A solar flare is an intense burst of electromagnetic radiation generated in the sun's atmosphere — the layers of sparse but hot gas that lie above its visible surface, or photosphere. The vast amounts of energy released by a typical solar flare are mostly radiated away in the ultraviolet...
Solar eclipses are perhaps the most dazzling celestial phenomena that you can see clearly from Earth. A solar eclipse occurs when the Earth,moonandsunare aligned in the same plane, and the moon passes between theEarthand the sun. During a total solar eclipse, the moon completely covers the ...

Sunrise industries often represent a new way of approaching an old issue. For example, alternative energy in the form of wind and solar power was a sunrise industry in the 2000s, replacing coal and other nonrenewable sources of energy. ...
“It can be dangerous if we aren’t careful, but it’s also very safe if we take the basic precautions,” said Dr. Geoffrey Emerson, a board member of the American Society of Retina Specialists, told NBC ofthe danger. Sunglasses are NOT equipped to protect your vision for the solar ecl...
c) total solar eclipses would last much longer. You're an astronomer studying the origin of the solar system, and you're evaluating the hypothesis that small particles (rock/dust) were blown out of the solar system by the radiation pressure of sunl How large is ...
