Planets spinning on their sides were long thought to have climates too extreme for life as it is known on Earth, but now scientists find that these "rotisserie" worlds might be more hospitable.
25 February 2015, 07:00 AM ET
Although these "golden stars" were spotted during a search for an extraterrestrial galactic Internet, the researchers say intelligent aliens have nothing to do with their flickering patterns, as far as they can tell.

One day I imagine that humanity will be able to visit other planets in the Solar System, and venture even further to other stars, but this has always seemed very far away. That’s the reason why I applied for the Mars One mission.

The photo, which was released today (Feb. 24), is a composite of dozens of images taken in late January by Curiosity's Mars Hand Lens Imager. The mosaic provides a great view of the "Pahrump Hills" outcrop at the base of the huge Mount Sharp.
