IT degree programmes fully booked

114 young people have chosen Aarhus University's three new degree programmes as their first priority.

Simulation of wind erosion on Mars. The quartz ampoule contains particles of olivine basalt and a Mars-like atmosphere. By shaking the ampoule, the researchers simulate wind-generated saltation, ie. that the wind causes the sand grains to make short jumps over the surface. The friction of the particles creates electrical charges, and the yellow star illustrates that an argon atom has lost an electron. The small electrical charges cause the particles to glow slightly, as illustrated in the four pictures to the right. Graphics: Mars Simulation Laboratory, AU

Methane vanishing on Mars: Aarhus researchers propose new mechanism as an explanation.

The processes behind the release and consumption of methane on Mars have been discussed since methane was measured for the first time for approx. 15 years ago. Now, an interdisciplinary research group from Aarhus University has proposed a previously overlooked physical-chemical process that can explain methane's consumption.
