"With our new generation visible imaging spectrometer (VIS), the solar...

Solar Flip Soon
2013-08-06 13:41:02

Brett Smith for redOrbit.com - Your Universe Online [ Watch the Video: Preparing For The Solar Max Magnetic Flip ] Solar experts are anticipating a major event that is about to happen within the next three or four months - the sun is going to flip. Every eleven years, the Sun reaches the peak of its cycle and proceeds to switch polarity, making north become south and south become north. NASA scientists said the upcoming change will also mark the halfway point of solar max, a period...

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

NASA At NASA's White Sands Test Facility in Las Cruces, N.M., a sounding rocket is being readied for flight. Due to launch on Aug. 8, 2013, the VERIS rocket, short for Very high Resolution Imaging Spectrometer, will launch for a 15-minute trip carrying an instrument that can measure properties of the structures in the sun's upper atmosphere down to 145 miles across, some eight times clearer than any similar telescope currently in space. When it comes to observing the sun, different...

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

Lee Rannals for redOrbit.com - Your Universe Online Tel Aviv University (TAU) scientists developed a new tool to measure climate change by using radio waves. 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. The team wrote in the Journal of...

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

ESA 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. Orbiting in space since 1999, XMM-Newton is studying high-energy phenomena in the Universe, such as black holes, neutron stars, pulsars and stellar winds. Even when moving from object to object, the space telescope collects data. These slews are represented by the bright...

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

Lee Rannals for redOrbit.com - Your Universe Online NASA's Interface Region Imaging Spectrograph (IRIS) has provided scientists with their first look at the Sun's atmosphere. On July 17, an international team of scientists and engineers working on IRIS saw their hard work pay off when the telescope provided its first glimpse, showing unprecedented detail of a little-observed region of the sun. "These beautiful images from IRIS are going to help us understand how the sun's lower...

WASHINGTON, July 25, 2013 /PRNewswire-USNewswire/ -- NASA's Interface Region Imaging Spectrograph (IRIS) spacecraft has captured its first observations of a region of the sun that is now possible to observe in detail: the lowest layers of the sun's atmosphere. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The first images from IRIS show the solar interface region in unprecedented detail. They reveal dynamic magnetic structures and flows of material in the sun's...

AlphaGalileo Foundation Exploring the extreme Universe with a rich new resource Three years' research led by University of Leicester Department of Physics and Astronomy Team produces new catalogue with 531,261 detections of X-ray emitting objects - a new record 372,728 unique X-ray sources identified The total area covered on the sky by the combined observation fields is -1400 square degrees Scientists led by the University of Leicester have set a new record for cosmic X-ray...

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

NASA 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. Experimental NASA research models based on observations from NASA's Solar Terrestrial Relations Observatory, or STEREO, show that the CME was not Earth-directed, but may pass Mars.  It left the sun at around 715 miles per second, which is a fairly fast speed...

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

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...
