Suck It Up! Sun Provides Insight Into How Young Stars Grow
2013-06-21 04:26:50

Our Sun erupted on June 7, 2011, sending tons of hot plasma blasting into space. Some of the plasma fell back to the surface of the Sun, sparking bright flashes of ultraviolet light. A new study examines the dramatic event to provide new insights into how young stars grow by consuming nearby gas.

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

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...
