auroras occur on the Antarctic continent itself or over the surrounding oceans andland fringeswhere few people are located. While in the northern hemisphere, the lights occur over highly populated areas so are seen more frequently, such as in the northern Norwegian town ofKirkenesseen in figure 1...
So we found that during CMEs—with their enormous ejections of particles from the Sun—auroras are particularly intense. Now, as we’ve said, we can predict peaks in sunspot activity, but so far we can’t say the same for CMEs. ...
The Norwegian city is also one of the best places to watch the Northern Lights, aka auroras. 4. There's an Arctic Council In 1996, the Ottawa Declaration established the Arctic Council to decide on matters about the region. The Arctic States are all part of the forum. "The Council ...
Red auroras are comparatively less frequent and are usually associated with intense solar activity. They occur when solar particles react with oxygen at higher altitudes, generally around 180 to 250 miles (300 to 400 km), according to the CSA. At this height, oxygen is less concentrated and ...
Introduction to the aurora borealis or northern lights The northern lights are also called "aurora borealis", or simply "auroras". The "northern" part of the name is because they occur along the North Pole. That said, these lights appear in both polar regions, in the Northern and Southern ...
Auroras occur in the ionosphere where high-energy particles from the sun interacting with the atoms in this layer. An aurora borealis over the Pacific Northwest in the United States. Image:NASA astronaut Scott Kellytaken from the International Space Station, January 20, 2016. ...
— Auroras over Earth: Amazing northern lights photos from space— What is the solar wind? Auroras occur on other planets, too — all that's required to make an aurora is an atmosphere and a magnetic field. "Auroras have been seen in the atmospheres of all the gas giant planets, which ...
Seeing the northern lights in Scandinavia is something you never forget. Learn how auroras occur, where and when to see them, and other handy viewing tips.
It is a nearly spherical body, and it emits energy in the form of electromagnetic radiation caused by a nuclear fusion reaction at the sun's core. Its radius is about 110 times the radius of the Earth, and its mass is about 330 thousand times the mass of the Earth. The sun makes ...
What makes the sky blue?Colloidal Chemistry:The subject which involves studies of the chemical nature, reactions and characteristics of colloidal substances is colloidal chemistry. Colloids are the particles which have relatively larger size than atoms of elements and are usually found suspended in a ...
