Large Underground Xenon (LUX) Dark Matter Experiment Our experiment is a 350 kg liquid xenon time-projection chamber that aims to directly detect galactic dark matter in an underground laboratory 1 mile under the earth, in the Black Hills of South Dakota, USA.
Oct 2010 Saturn: Light, Dark, & Strange Credit: Cassini Imaging Team, ISS, JPL, ESA, NASA That large orb on the left must be Saturn itself. Those arcs on the right are surely the rings. The dark band running diagonally must be the shadow of Saturn on the rings. That leaves the unusual dark bands superposed on Saturn's disk -- are they the shadows of the rings? ... So the rings themselves cause the dark streaks on Saturn. These rings segments appear dark because they are in the shadow of…
The Super-Kamiokande detector in Japan, an underground tank that holds 50 million liters of water, captures neutrinos that emanate from a particle accelerator nearly 300 kilometers away. When a neutrino hits the detector, it can produce charged particles, whose high speed through the water emits a flash of light, triggering phototubes mounted in the walls of the Super-K tank. The experiment investigates muon neutrinos transforming into electron neutrinos.
Largest water reservoir discovered in black hole. The reservoir holds as much as 140 trillion oceans, or more than 4,000 times more than exists in the entire Milky Way. It exists as vapour spread across hundreds of light years. While water has been found across much of the universe previously, this is interesting because of the fact this reservoir is 12 billion light years away, meaning that this water existed when the universe was only 1.6 billion years old.
