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 ...
This layer is completely cloudless and free of water vapor. However, non-hydrometeorological phenomena such as the aurora borealis and aurora australis are occasionally seen in the thermosphere. The International Space Station orbits in this layer, between 350 and 420 km (220 and 260 mi). It is this layer where many of the satellites orbiting ...
Aurora borealis, or the northern lights, are seen Oct. 10 in Oxford, Iowa. The auroras are a natural light display in Earth's sky that are famously best seen in high-latitude regions of the ...
Aurora borealis explained According to Space.com , an aurora is created when the sun ejects charged particles from its upper atmosphere, creating a solar wind that slams "into Earth's upper ...
The purpose of the project is to monitor the frequency and intensity of the Aurora Borealis (Northern lights) in the years that led up to the Solar Maximum that was scheduled to occur in 2013-14. Scientists have noticed that the sun's activity follows a regular cycle and the peak (Solar maximum) is reached every 11 years.
The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
The thermosphere (or the upper atmosphere) is the height region above 85 kilometres (53 mi), while the region between the tropopause and the mesopause is the middle atmosphere (stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near an altitude of 45 kilometres (28 mi) and causes the ozone layer.
Here's where you may see aurora borealis from the geomagnetic storm forecast for Dec. 31. ... NASA reports that thanks to Earth’s magnetic field and atmosphere, residents are not directly harmed ...
