On January 25–26, 1938, the sky was lit up with an aurora borealis light storm, seen all across the world. The storm was identical to other storm-induced, low-latitude aurora borealis. The great aurora that was witnessed across Europe, the Americas, and Oceania had not been seen/documented in Europe since 1709, and in the Americas since 1888.
An aurora [a] (pl. aurorae or auroras), [b] also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), [c] is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains ...
Cherenkov radiation glowing in the core of the Advanced Test Reactor at Idaho National Laboratory. Cherenkov radiation (/ tʃ ə ˈ r ɛ ŋ k ɒ f / [1]) is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium (such as distilled water) at a speed greater than the phase velocity (speed of propagation of a wavefront in a medium) of ...
Millions were wowed last week when the Northern Lights, or Aurora Borealis, made a rare appearance as far south as the Gulf Coast.. Photos circulated on social media and elsewhere of the pink and ...
The northern lights are a colorful effect caused by energized particles from the sun that are redirected toward the poles when they collide with Earth's magnetic field, according to NASA.
The particularly unique thing about Steve is that it looks somewhat like a line instead of the more typical oval you get with traditional auroras. It can also be seen from space, according to NASA.
The blue sky spectrum contains light at all visible wavelengths with a broad maximum around 450–485 nm, the wavelengths of the color blue. Diffuse sky radiation is solar radiation reaching the Earth 's surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere .
Tips for viewing the northern lights "Go out at night," NOAA said. "And get away from city lights." The best aurora is usually within an hour or two of midnight (between 10 p.m. and 2 a.m. local ...
