Mars Mission discovers new 'patchy' 

The Emirates Mars Mission (EMM), the Arab world's first interplanetary exploration, has made the first observations of a new type of proton aurora around Mars.

Mars missions are analogous to the aurora seen near Earth's North Pole (Northern Lights).

The Northern Lights occur on Earth as a result of the Solar Wind being drawn in by the Earth's magnetic field.

When the high-speed solar wind directly impacts Mars, a new patchy type of Martian proton aurora forms.

The aurora was discovered using snapshots of the dayside disc obtained by the Emirates Mars Ultraviolet Spectrometer.

The aurora appears as bright regions spread across the planet's dayside in two ultraviolet wavelengths associated with the Hydrogen atom.

At these wavelengths, the planet's dayside disc is uniform, and the planetary brightness is caused by Hydrogen atoms scattering sunlight.
