Astronomers Discover Solar Wind Energy Source
2013-03-08 12:36:32

NASA Science Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later this decade when it sends a new probe into the sun for a closer look. The discovery was made by a group of astronomers trying to solve a decades-old mystery: What heats and accelerates the solar wind? The solar wind is a hot and fast flow of magnetized gas that streams...

Twin Peaks For Solar Cycle?
2013-03-02 07:29:34

redOrbit Staff & Wire Reports - Your Universe Online While 2013 is supposed to be the year of Solar Max - the peak of the 11-year sunspot cycle - the relatively low solar activity recorded thus far has led experts to conclude that an unusual phenomenon has occurred. This most recent solar cycle has had not one but two peaks. According to NASA, sunspot numbers during the months of January and February 2013 were well below values recorded back in 2011. Furthermore, they report that...

SORCE Satellite Outlasts Mission Life And Keeps On Truckin'
2013-01-24 13:13:38

Lee Rannals for redOrbit.com — Your Universe Online Some missions in space complete their operations just after predicted, while others earn the Iron Man award for outlasting their primary mission. In the case of SORCE--a satellite designed to study solar storms--it's earned itself an Iron Man. Solar Radiation and Climate Experiment (SORCE), designed and built by the University of Colorado, is a NASA satellite that gives scientists a look at some of the most intense solar...

How Solar Activity Affects Our Planet
2013-01-10 11:02:17

NASA Science In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle. There is, however, a dawning realization among researchers that even these apparently tiny variations can have a significant effect on terrestrial climate. A new report issued by the National...

Solar Flare Heads Towards Earth
2012-11-13 15:54:05

Lee Rannals for redOrbit.com - Your Universe Online NASA said that the sun emitted a mid-level solar flare on Tuesday that has the potential of causing some radio blackouts. The solar flare reached a classification of M6, which falls into the weakest flares that are still able to cause some space weather effects near Earth. According to the National Oceanic and Atmospheric Association's Space Weather Scales, this M-class flare can cause a radio blackout categorized as R2, or...

Upcoming Total SOlar Eclipse To Be Documented
2012-11-05 13:25:40

Lee Rannals for redOrbit.com — Your Universe Online Australians will have the privilege of witnessing a total solar eclipse about an hour after sunrise on November 14. The eclipse will be visible from the northeastern Australia coast, along the Great Barrier Reef, during which astronomers will be working on scientific observations. Jay Pasachoff, Field Memorial Professor of Astronomy at Williams College, will be viewing his 56th solar eclipse, along with colleagues and...

NASA Observatory Captures Another X-Class Solar Flare
2012-10-23 15:32:34

[WATCH VIDEO: Active Region On The Sun Emits Another Flare] Lee Rannals for redOrbit.com — Your Universe Online NASA said its Solar Dynamics Observatory (SDO) captured the sun erupting with an X1.8 class solar flare on Monday. The solar flare came from an active region on the left side of the sun known as AR 1598, which has been the source of weaker flares. The "X-class" solar flares are the most intense flares, with the number near the X representing its intensity. An X2...

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...

Whilst the most powerful earthquake since records began hit Japan in 2011, triggering a massive tsunami which devastated much of the country, space scientists involved in one of the 'brightest' international Sun missions continued working tirelessly at the Institute of Space and Astronautical Science in Sagamihara, Japan, to capture new data from our turbulent star. These latest Hinode results, to be discussed in a meeting at the University of St Andrews this week (Tuesday 14 August),...

Doppler Techniques Could Help Predict Solar Storms
2012-07-04 04:12:19

Lee Rannals for redOrbit.com - Your Universe Online Scientists are using Doppler techniques that may be able to take predicting space weather to a new level and understanding. An international team of researchers have combined Doppler techniques with images and data from a space-based telescope to observe loops of 1,800,000-degree Fahrenheit plasma flowing up from the sun's surface at more than 12 miles per second. These loops arch over the sun, and may be the first signs of trouble...

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...

Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
