Aurora Borealis Beret | AllFreeKnitting.com. In the Middle Ages, scientists came up with other guesses as to what was behind the northern lights: they suggested that the light of the aurora was sunlight reflected by ice crystals in the air, the glow of glacier ice near the pole, or a light emanating from the edge of Earth.

Though it was Italian astronomer Galileo Galilei who coined the name "aurora borealis" in 1619 after the Roman goddess of dawn, Aurora, and the Greek god of the north wind, Boreas the earliest suspected record of the northern lights is in a 30,000-year-old cave painting in France (opens in new tab).

The Doppler effect for light emission causes a shortening of the wavelength of the emission if the emitting atom or molecule is moving toward the observer, and a lengthening of the wave-length if it is moving away. 
Gauge: 30sts and 38 rows = 10 cm 10 cm Abbreviations: When a solar storm comes toward us, some of the energy and small particles can travel down the magnetic field lines at the north and south poles into Earth's atmosphere. The oxygen atom has an excited state for this red line emission with a mean lifetime of 100 seconds, and only at very high altitudes are collisions infrequent enough to allow this radiation to be emitted (Figure 9).

It is common to have very bright red auroral displays during such large storms. north carolina discovery objections / jacoby ellsbury house Even though auroras are best seen at night, they are actually caused by the Sun. For example, researchers weren't entirely sure how the energized particles in the solar wind get accelerated to their extraordinary speeds (45 million mph) until June 2021, when a study published in the journal Nature Communications (opens in new tab) confirmed that a phenomenon called Alfvn waves gave the particles a boost. The NASA Hubble Space Telescope took this picture of an aurora on Jupiter using ultraviolet (UV) light. 2008) shows that the wind is affected by the aurora as the direction and speed changes right at the position of the auroral curtain.
