Space mystery as scientists baffled by bizarre temperature changes recorded on Neptune

Led from the University of Leicester, the team found unseasonal cooling followed by “dramatic” warming at the south pole. As it orbits around the Sun, Neptune experiences seasons, much like on Earth. Unlike our seasons, however, those on Neptune each lasts more than 40 Earth years, as the planet takes nearly 165 years to complete an orbit around the Sun. At present, it is summertime in the southern hemisphere on Neptune — as it has been since 2005 — with the solstice having just passed. In a new study, astrophysicist Dr Michael Roman of the University of Leicester and colleagues set out to see how much, in the wake of the solstice, temperatures across the planet’s southern hemisphere were changing.
