Movie Of Sun's Canyon Of Fire Released By NASA
2013-10-24 14:21:52

[ Watch The Video: Canyon of Fire on the Sun ] NASA A magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion. The 200,000 mile long filament ripped through the sun's atmosphere, the corona, leaving behind what looks like a canyon of fire. The glowing canyon traces the channel where magnetic fields held the filament aloft before the explosion.  Visualizers at NASA's Goddard Space Flight Center in Greenbelt, Md....

Drs. Michael Hahn and Daniel Wolf Savin, research scientists at Columbia University's Astrophysics Laboratory in New York, NY, found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona and moreover that they also deposit most of their energy at sufficiently low heights for the heat to spread throughout the corona. The observations help to answer a 70-year-old solar physics conundrum about the unexplained extreme temperature of the Sun's corona –...

The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to understand. Scientists use seismic waves - pulses of energy generated during earthquakes - to measure what is happening in the Earth's inner core, which at 6000 km beneath our feet is completely inaccessible. Problematically for researchers, the results of seismic measurements...

New science book looks at solar science and dissects it for an easier understanding. Mount Holly, Vt. (PRWEB) October 03, 2013 In “Grand Phases On The Sun: The case for a mechanism responsible for extended solar minima and maxima” (published by Trafford Publishing), author Steven Haywood Yaskell explains distinguished solar scientist Cornelis de Jager’s papers concerning whether or not the solar maximum for the solar cycle will be very strong or very weak. “Is there yet another...

TEPCO will deploy 27 million smart meters over the next 10 years. (Logo:...

How Were Biomolecules Able To Form Inside Asteroids?
2013-10-02 04:24:43

redOrbit Staff & Wire Reports - Your Universe Online Scientists from Rensselaer Polytechnic Institute (RPI) in New York have published new research which they claim definitively refutes existing theories as to how the biomolecules were able to form inside of asteroids. Wayne Roberge, a professor of physics at the RPI School of Science, and his colleagues state that they have developed a new theory based on a fuller, more complete understanding of magnetic fields and solar winds in...

Sun's Chromosphere Studied By Sunrise Mission
2013-09-28 04:29:37

April Flowers for redOrbit.com - Your Universe Online In June 2013, the solar observatory Sunrise was carried aloft by a NASA scientific balloon. Three months later, scientists from the Max Planck Institute for Solar System Research in Germany have presented unique insights into a layer on the sun called the chromosphere. The images from Sunrise are the highest-resolution ultraviolet light images to date of this thin corrugated layer, which lies between the sun's visible surface and the...

SARNIA, ON, Sept. 21, 2013 /CNW/ - Sun-Canadian Pipe Line confirms remediation plans are underway to repair the damage surrounding a pipeline leak which occurred on Tuesday, September 10. Traffic management plans are in place to ensure Vidal Street in Sarnia partially re-opens to the public beginning at 5 a.m. on Monday, September 23.  The company worked with the City of Sarnia, regulators and a number of contractors to ensure the road could re-open following a series of soil...

Sun Intensity Will End Life On Earth In No More Than 3.25 Billion Years
2013-09-19 10:33:04

[ Watch the Video: Earth Will Enter The Hot Zone In Several Billion Years ] Brett Smith for redOrbit.com - Your Universe Online In one of the longest range weather forecasts ever made, a team of UK scientists has determined that the sun’s growing intensity will lead to the evaporation of the oceans and end of life on Earth in about 1.8 to 3.2 billion years – according to a new report published in the journal Astrobiology. Using planets outside the Solar System and their stars as...

Researchers May Have Solved The Spin Mystery Of Earth's Core
2013-09-17 06:18:52

April Flowers for redOrbit.com - Your Universe Online For the last 300 years at least, we have been questioning what direction the center of the earth spins. A group of scientists from the University of Leeds, UK, and the Swiss Federal Institute of Technology may have found the answer. According to the study, published in Proceedings of the National Academy of Sciences (PNAS), the Earth's inner core - made of solid iron - "superrotates" in eastward directions. This means it spins faster...

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...
