The effects of ancient asteroid impacts on Earth are still evident from the variety of impact craters across our planet. And from the Chelyabinsk event back in 2013, where an asteroid exploded in the air above a Russian town, we know how devastating an ďairburstĒ event can be. Now, researchers in Antarctica have discovered evidence …

Space missions often have to go where the sun don't shine. Or at least where it shines very faintly.¬† That is particularly important if the mission draws its power from the sun.¬† Luckily, engineers have a way of dealing with that problem – just make really really big solar panels.¬† That is exactly what they …
