The first ever extra-solar auroras were discovered in July 2015 over the brown dwarf star LSR J1835+3259. [105] The mainly red aurora was found to be a million times brighter than the northern lights, a result of the charged particles interacting with hydrogen in the atmosphere.
Aurora during a geomagnetic storm that was most likely caused by a coronal mass ejection from the Sun on 24 May 2010, taken from the International Space Station. Auroras were seen around the world in the northern and southern hemispheres.
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.

[110] [111] 1752 – Benjamin Franklin conducts his kite experiment, successfully extracting sparks from a cloud, showing that lightning bolts are huge natural electrical discharges ...
The G5 level is the most extreme level possible. The aurora borealis could become visible tonight over much of the northern half of the U.S. and could reach as far south as Alabama.
Galileo [9] [10] discovered the Galilean moons. These satellites were the first celestial objects that were confirmed to orbit an object other than the Sun or Earth. Galileo saw Io and Europa as a single point of light on 7 January 1610; they were seen as separate bodies the following night. [11] Callisto: Jupiter IV o: 8 January 1610 p: 13 ...
