Auroras, known as the Northern or Southern Lights, are phenomena where the sky lights up with swirling patterns of colors, a result of charged particles from the sun colliding with the Earth's atmosphere. These displays are most common near the poles due to the Earth's magnetic field directin...
Research Associate Professor, Boston University's College of Engineering Toshi Nishimura was a co-author on the original STEVE research paper. Nishimura studies auroras, solar wind-magnetosphere-ionosphere interactions and upper atmosphere physics. What causes STEVE? STEVE is a glow of hot gas in ...
In the southern latitudes, it is known as Aurora Australis, Australis being the Latin word for “of the south”. Auroras seen near the magnetic pole may be high overhead, but from farther away, they illuminate the northern horizon as a greenish glow or sometimes a faint red. The auroras ...
according to science siteAtmospheric Optics. This causes light to ring the sun at a distance of 22degrees as sun-haloes. When the light is concentrated as spots next to the sun. also separated by 22 degrees it appears as sundogs.
What is lightning that occurs below the horizon or behind clouds called? Lightning Lightning is a naturally occurring phenomenon that releases one gigajoule of energy because of electrostatic discharge. There are three types of lightning: cloud to ground, cloud to air, and cloud to cloud. ...
arc and green picket fence are two distinct phenomena arising from different processes. The picket fence is caused by a mechanism similar to typical auroras, but STEVE's mauve streaks are caused by heating of charged particles higher up in the atmosphere, similar to what causeslight bulbsto ...
Get the ad-free experience for life Interplanetary medium also causes a number of phenomena including the zodiacal light, which appear as a faint broad band of light only seen before sunrise or after sunset. This light, brightest near the horizon, occurs when light bounces off dust particles ...
"Sleep paralysis can be a very frightening experience for some people, and a clear understanding of what actually causes it would have great implications for people who suffer from it," said Baland Jalal, a neuroscientist at the University of California, San Diego. ...
F."Electricity" is nitrogen/oxygen plasma created by an electric field.By this definition, whenever a spark jumps, we can say that "electricity" jumped too. By this definition, lightning, auroras, and St. Elmo's fire are examples of "electricity." This kind of "Electricity" is a bit lik...
different forms of radiation. In our own solar system, thesolar wind— charged particles that stream from the sun — emanate throughout the solar system and occasionally cause auroras near Earth's poles.Cosmic raysalso fly through our neighborhood, stemming from supernovas outside of the solar ...
