Astronomers have found more real-life versions of Luke Skywalker's home planet Tatooine from "Star Wars" — alien worlds that see two suns rise and set each day instead of one. And these two newfound worlds are also extremely close to the habitable zones of their parent stars, scientists say.
The discovery cements what appears to be a new class of twin sun alien planets and may help astronomers estimate how many of such binary stars possess planets. The finding also suggests that many planets might lie in the habitable zones of such systems, researchers said.
