Astronomers have discovered a "rogue planet," up to seven times the size of Jupiter, floating through space without a parent star.
The object, described as "the most exciting free-floating planet candidate," is approximately 100 light years away and between 50 to 120 million years old.
The planet has been labelled CFBDSIR2149 and is thought to be part of a nearby stream of young stars known as the AB Doradus Moving Group.
It was identified by researchers using the European Souther Observatory's Very Large Telescope and the Canada-France-Hawaii Telescope.
Its comparative proximity, and the absence of a bright star very close to it, has allowed the team to study its atmosphere in great detail.
