Newborn exoplanet might be the youngest ever observed

NASA's planet-hunting Kepler space telescope has made another interesting cosmic discovery, the space agency reports this week. The youngest, fully formed exoplanet ever observed has been spotted just 500 light-years from Earth in the K2–33 star system. The star is a mere 5 million to 10 million years old, meaning the planet, lovingly dubbed K2–33b, is about the same age and practically a baby on the cosmic scale.
