About 80 light years from Earth is a lonely planet. Its name is "PSO J318.5-22" and it was discovered by an international team of astronomers during a wide field survey. The little guy is about six times the size of Jupiter, with all the properties of a gas giant, and probably formed just a short 12 million years ago, making it a relatively young planet.
Thanks to the extreme sensitivity of the Pan-STARRS 1 (PS1) wide-field telescope on Haleakala, Maui, the unique heat signature of the newborn planet stood out against a massive field of data. This prompted astronomers to do follow-up observations - observations which show that PSO J318.5-22 is all by itself, drifting in space - with no host star or orbit to speak of.
