New Program Aims To Understand Effects Of Space Weather
2013-07-01 19:10:36

Lee Rannals for redOrbit.com -- Your Universe Online Scientists are working on a program to better understand how national grids could be affected by space weather. British Geological Survey (BGS) researchers are conducting continuous measurements of the background electric field in the UK to better understand how the UK National Grid can be interrupted by the Sun. Space weather can take place when the ejection of material from the Sun, or coronal mass ejection (CME), shoots towards...

The images, which were scheduled to be presented by University of Central Lancashire professor Robert Walsh at the...

NASA IRIS Launch Successful
2013-06-27 18:15:59

[ Watch the Video: IRIS Launch ] Lee Rannals for redOrbit.com – Your Universe Online NASA successfully launched its new Interface Region Imaging Spectrograph (IRIS) aboard an Orbital Sciences Pegasus XL rocket at approximately 7:27 pm (PST) tonight. IRIS and the Pegasus rocket were both flown aboard Orbital's Stargazer L-1011 commercial transport aircraft, which has been modified to serve as the launch platform. This launch design helps to keep the cost low for smaller missions,...

Voyager 1 Still Within The Confines Of Solar System
2013-06-27 15:36:08

Lee Rannals for redOrbit.com - Your Universe Online Scientists are split on exactly where NASA's Voyager 1 spacecraft is sitting within the Solar System, but new research from the space agency suggests it is on the last frontier out. A team of scientists wrote in Geophysical Research Letters in March that the spacecraft had already left our Solar System. However, the latest intel from NASA shows that the spacecraft is still sitting just within the edge of our "Solar Bubble."...

NASA’s IRIS Solar Mission Launch Moved To Thursday
2013-06-25 03:10:20

[ Watch the video IRIS Science Overview ] Lee Rannals for redOrbit.com - Your Universe Online Update (June 25, 2013 3:10 p.m.) NASA announced on Tuesday that its planned launch for its Interface Region Imaging Spectrograph (IRIS) mission has been moved due to the "recent central California power outage." The launch window has moved from Wednesday, June 26 to Thursday, June 27. Stay tuned for further updates. Main Story (June 24, 2013 12:43 p.m.) NASA's Interface...

Sounding Rockets Will Help NASA Study Earth's Ionosphere
2013-06-21 13:42:41

Brett Smith for redOrbit.com - Your Universe Online Way up in the Earth’s atmosphere is a layer of charged particles called the ionosphere, which plays a crucial role in the transmission of radio and other signals. Through a mission called Dynamo, NASA scientists are planning to study the currents that pass through this charged section of the atmosphere found between 30 and 600 miles above Earth. Launching from NASA’s Wallops Flight Facility in Virginia, Dynamo is expected to take a...

Suck It Up! Sun Provides Insight Into How Young Stars Grow
2013-06-21 04:26:50

April Flowers for redOrbit.com - Your Universe Online Our Sun erupted on June 7, 2011, sending tons of hot plasma blasting into space. Some of the plasma fell back to the surface of the Sun, sparking bright flashes of ultraviolet light. A new study from the Harvard-Smithsonian Center for Astrophysics (CfA) examines the dramatic event to provide new insights into how young stars grow by consuming nearby gas. NASA's Solar Dynamics Observatory captured the eruption and subsequent...

NuSTAR Observatory Busy High Energy Events
2013-06-18 11:08:53

Brett Smith for redOrbit.com - Your Universe Online NASA´s NuSTAR orbiting observatory is designed to investigate high-energy events throughout the universe, and the cosmos has been keeping it busy in recent months, producing one event after another. In early April, the galaxy Markarian 421 produced a high-energy event that increased its brightness by more than 50 times its usual level. Markarian 421 is known as a blazer, a unique class of galaxies with supermassive "feeding" black...

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...
