Using images captured by the European Space Agency’s Mars Express spacecraft, researchers have created a cloud atlas of Mars, to better understand the climate of the Red Planet

The Arrhenius equation, which has accurately described rates of chemical reactions for more than a century, may have to be tweaked for the quantum realm
