#Ukrainian military intelligence (#HUR) #drones on Aug. 11 struck the #OrenburgHeliumPlant, a key #Russian facility lying some 1,200 kilometers from the front line in #Ukraine, a source in the agency told the Kyiv Independent.

"This is the only facility in #Russia that produces [#helium], a critically important component used in #rocket manufacturing, the #SpaceIndustry, and the #aviation sector," the source claimed.

Yellowstone holds potentially untapped cache of 'carbon-free' helium for rockets, reactors and superconductors
Conventional helium production comes with enormous carbon emissions, so scientists are looking for alternatives in places like Yellowstone, Tanzania's Rukwa Rift and India's Bakreswar-Tantloi province.

It turns out that Yellowstone and the Bakreswar-Tantloi province also sit on ancient, helium-producing rocks. Yellowstone is rooted in the Wyoming Craton, which contains 3.5 billion-year-old rocks, and faults on the edges of the caldera likely form conduits for huge amounts of helium, according to the new study.

Three weeks ago, the scientific journal Nature @nature reported the discovery of the most energetic #neutrino ever observed. Its energy is 16,000 times greater than the strongest particle collisions created by the Large Hadron Collider and corresponds to 30 times the energy needed to press a computer key.

The neutrino was discovered in an underwater observatory in the Mediterranean, one of three neutrino detectors in water - two in the Mediterranean and one at Lake Baikal. At the geographic South Pole, there is the #IceCube neutrino detector under the ice. Other detectors exist underground in China, Italy, and Japan.

All these #detectors are not located on the Earth's surface because the Earth itself acts like a #telescope for neutrinos. Neutrinos are extremely light, electrically neutral particles that interact very weakly with matter and pass through the Earth. When they collide with atomic nuclei, charged particles are produced that move faster than light in water or ice, emitting blue light that is captured.

Water and ice are ideal media for detecting neutrinos because they provide large volumes to detect these particles while shielding against cosmic radiation and other disturbances. IceCube even utilizes 1 cubic kilometer of ice.

Neutrinos are the second most abundant particles in the universe, after photons, but are difficult to study because they interact so little with matter. Interestingly, dark matter and dark energy, which make up 95% of the universe, also interact very weakly with normal matter, while the remaining 5% consists of elements like #hydrogen and #helium, of which only 0.5% is visible matter (such as #stars).

Vor drei Wochen berichtete die Fachzeitschrift Nature @nature über die Entdeckung des energiereichsten jemals beobachteten #Neutrinos. Seine Energie ist 16.000 Mal größer als die stärksten #Teilchenkollisionen des Large Hadron Colliders und entspricht dem 30-fachen der Energie, die zum Drücken einer Computertaste nötig ist.

Das Neutrino wurde in einem #Unterwasserobservatorium im Mittelmeer entdeckt, eines von insgesamt drei Neutrino-Detektoren im Wasser – zwei im Mittelmeer und einer am Baikalsee. Am geografischen Südpol gibt es den Neutrino-Detektor #IceCube unter dem Eis. Weitere Detektoren existieren unterirdisch in China, Italien und Japan.

Alle diese Detektoren befinden sich nicht auf der Erdoberfläche, da die Erde selbst wie ein #Teleskop für Neutrinos wirkt. Neutrinos sind extrem leichte, elektrisch neutrale #Teilchen, die kaum mit Materie wechselwirken und durch die Erde hindurchgehen. Bei Kollisionen mit Atomkernen entstehen geladene Teilchen, die schneller als Licht in Wasser oder Eis bewegen und dabei blaues Licht erzeugen, das erfasst wird.

Wasser und Eis sind ideale Medien, um Neutrinos nachzuweisen, da sie große Volumen bieten, um diese Teilchen zu entdecken und gleichzeitig kosmische Strahlung und Störungen abzuschirmen. IceCube nutzt sogar 1 Kubikkilometer Eis.

Neutrinos sind die zweithäufigsten Teilchen im #Universum, nach Photonen, aber schwer zu verstehen, da sie so wenig mit Materie interagieren. Interessanterweise interagieren auch dunkle Materie und dunkle Energie, die 95 % des Universums ausmachen, kaum mit normaler Materie, während die restlichen 5 % aus Elementen wie #Wasserstoff und #Helium bestehen, wovon nur 0,5 % sichtbare #Materie (wie Sterne) sind.
