Welcome everyone to yet another exciting week of science news. Today we’ll talk about why Mars glows green, an amazingly cool way to make magnets hover, a study which found that a supposed piece of alien tech isn’t alien tech, surprising absolutely no one, plans to use the entire moon as a gravitational wave detector, progress with D-wave’s quantum computer, why Saturn’s rings will temporarily become invisible, wires that learn, energy from indoor lights, and of course, the telephone will ring.
