Mars might Also Have Aurora Displays Visible to Naked Eye

A team of international scientists for the first time in the history have been able to predict the occurrence of Auroras that are visible to naked eye on a planet other than earth.

Researchers captured auroras on Mars which suggested that the Red Planet has an atmosphere that is very much similar to that of earth.

Team of researchers from the Aalto University in Finland found that Mars changed its color to blue depending on the activity of the Sun.

In order to show aurora, scientists used numerical simulations and laboratory experiment called the Planeterrella, used to stimulate the aurora.

Cyril Simon Wedlund, researcher at the department of radio science and engineering, Aalto University, Finland, said, "Study indicates strongest color in Martian aurorae is deep blue.

Green and red also occur, like on Earth. Astronaut looking up while walking on the red Martian soil would be able, after intense solar eruptions, to see phenomena with naked eye".

Furthermore, while explaining the aurora, Wedlund said that they occur when electrically charged particles enter a planetary atmosphere and excite its atoms and molecules in the presence of local magnetic field lines.

Experts said that it is not the first time that aurora has been seen on the Red Planet. Earlier in 2005 European Space Agency's (ESA) Mars Express satellite first showed depicted aurora on the Mars.

Aurorae on earth are generally red or green in color, and this is due to the presence of atomic oxygen, however, one can sometimes also witness blue-purple due to ionized molecular oxygen.

Skywatchers in the far north and far south can see the colorful aurora light displays on Earth, but Mars-exploring astronauts will probably need to be in the planet's southern hemisphere to see the best aurora show, said scientists.
