Astronomers have captured the first visible-light photograph of an extrasolar planet. The planet is about the size of Jupiter, and scientists believe that the system in which it resides could harbor more worlds.
Imagine a solar system where a life-bearing planet is slowly pulled in closer to its star. If life could survive the ensuing climate change, it would provide a clear example of the Gaia hypothesis in action.
New research shows that a distant exploding star could have triggered the formation of our solar system. The study is helping astrobiologists understand the conditions in which habitable planets might form.
Astronomers have discovered that two terrestrial planets orbiting a distant star have recently suffered a violent collision. The new observation is unlike anything seen before, and sheds light on how interactions between planets can affect habitability.
New simulations show that stars like the sun can migrate great distances over time. The study may challenge the idea that galaxies have 'habitable zones' that are more suited for life than other areas.
