Volcano and Aurora
Volcano and Aurora in Iceland Image Credit & Copyright: Sigurdur H. Stefnisson Explanation: Sometimes both heaven and Earth erupt. In Iceland in 1991, the volcano Hekla erupted at the same time that auroras were visible overhead. Hekla, one of the most famous volcanoes in the world, has erupted at least 20 times over the past…

Message Sent Through Rock Via Neutrino Beam
See:Cern Courier:The right spin for a neutrino superfluid If like myself you are watching the history of communication, it becomes important to understand the advances we have on the horizon for when we are looking across the expanse of space for consideration of that information transference. MINERvA: Bringing Neutrinos into Sharp Focus Like radio…

Relativistic Time Dilation in Muon Decay
According to Einstein’s special theory of relativity, a clock moving at a significant fraction of the speed of light with respect to an observer runs more slowly than the observer’s own clock. This implies that time must be flowing more slowly in a moving frame of reference, which is referred to as time dilation. If…

Muons reveal the interior of volcanoes
The location of the muon detector on the slopes of the Vesuvius volcano. Like X-ray scans of the human body, muon radiography allows researchers to obtain an image of the internal structures of the upper levels of volcanoes. Although such an image cannot help to predict ‘when’ an eruption might occur, it can, if combined…
