Sounding Rocket Getting Ready To Study Active Regions On The Sun
2013-08-03 07:59:17

At NASA's White Sands Test Facility in Las Cruces, N.M., a sounding rocket is being readied for flight.

New Tool Uses Radio Waves To Predict Climate Change
2013-07-31 11:15:23

The ionosphere is a region in the upper atmosphere that plays a vital role for global communications. This region is used for the transmission of long wave communications, such as radio waves, and now scientists have found waves from the ionosphere offer valuable news about climate change.

XMM-Newton's Dance Of The X-rays
2013-07-29 08:36:40

Like car tail lights streaking through a busy city at night, this unique image records over a thousand movements made by ESA's XMM-Newton space telescope as it shifts its gaze from one X-ray object to another.

IRIS offers first images of sun atmosphere
2013-07-25 15:10:18

NASA's Interface Region Imaging Spectrograph (IRIS) has provided scientists with their first look at the Sun's atmosphere.

New Record Set By Team From University of Leicester For Cosmic X-ray Sightings
2013-07-23 12:03:43

Scientists led by the University of Leicester have set a new record for cosmic X-ray sources ever sighted -- creating an unprecedented cosmic X-ray catalogue that will provide a valuable resource allowing astronomers to explore the extreme Universe.

Coronal Mass Ejection Witnessed By NASA's STEREO
2013-07-23 08:59:36

On July 22, 2013, at 2:24 a.m. EDT, the sun erupted with a coronal mass ejection or CME, a solar phenomenon that can send billions of tons of solar particles into space that can affect electronic systems in satellites.

SOHO Video Shows Eruptions On Sun

A new video posted by the European Space Agency (ESA) shows two solar eruptions taking place side-by-side.

Large Coronal Hole Near the Sun's North Pole
2013-07-22 08:58:30

The European Space Agency/NASA Solar and Heliospheric Observatory, or SOHO, captured this image of a gigantic coronal hole hovering over the sun's north pole on July 18, 2013, at 9:06 a.m. EDT.

Scientists Study Magnetic Reconnection Effects On Space Weather
2013-07-16 16:03:08

Using observations from two different NASA spacecraft, scientists have shed new light on the process behind solar flares and eruptions: magnetic reconnection.

Stellar Astrophysics

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
2012-05-02 19:16:53

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...
