Scientists are confused over a mysterious aurora on Saturn's north pole, because it behaves unlike any other known aurora found in the Solar system.

This was revealed by an infra-red camera carried by Cassini spacecraft. Cassini–Huygens is a joint venture by NASA, European Space Agency and ASI, currently studying the planet Saturn and its moons.

Cassini-Huygens is one of the most ambitious missions ever launched into space. Cassini was launched on October 15, 1997 and it reached Saturn's orbit on July 1, 2004.

Cassini revealed many valuable information to mankind about Saturn and its largest moon Titan. During its Saturn probe for the last four years, Cassini discovered many small moons of Saturn.

In 2006, scientists discovered a storm at the south pole of Saturn similar to hurricanes on Earth, that had never been seen on any other part of Solar system.

It's not just a ring of auroras like those seen at Jupiter or Earth. This aurora covers an enormous area across the pole.
