What causes the different colors?The color of the aurora is dependent upon the wavelength of the emitted light. It is similar to a fluorescent lamp where the color depends upon which gas in the atmosphere is involved and what state the molecules are in. When solar energetic particles enter ...
You’ve probably seen a bunch of news articles about an unusual solar event making the aurora visibleas far down as the southern US.If you want just a short answer as to what causes the aurora, it’s just solar flares. But how does it allwork,and if you took a look outside, you ...
Since an atmosphere and a magnetic field are all required to make an aurora, this celestial display can also occur on other planets. This phenomenon has been observed in the atmosphere of all the gas giant planets, and it is not surprising considering these planets all have strong magnetic...
When the sun is active, however, the aurora borealis can be seen across southern Canada and the northern United States.What aspect of the auroras does the class mainly discuss?The class mainly discusses what causes the auroras. The professor says The auroras are the result of a complex ...
Here we learn what causes the different colors in the aurora borealis (northern lights) and the aurora australis (southern lights).
Aurora is a natural light display in Earth's sky, primarily seen in high latitude regions, caused by solar winds disturbing the magnetosphere. Nebulae are vast clouds of gas and dust in space, often the birthplace of stars, visible as luminous patches.
Steve Ackerman, a professor of Atmospheric and Oceanic Sciences at the University of Wisconsin-Madison,reckonsthat several variables must coincide for this spectacular phenomenon to occur. A fire rainbow is one of the few types of halos formed by the refraction of light in plate-shaped ice crysta...
”poleward arcs” stretching sunward across the polar cap, the related “theta aurora”, and “dayside arcs” near noon. These are relatively infrequent and poorly understood. Other interesting effects occur such as flickering aurora, “black aurora” and subvisual red arcs. ...
The northern lights, also known as aurora borealis, are one of the biggest reasons travellers flock to northern Scandinavia in winter. Like shape-shifting apparitions dancing across the stars, this is an experience you’ll never forget. Of course, spotting this awe-inspiring natural phenomenon requ...
An article from thehomeschoolscientist.com says; Frost quakes are very shallow seismic events, unlike earthquakes that are caused by the moving of tectonic plates deep within the Earth's crust." When Do Frost Quakes Happen? For frost quakes to occur, temperatures need to go from above ...
