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, ...

This image shows blue spheres representing relative amounts of Earth's water in comparison ... Oceans account for only a "thin film" of water on the surface. Some fast facts: About 3,100 mi ...

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 ...

Some phenomena on Earth are so baffling that even scientists ... size of the colossal white crystals emerging from every surface of the horseshoe-shaped chamber. While preparing new land for ...
