Webdesk: US astronomers’ new telescopic data may reveal the dynamics of Uranus’s atmosphere, which spins on its side.
Uranus is a mysterious planet that NASA’s probe only saw once over four decades ago. The third-largest planet in our solar system has secrets.
A New Mexico telescope found a quarter-sized polar cyclone near Earth’s north pole.
Scientists published in Geophysical Research Letters.
Moreover, This allowed experts to glimpse deeper into the icy giant’s atmosphere, like Neptune’s.
“While, The general makeup of its atmosphere and interior is similar to Neptune—as far as we know—Uranus has some pretty unique features,” said planetary scientist Alex Akins of NASA’s Jet Propulsion Laboratory in California, lead author of the study.
“It spins sideways. Its magnetic field remains mismatched with its rotational axis. “The atmospheric circulation and internal heat release appear weaker than Neptune, but there is still a range of dynamical features and storms,” Akins said.
Methane gas in its atmosphere makes the third-largest planet in our solar system blue-green. Hydrogen and helium dominate its atmosphere.
About 31,500 miles (50,700 km) wide. Uranus could fit 63 Earths.
Uranus’ orbit around the sun is 1.8 billion miles (2.9 billion km), approximately 20 times Earth’s. It orbits 84 years.
Uranus appears to roll around the sun due to its tilt.
The Very Large Array telescope revealed warmer, drier air at the north pole, indicating a significant cyclone.
They estimated the storm’s centre but not the cyclone’s diameter, which may be broader than Earth.
Polar cyclones are found on all planets except Mercury and Saturn’s moon Titan.
Moreover, Akins noted, “Polar cyclones are regions of high winds moving in a direction determined by the planet’s rotation—clockwise on Venus, Uranus and anti-clockwise for the rest—with differing air properties between the inside and out.”
“The way they form is different from planet to planet,” Akins said.
Moreover, Seasonal sunlight modulates their strength on Earth. Uranus’s formation is unknown. Moreover, It’s longer-lived than other cyclones and presumably forms from a different balance of atmospheric processes, making it a more characteristic [enduring] aspect of the atmosphere. Hurricanes form, travel, and dissipate quickly.
Uranus is mostly ice—water, methane, and ammonia.
While, It has 27 tiny moons and two feeble rings. Uranus has the coldest atmosphere of the eight planets, including outermost Neptune.
“There are lots of unknowns,” Akins remarked.
How did it tilt? Is its interior ‘icier’ than Jupiter and Saturn’s? Why don’t atmospheric banding features match wind speeds? Why is the pole drier? Ocean worlds?
