The Vice President of the United Arab Emirates has just announced an unprecedented discovery, brought to light by the Arab interplanetary mission: that of a "discrete" aurora, which would appear in the atmosphere of the dark side of Mars.
The Hope probe, the main tool of the UAE‘s interplanetary mission around Mars -the first in the Arab world- has recently made an exceptional discovery. Equipped with an ultraviolet spectrometer, the probe managed to capture a phenomenon as spectacular as it was unexpected: a bluish aurora, almost mauve at times, which oscillates in the atmosphere of the red planet, on its hidden side.

In addition to the visual aspect -the discreet aurora of Mars is at least as magnificent as the aurora borealis and polar lights of the Earth- of this discovery, it is especially its scientific impact that is important here, especially in the appreciation that we have of the interactions between the sun’s rays and the different planets of the solar system.
These mysterious magnetic fields on the surface of Mars not only resemble those of the Earth, but other similarities are to be underlined, such as the fact that the planet would not have a global magnetic field generated by its core. Undoubtedly, the red planet has not finished delivering all its secrets…
