Astronomers discover a blue aurora on Mars.
An international team of scientists has been able to show for the first time in history that the Northern Lights, a luminescent phenomenon is observed in the night sky from Earth, it can also be seen on other planets.
The polar aurora can also be observed on Mars, but instead of the green and red stripes of the Northern Lights on Earth, on Mars This phenomenon is electric blue, the researchers explain.
The scientists obtained the results of the study through a laboratory experiment, called ‘Planeterrella’ which allowed simulate the aurora in atmospheric conditions on Mars .
The researchers showed that the upper atmosphere of Mars glows blue depending on solar activity. Moreover, this atmosphere can be closer to Earth than previously thought.
“An astronaut to look up while walking down the red Martian soil could, after intense solar flares, observe the aurora sight, “says the scientist Cyril Simon Wedlund, one of the main authors of the study.
The discovery of scientists is not only fascinating, but could also help researchers understand how he got away eventually the Martian atmosphere
