The particle — which probably came from a distant galaxy — was spotted by the Cubic Kilometre Neutrino Telescope (KM3NeT), a collection of light-detecting glass spheres on the floor of the ...
Here on Earth, we tend to take showers for granted. But for astronauts stationed in space, taking a quick rinse—much like cooking, eating, using the toilet, and just about every other mundane, ...
