Near Miss: The Solar Superstorm Of July 2012

Dr. Tony Phillips, Science@NASA If an asteroid big enough to knock modern civilization back to the 18th century appeared out of deep space and buzzed the Earth-Moon system, the near-miss would be instant worldwide headline news. Two years...

April Flowers for redOrbit.com - Your Universe Online On July 14, NASA will launch a sounding rocket from White Sands Missile Range in New Mexico. A little before noon, the rocket will streak 180 miles into the atmosphere, sending it into the thermosphere layer, beyond the ozone's ability to block the sun's high energy light. Sounding rockets are small payload, scientific research rockets. Named for the nautical term "to sound," which means to take measurements, the rockets have been...

redOrbit Staff & Wire Reports - Your Universe Online In order to better understand what powers solar flares, NASA officials announced on Thursday that they were turning to the MESSENGER spacecraft orbiting Mercury in order to get a closer look at these intense bursts of radiation resulting from sunspot-related magnetic energy release. As the US space agency explained, it can be difficult understanding some of the processes on the sun when you are forced to rely solely upon the...

Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a mid-level solar flare, peaking at 12:20 p.m. EDT on July 8, 2014, and NASA's Solar Dynamics Observatory captured images of the event. 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...

Voyager 1 Entering Interstellar Space
2014-07-08 03:45:14

redOrbit Staff & Wire Reports - Your Universe Online A new “tsunami wave” generated by the sun has helped NASA scientists confirm that Voyager 1 is currently traveling through interstellar space, or the area between the stars that is filled with charged particles known as plasma, the US space agency reported on Monday. Waves like these are what initially led astronomers to conclude that the spacecraft had escaped the magnetic bubble surrounding the sun and planets known as the...

Early Sun's Violent Beginnings May Have Unlocked The Mystery Of Milky Way Meteorites
2014-07-01 14:36:46

Gerard LeBlond for redOrbit.com - Your Universe Online Observations of a Sun-like star through the Herschel Space Observatory may have unlocked the mystery of meteorites in our own galaxy, according to European Space Agency (ESA) astronomers. Astronomers are studying young stars in faraway areas of the galaxy, discovering they have a violent beginning, much as our own sun did 4.5 billion years ago. Herschel is surveying the chemical composition of stars being born and a team of...

IRIS Solar Observatory After 1 Year In Space

[ Watch The Video: A First For IRIS: Observing A Gigantic Solar Eruption ] Karen C. Fox, NASA On June 27, 2013, NASA's newest solar observatory was launched into orbit around Earth. The Interface Region Imaging Spectrograph, or IRIS, observes the low level of the sun's atmosphere -- a constantly moving area called the interface region -- in better detail than has ever been done before. During its first year in space, IRIS provided detailed images of this area, finding even more...

Gerard LeBlond for redOrbit.com - Your Universe Online [ Watch the Video: Plasma Simulation Of The Solar Wind And A Near-Earth Asteroid ] Space appears to be an endless vacuum void of sound, but it’s not. Electric activity not visible to the naked eye emerges from asteroids drifting through space, and NASA is now in the process of sending astronauts to an asteroid to explore its electrical environment. Solar winds from the sun travel through space about a million miles per hour and...

Sun Has Bad Weather Just Like On Earth
2014-06-26 03:31:08

Royal Astronomical Society Just like on Earth, the Sun has spells of bad weather, with high winds and showers of rain. But unlike the all-too-frequent storms of the UK and Ireland, rain on the Sun is made of electrically charged gas (plasma) and falls at around 200,000 kilometers an hour from the outer solar atmosphere, the corona, to the Sun's surface. And the thousands of droplets that make up a 'coronal rain' shower are themselves each as big as Ireland. Now a team of solar...

redOrbit Staff & Wire Reports - Your Universe Online [ Watch the Video: STEREO View Of Solar Atmosphere ] Astronomers using NASA’s Solar Terrestrial Relations Observatory (STEREO) have discovered that the atmosphere of solar particles surrounding the sun is larger than previously believed, extending out some five million miles above the surface, the US space agency announced on Wednesday. The solar atmosphere, which is also known as the corona, consists of particles “through...

Royal Astronomical Society (RAS) A suite of Sun-gazing spacecraft, SOHO, STEREO and Solar Dynamics Observatory (SDO), have spotted an unusual series of eruptions in which a series of fast 'puffs' force the slow ejection of a massive burst of plasma from the Sun's corona. The eruptions took place over a period of three days, starting on 17 January 2013. Images and animations of the phenomena were presented at the National Astronomy Meeting 2014 in Portsmouth by Nathalia Alzate on Monday 23...

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...

A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...

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...
