As we head into winter, many people will see these frosty figures show up on their windows, or on the hoods of their cars. And though you’re seeing them here on earth, such patterns are excellent examples of how ice forms in outer space.
It's going to be harder to find habitable Earth-like worlds than we thought. An analysis of three hot Jupiters yielded only 1/10 to 1/1000 the amount of water predicted by models. This means our planetary formation theories are incomplete — and that we should expect to see lower water abundances on potentially…
For the first time ever, scientists have found actual chemical evidence of water on a rocky object outside of our solar system. The water wasn’t found on a planet, but rather the remains of one shredded to bits by its dying parent star.
