Polar Cyclone Discovered on Uranus by Scientists

Scientists have detected a polar cyclone on Uranus, whose center measures a quarter of Earth's diameter. Uranus is an ice giant planet that spins on its side and has a misaligned magnetic field with its rotational axis. The planet's atmosphere is colder than any other planet in our solar system, and it is surrounded by two sets of rings and 27 small moons. The researchers used a telescope in New Mexico to observe the planet's atmosphere and found moving air at the north pole that was warmer and drier, evidence of a strong cyclone. Uranus has only been visited by a spacecraft once, Voyager 2, in 1986.

"Polar Cyclone Discovered on Uranus by NASA"

NASA scientists have detected a polar cyclone on Uranus, which is the first of its kind to be spotted on the planet. The cyclone's center measures a quarter of Earth's diameter and is swirling near the planet's north pole. The researchers used the Very Large Array telescope in New Mexico to see below the clouds at the top of the atmosphere, finding circulating air at the north pole that was warmer and drier, evidence of a strong cyclone. Uranus is the third-largest planet in our solar system and is classified as an ice giant.

First-ever Polar Cyclone Observed on Uranus by NASA Scientists

NASA scientists have detected a polar cyclone on Uranus for the first time, using ground-based telescopes to examine radio waves emitted from the ice giant. The observations went deeper into Uranus' atmosphere than any before, revealing that the circulating air at the north pole seems to be warmer and drier, the hallmarks of a strong cyclone. The findings confirm that all planets with substantial atmospheres in our solar system show signs of a swirling vortex at the poles.

First Polar Cyclone Spotted on Uranus by NASA Scientists

NASA scientists have detected a polar cyclone on Uranus for the first time by examining radio waves emitted from the planet's north pole. The observations, collected in 2015, 2021, and 2022, went deeper into Uranus' atmosphere than any before, revealing that the circulating air at the north pole is warmer and drier, the hallmarks of a strong cyclone. The findings confirm that all planets with substantial atmospheres in our solar system show signs of a swirling vortex at the poles.
