Hubble Reveals Fresh Insights into Uranus’ Atmosphere

Rapid Summary

• Hubble’s 20-year study of Uranus observed seasonal and atmospheric changes on the ice giant with data spanning from 2002 too 2022.
• Uranus, about four times Earth’s diameter, has an atmosphere primarily composed of hydrogen, helium, and traces of methane giving it a blue tint. It rotates on its side with a tilted, off-centered magnetic field.
• Observations were conducted by astronomers from the University of Arizona and University of Wisconsin using Hubble’s Space Telescope Imaging Spectrograph (STIS).
• Researchers found methane is unevenly distributed across Uranus’ atmosphere, being strongly depleted near the poles-a pattern consistent over two decades.
• Aerosol haze structures considerably brightened in the northern polar region as Uranus approaches its northern summer solstice in 2030; meanwhile optical observations revealed solar radiation impacts aerosol dynamics.
• Findings indicate complex atmospheric circulation patterns including polar downwelling and upwelling regions elsewhere.
