Extreme Space Weather In 2012 Resulted In Fastest Solar Wind Speed Ever Recorded
2014-03-19 05:25:02

[ Watch the Video: STEREO Captures Fastest CME to Date ] redOrbit Staff & Wire Reports - Your Universe Online Researchers have uncovered the origin and cause of an extreme space weather event that took place July 22, 2012 on the sun which generated the fastest solar wind speed ever recorded directly by a solar wind instrument. The formation of the powerful event showed remarkable features as a massive cloud of solar material erupted off the sun's right side, zooming out into...

Mid-Level Solar Flare Seen By NASA's Solar Dynamics Observatory
2014-03-13 12:05:22

Karen C. Fox, NASA The sun emitted a mid-level solar flare, peaking at 6:34 p.m. EDT on March 12, 2014, and NASA's Solar Dynamics Observatory, or SDO, captured an image of it. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event may...

Space Weather Shielding Provided By Plasma Plumes
2014-03-07 05:41:48

April Flowers for redOrbit.com - Your Universe Online The magnetosphere, Earth's magnetic field, stretches from the core of the planet out into space. Here, the magnetosphere meets the solar wind, a stream of charged particles emitted by the sun. The magnetosphere, for the main part, acts to shield the Earth from this high-energy solar activity. When the Earth's magnetosphere comes into contact with the sun's magnetic field in a process called "magnetic reconnection," the Earth's...

2014-03-01 05:57:56

Karen C. Fox, NASA's Goddard Space Flight Center A giant sunspot – a magnetically strong and complex region on the sun's surface – has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation. Scientists track sunspots that are part of active regions, which often produce large explosions on the sun such as solar flares and coronal mass ejections, or CMEs. Each time an active...

April Flowers for redOrbit.com - Your Universe Online A new superpowered small black hole, called MQ1, has been discovered by a team of Australian and American astronomers who were studying nearby galaxy M83. MQ1 is the first object of its kind to be studied in this much detail. Previously, astronomers have found a few compact objects as powerful as MQ1, but they have been unable to calculate the size of the black hole contained within until now. Using multiple telescopes, the team's...

X-class solar flare
2014-02-25 08:24:39

[ Watch the Video: SDO Observes Strong X-class Solar Flare ] Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a significant solar flare, peaking at 7:49 p.m. EST on Feb. 24, 2014. NASA's Solar Dynamics Observatory, which keeps a constant watch on the sun, captured images of the event. Solar flares are powerful bursts of radiation, appearing as giant flashes of light in the SDO images. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically...

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....

Space Weather Around Venus Is Harsher Than That Around Earth
2014-02-21 14:01:57

[ Watch the Video: What's Causing Crazy Weather On Venus? ] Lee Rannals for redOrbit.com - Your Universe Online According to a study published in the Journal of Geophysical Research, space weather around Venus is much harsher than what is experienced around Earth. Scientists have discovered that the space weather around Venus can have such large explosions that they are bigger than the entire planet. They also said that these giant explosions can happen multiple times per day....

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....

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...

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...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Ring Current
2004-10-19 04:45:44

Ring Current -- A ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10-200 keV) particles. Earth's Ring Current Earth's ring current is responsible for geomagnetic storms. The ring current system consists of a band, at a distance of 3-5 RE(1), which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region...
