New Evidence: Auroras on Exo-Planets

New Evidence Indicates Auroras Occur Outside Our Solar System

Jan. 21, 2013 — University of Leicester planetary scientists have found new evidence suggesting auroras – similar to Earth’s Aurora Borealis - occur on bodies outside our solar system.

Auroras occur on several planets within our solar system, and the brightest - on Jupiter – are 100 times brighter than those on Earth. However, no auroras have yet been observed beyond Neptune.

A new study led by University of Leicester lecturer Dr Jonathan Nichols has shown that processes strikingly similar to those which power Jupiter’s auroras could be responsible for radio emissions detected from a number of objects outside our solar system.
