It is a world wrapped in mystery - the seventh planet from the sun, Uranus, seen up close just once nearly four decades ago by a passing NASA probe and still warily guarding its secrets.
But new observations from a telescope located in New Mexico are providing a fuller understanding of its atmosphere, including the detection of a polar cyclone whose centre measures a quarter of Earth's diameter, swirling near its north pole.
Scientists were able to gaze more deeply into the atmosphere of Uranus - a planet classified as an ice giant, like its planetary neighbor Neptune - than ever before. The findings painted a picture of a planet more dynamic than previously known.
