PALO ALTO, Calif., June 17, 2013 /PRNewswire/ -- The Interface Region Imaging Spectrograph (IRIS) spacecraft is on track for a launch from Vandenberg Air Force Base in California on June 26. IRIS will fill a crucial gap in the ability of scientists to advance Sun-Earth connection studies by tracing the flow of energy and plasma through a dynamic interface region - the chromosphere and transition region - between the solar surface and the solar corona. "The entire IRIS team is...
GREENBELT, Md., June 14, 2013 /PRNewswire-USNewswire/ -- A new study by astronomers at NASA, Johns Hopkins University and the Rochester Institute of Technology confirms long-held suspicions about how stellar-mass black holes produce their highest-energy light.

NASA The sun emitted a mid-level solar flare, peaking at 6:49 p.m. on June 7, 2013. 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 communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours. This flare is classified as an...
PALO ALTO, Calif., June 10, 2013 /PRNewswire/ -- On December 15-16, 2011, a Sun-grazing comet, designated Lovejoy (C/2011 W3), passed deep within the hot solar atmosphere - the corona - effectively probing a region that could never be visited by spacecraft because of the intense heat radiating from the nearby solar surface. In a paper published today in the journal Science, researchers from several institutions - including the Solar & Astrophysics Lab at the Lockheed Martin...
John P. Millis, PhD for redOrbit.com – Your Universe Online As telescopes peer into the distant background of the Universe they are, in effect, looking back in time. The light emitted from these objects has been traveling across the Universe for perhaps billions of years. So by analyzing the background light of the sky researchers can get a picture of the composition of the Universe early in its evolution. New data from NASA’s Chandra X-ray Observatory and NASA’s infrared Spitzer...
April Flowers for redOrbit.com - Your Universe Online Scheduled to launch June 26, NASA’s newest scientific satellite will provide the most detailed look ever at the sun’s lower atmosphere, called the interface region. The interface region is located between the sun’s visible surface and upper atmosphere. This is where most of the sun’s ultraviolet emissions, which impact the near-Earth space environment and Earth’s climate, are generated. NASA’s new Interface Region Imaging...
Brett Smith for redOrbit.com - Your Universe Online The Max Planck Institute for Solar System Research (MPS) in Germany has announced the upcoming launch of its balloon-based solar observatory Sunrise after its team performs one last ground-based test. Outfitted with the biggest solar telescope to have ever left the Earth's surface, a helium-filled balloon will lift Sunrise 2 almost 22 miles above the ground where it will begin observations of the Sun. Four years ago, Sunrise’s...
redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) have blended science, technology and art to create a unique new website that allows people to listen to original musical compositions crafted from cosmic x-rays. The Star Songs website was published by research associate Gerhard Sonnert, who worked with University of Glasgow postdoctoral student Wanda Diaz-Merced and composer Volkmar Studtrucker on the project....
New trucks for CAB law in Corona, California. 2012 or newer for the fleet of Acclaimed Corona Movers Corona, California (PRWEB) May 28, 2013 The city of Corona’s first choice for residential and commercial moving services, Acclaimed Corona Movers, has just added new trucks to offer improved local moving. The new, twenty-four foot, box trucks, which come equipped with lift-gates, greatly improve the efficiency and availability of Acclaimed’s local moving services. Additionally, the...

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...
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 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 -- 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...
