Cosmic Journeys
Alien Planets & Eyeball Earths: The Search for Habitable Planets. Find out where to look for Extraterrestrial Life. What planets are likely to have the right conditions? And what makes Earth special?
So far, in this age of planet hunting, we've yet to find anything like our solar system... with rocky inner planets in neat circular orbits, and evenly spaced gas giants on the periphery.
Instead, astronomers have glimpsed a diverse planetary zoo, with giant planets in wide orbits around their parent stars, others that swing in so close they leave a comet-like tail, or molten rocky worlds emblazoned with
oceans of lava. These finds have added new complexity to theories of how solar systems emerge in the birth of a star.
