Astronomers claim to have for the first time captured images of auroras above the giant ice planet Uranus.

Detected by means of carefully scheduled observations from the Hubble Space Telescope, the newly witnessed Uranian light show consisted of short-lived, faint, glowing dots, says an international team.

Auroras are produced in the atmosphere as charged solar wind particles accelerate in the magnetosphere and are guided by the magnetic field close to the magnetic poles.

Auroras on Uranus are fainter than they are on Earth, and the planet is more than four billion kilometres away.PTI
