbiting around each of the twin stars.
