SCIENCE: The oldest Pictish fort

This week on science the oldest Pictish fort has been found in Scotland. The Picts were around in the late iron age and early medieval period, and have left behind Pictish Stones as some of the earliest and best-preserved markers of their existence. The oldest of those stones we have found date back to the 6th century, but this new site is even older and could shed new light on life in eastern Scotland during that time. Then, two new exoplanets have been discovered in the habitable zone surrounding a red dwarf only 12 light years away. Not only could these planets support water, but they also could possibly be breeding grounds for extraterrestrial life in the universe.
