California Fires as Seen From the Space Station

The Earth, in all its majesty and its tragedy, is the subject of images taken aboard the International Space Station. This image of the Carr and Ferguson fires was captured from the station on August 3, 2018, by European Space Agency astronaut Alexander Gerst. via NASA https://ift.tt/2ALEef1

Live: Cosmic Rays from Minnesota

Cosmic rays from outer space go through your body every second. Typically, they do you no harm. The featured image shows some of these fast moving particles as streaks going through Fermilab’s NOvA Far Detector located in Ash River, Minnesota, USA. Although the image updates every 15 seconds, it only shows cosmic rays that occurred over a (changing) small fraction of that time, and mostly shows only one type of particle: muons. The NOvA Far Detector’s main purpose is not to detect cosmic rays, though, but rather neutrinos from the NuMI beam shot through the Earth from Fermilab near Chicago, Illinois, USA, 810 kilometers away. Only a few neutrino events are expected in NOvA per week, though. The NuMI / NOvA experiment is allowing humanity to better explore the nature of neutrinos, for example how frequently they change type during their trip. Cosmic rays themselves were discovered only about 100 years ago and can not only alter computer memory, but may have helped to create DNA mutations that resulted in, eventually, humans. via NASA https://ift.tt/2vnfeFR
