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...

Venus Transit Will Help RHESSI Improve Sun Measurements
2012-06-05 08:42:08

The RHESSI (Ramaty High Energy Solar Spectroscopic Imager) satellite focuses on the highest energy x-rays and gamma-rays produced by the sun, helping to observe solar flares of all shapes and sizes. The satellite is pointed toward the sun, and constantly in rotation, which provides a serendipitous bit of side research: by monitoring the limb of the sun on its four second rotation cycle, RHESSI´s Solar Aspect System (SAS) has produced ten years worth of precise measurements of the sun's...

Some Sun-like Stars Put Off Superflares
2012-05-17 13:32:04

New research shows that other sun-like stars in the universe can send off flares much larger than those seen on our sun. Solar flares are the result of broken magnetic-field loops as they pass through sunspots. As these loops become twisted and contorted, the flares occur, sending enormous amounts of charged particles, energy and radiation outward. So far, the largest solar flare ever measured on our sun happened on September 1, 1859, by British astronomer Richard Carrington. He simply...

Climatic Effects Of A Solar Minimum On Planet Earth
2012-05-07 05:00:52

Joshua Kelly for RedOrbit.com Researchers with the Helmholtz Association of German Research Centers are investigating a link between the massive solar minimum that occurred around 2800 years ago and the effects that it had on the climate of Europe.  They are still researching how the solar minimum could possibly impact the region of Europe in general. One thing they have been researching is information from Lake Maar to see how the sediment in the lake correlates to the solar minimum....

Hinode And SOHO Paint An Asymmetrical Picture Of The Sun
2012-04-23 04:36:24

Approximately every 11 years the magnetic field on the sun reverses completely — the north magnetic pole switches to south, and vice versa. It's as if a bar magnet slowly lost its magnetic field and regained it in the opposite direction, so the positive side becomes the negative side. But, of course, the sun is not a simple bar magnet and the causes of the switch, not to mention the complex tracery of moving magnetic fields throughout the eleven-year cycle, are not easy to map out....

Sun's Impact On Earth: What We Need To Know To Prepare For The Future
2012-03-15 05:17:31

Joshua Kelly, Meteorology Correspondent Redorbit.com If you recall back in the year 2000 we were being filled with this information of “global warming” occurring at record setting levels. However, did you also know that in 2009 there were reports of the glaciers in Montana gaining ground and expanding snow cover? So how is it possible that we are going into global warming and then magically just as of recently we now are being told that it´s “climate change.”...

Image 1 - 'Cool' Gas May Form And Strengthen Sunspots
2012-02-01 05:19:44

Hydrogen molecules may act as a kind of energy sink that strengthens the magnetic grip that causes sunspots, according to scientists from Hawaii and New Mexico using a new infrared instrument on an old telescope. "We think that molecular hydrogen plays an important role in the formation and evolution of sunspots," said Dr. Sarah Jaeggli, a recent University of Hawaii at Manoa graduate whose doctoral research formed a key element of the new findings. She conducted the research with Drs....

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...
