The Sun undergoes a type of seasonal variability with its activity waxing and waning over the course of nearly two years, according to new research led by NCAR.

Our Sun goes through a few activity cycles and a new study has identified one such cycle that is almost seasonal in nature. According to the report, published in the journal Nature Communications, the nearly two-year cycle appears to be caused by shifts in the bands of powerful magnetic fields in each solar hemisphere. These bands also aid in shaping and approximately 11-year solar cycle that is part of a lengthier cycle that lasts approximately 22 years.

NASA and the ESA are hoping that a pair of satellites currently in development will solve some of the longstanding mysteries of the sun by getting up close and personal with our solar system’s host star, provided they can survive the extreme heat and harsh conditions.

Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...

Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:

Solar Flare -- A solar flare is a violent eruption that explodes from a star's photosphere with energies equivalent to tens of millions of hydrogen bombs. Solar flares from the Sun send out a streams of highly energetic solar wind that can present a radiation hazard to spacecraft outside of planetary magnetospheres and can disrupt radio signals on Earth. Solar flares were first observed on the Sun in 1859 by English astronomer Richard Carrington. They have also been observed to...

The Sun -- intensely hot, self-luminous body of gases at the center of the solar system. Its gravitational attraction maintains the planets, comets, and other bodies of the solar system in their orbits. The sun is actually a star of about medium size; it appears larger than the other stars because of its relative nearness to the earth. The earth's distance from the sun varies from 91,377,000 mi (147,053,000 km) at perihelion to 94,537,000 mi (152,138,000 km) at aphelion (see apsis). The...
