Time magazine has called Byron Katie “a spiritual innovator for the new millennium,” and her School for The Work of Byron Katie teaches a simple yet powerful method of turning lives around. Unlike every other school on earth, this one isn´t for learning–it´s for unlearning. The nine days are focused on unraveling the fear-based stories people innocently cling to all their lives–stories like ”I´m not good enough,” “My husband should...

Largest-ever Magnetic Field Found Around Massive Star
2012-09-12 06:10:56

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have measured the largest-ever magnetic field around a massive star and reported their findings in the journal Monthly Notices of the Royal Astronomical Society. The team used the Hobby-Eberly Telescope (HET) at The University of Texas McDonald Observatory and the Canada-France Hawaii Telescope (CFHT) on Hawaii's Mauna Kea to determine that the star's magnetic field is 20,000 times stronger than the Sun's. The magnetic...

Galactic Center And The Pigtail Molecular Cloud
2012-09-05 11:06:34

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using a telescope at the National Astronomical Observatory of Japan have discovered a molecular cloud that has a peculiar helical structure. The team, led by Shinji Matsumura, a second year Ph. D. candidate, named it a "pigtail" molecular cloud due to its morphology. The pigtail molecular cloud is located in the galactic center, about 30,000 light years away from the solar system. Giant molecular clouds found in this...

Radiation From Sun’s Solar Whip Is Expected To Reach Earth Today

Watch the Video: Filament Eruption August 31, 2012 Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from NASA have discovered an enormous ℠solar whip´ on the surface of the Sun and have warned that radiation from the phenomenon is heading straight toward Earth, arriving on our doorstep sometime today. The stunning event was captured by NASA´s Solar Dynamics Observatory (SDO) and, according to a report from Mail Online´s Mark Prigg, video and...

IDEA! Coronal Mass Ejection From The Sun
2012-08-28 14:51:12

Watch the Video: Lightbulb Shaped CME Lee Rannals for redOrbit.com - Your Universe Online The sun sent off another coronal mass ejection (CME) last week, but this time the plasma burst showed up in the form of a light bulb. The Solar and Heliospheric Observatory (SOHO) caught the CME light bulb with its Large Angle and Spectrometric Coronagraph (LASCO) C2 instrument. This instrument is able to take images of the solar corona by blocking the light coming directly from the Sun with...

Solar Activity Linked To Colder European Winters
2012-08-24 05:50:24

April Flowers for redOrbit.com - Your Universe Online Scientists have long suspected that the Sun's 11-year cycle influences climate of certain regions on Earth. Records of average, seasonal temperatures do not date back far enough to confirm any patterns, though. An international team of researchers, armed with a unique proxy, show that unusually cold winters in Central Europe are related to low solar activity — when sunspot numbers are minimal. Germany's Rhine River freezing is...

Researchers reproduce plasma loops to help understand solar physics In orbit around Earth is a wide range of satellites that we rely on for everything from television and radio feeds to GPS navigation. Although these spacecraft soar high above storms on Earth, they are still vulnerable to weather–only it's weather from the sun. Large solar flares–or plasma that erupts from the sun's surface–can cause widespread damage, both in space and on Earth, which is why researchers...

Magnetic Turbulence Could Cause Solar Wind Temperature Rise
2012-08-19 06:44:46

redOrbit Staff & Wire Reports - Your Universe Online Magnetic turbulence is most likely the reason that solar wind moving away from our sun and our solar system is hotter than it theoretically should be, according to new research from scientists at the University of Warwick. As solar wind leaves the sun and expands beyond the solar system, it should begin to cool off due to the lack of particle collisions to dissipate energy, the university explained in a Friday press release. That...

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...
