Kepler scientists find freaky solar system that’s unlike anything we’ve seen before
NASA scientists working on the Kepler Mission have discovered an unprecedented solar system, in which two planets with vastly different densities and compositions are locked in a surprisingly close orbit around their star. The finding shows that there is much greater diversity in the composition of solar systems than we’d previously thought.
Prior to our discovery of exoplanets, our solar system offered a standard blueprint for astronomers speculating about what other solar systems might look like — namely, rocky planets on the inside, and large gas giants farther out. Then, with the discovery of enormous inner-system gas giants, our conceptions of what other systems might look like took a drastic turn. And now, with the discovery of these two new exoplanets, our imaginations are proving to be completely inadequate. Read more here
