Xenon plasma, gas mixture consisting of electrons, ions and atoms, is of real interest for space propulsion. By ejecting gas at a speed ten times higher than a conventional chemical thruster, plasma thrusters require ten times less fuel. Nevertheless, although plasma thrusters are already operation…

Their dimensions and distances make most astrophysical phenomena inaccessible to experimentation. To better understand them, researchers use laboratory astrophysics, that is to say, they reproduce on a small scale the conditions in which different phenomena are formed or evolve. This month, the pre…
