Magnetic Field Model Of Sun Explains Solar Activity Cycles

Since the 18th Century, scientists have been aware that the Sun oscillates between periods of high and low solar activity in an 11-year cycle. So far, though, they have been unable to fully explain how this cycle is generated.

M-Class Solar Flare And Two Coronal Mass Ejections Detected Mid-Week
2013-05-23 07:00:42

As the peak year of the solar maximum picks up in intensity, NASA’s Solar Dynamics Observatory (SDO) observed yet another solar flare and two coronal mass ejections (CMEs) mid-week.

NASA Is Readying IRIS Spacecraft For Launch In June

IRIS will help advance scientists understanding of the interface region, which is an area in the lower atmosphere of the sun where most of the sun's ultraviolet emissions are generated. Emissions from this area impact the near-Earth space environment and Earth's climate.

Our knowledge of how stars evolve arises out of our survey of billions of stars within and outside of our galaxy. As we piece together the snapshots of these stars of various sizes and masses, at various stages of their evolution, we begin to get a complete picture of how stars are born, live, and die.

Coronal Mass Ejection Heads Toward Earth This Weekend

On May 17, the sun unleashed an Earth-directed coronal mass ejection (CME) at 5:24 a.m. EDT sending billions of tons of solar particles into space. The matter from this CME will likely reach Earth in one to three days and potentially affect electronic systems in satellites and on the ground.

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...

Solar Physics is a journal for solar and solar-stellar research and the study of solar terrestrial physics. Founded in 1967 by solar physicist Cornelis de Jager and publisher D. Reidel, the journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution, to outer corona and solar wind in interplanetary space. Solar Physics has four more than forty years been the principal journal for publications of fundamental research on the Sun. It is...

The spectroheliograph captures a photographic image of the Sun at a single wavelength of light. The wavelength chosen usually coincides with a spectral wavelength of one of the chemical elements present in the Sun. George Ellery Hale and Henri-Alexadre Deslandres developed I independently in 1890 and was further refined in 1932 by Robert R. McMath to take motion pictures. It operates by using a prism together with a narrow slit that passes a single wavelength. The light focuses on a...

bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
The word 'bretelles' comes from a French word meaning 'braces'.
