IRIS Spotted Its Largest Solar Flare In January
2014-02-22 05:28:40

[ Watch the Video: IRIS Spots Its Largest Solar Flare ] April Flowers for redOrbit.com - Your Universe Online The strongest solar flare since NASA's Interface Region Imaging Spectrograph (IRIS) launched in the summer of 2013 was observed on January 28 of this year. Solar flares are bursts of X-rays and light that stream out into space, disrupting long-range radio transmission on Earth and satellite functions in space. What sets them off, however, is still a mystery for scientists....

Sun's Coronal Mass Ejections Behave Like Crab Nebula's Gas Tendrils
2014-02-21 13:28:29

[ Watch the Video: Enormous Coronal Mass Ejection ] Lee Rannals for redOrbit.com - Your Universe Online Researchers from University College London have explained for the first time the details of how the Sun’s coronal mass ejections (CMEs) behave when falling back onto the star’s surface. The team has discovered that coronal mass ejections are a lot like the tendrils of gas in the Crab Nebula, which are about 6,500 light-years away from Earth and are millions of times larger....

Ribbon Discovery At Edge Of Solar System Points To Influences From The Galactic Magnetic Field
2014-02-13 14:44:15

Lee Rannals for redOrbit.com - Your Universe Online NASA’s Interstellar Boundary Explorer (IBEX) discovered an enigmatic “ribbon” of energetic particles at the edge of our Solar System and a new study says it may be just a glimpse into how vast the influence of the galactic magnetic field really is. The galactic magnetic field around our solar system’s giant bubble, known as the heliosphere, determines the orientation of the ribbon and the placement of energetic particles...

redOrbit Staff & Wire Reports - Your Universe Online Burnt-bone charcoal, a pigment once used as part of prehistoric cave paintings in southern France, will be applied to the ESA’s Solar Orbiter to help protect the vehicle from the Sun’s rays, the agency announced Wednesday. The spacecraft, which is currently scheduled to launch in 2017, will have a type of black calcium phosphate produced from the substance applied to the outermost titanium sheet of its multilayered heatshield,...

Lunar Transit Seen By NASA's Solar Dynamics Observatory
2014-01-30 13:36:48

Karen C. Fox - NASA's Goddard Space Flight Center, Greenbelt, Md. On Jan 30, 2014, beginning at 8:31 a.m EST, the moon moved between NASA’s Solar Dynamics Observatory, or SDO, and the sun, giving the observatory a view of a partial solar eclipse from space. Such a lunar transit happens two to three times each year.  This one lasted two and one half hours, which is the longest ever recorded. When the next one will occur is as of yet unknown due to planned adjustments in SDO's orbit....

First X-class Flare Of 2014 Unleashed By The Sun
2014-01-08 10:55:47

[ Watch The Video: SDO Captures Release of X1.2 Class Solar Flare ] NASA Update: January 8, 2014 The Jan. 7, 2014, X-class flare was also associated with a coronal mass ejection, or CME, another solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. The European...

NASA's Solar Dynamics Observatory Sees Giant Sunspots
2014-01-08 07:21:33

NASA An enormous sunspot, labeled AR1944, slipped into view over the sun's left horizon late on Jan. 1, 2014. The sunspot steadily moved toward the right, along with the rotation of the sun, and now sits almost dead center, as seen in the image above from NASA's Solar Dynamics Observatory. Sunspots are dark areas on the sun's surface that contain complex arrangements of strong magnetic fields that are constantly shifting. The largest dark spot in this configuration is approximately two...

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...
