Black Holes Abundant Early Universe
2013-06-06 14:16:28

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...

NASA Prepares IRIS Satellite For Solar Observing Mission
2013-06-05 06:37:32

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...

Balloon Solar Observatory Sunrise Ready To Launch
2013-06-04 11:52:36

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,...

Star Songs Plucked From The Cosmos
2013-06-01 05:44:51

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...

Magnetic Field Model Of Sun Explains Solar Activity Cycles
2013-05-23 08:32:58

April Flowers for redOrbit.com - Your Universe Online Since the 18th Century, scientists have been aware that the Sun oscillates between periods of high and low solar activity in an 11-year cycle. So far, though, they have been unable to fully explain how this cycle is generated. Understanding the Sun´s magnetic activity has become increasingly important as we rely more on our electronic devices. Changes in the magnetic field are responsible for “space weather”...

M-Class Solar Flare And Two Coronal Mass Ejections Detected Mid-Week
2013-05-23 07:00:42

Lawrence LeBlond for redOrbit.com - Your Universe Online As the peak year of the solar maximum picks up in intensity, NASA´s Solar Dynamics Observatory (SDO) observed yet another solar flare and two coronal mass ejections (CMEs) mid-week. On Wednesday May 22 the sun emitted an M7 solar flare, which peaked at about 9:38 a.m. EDT. While it was not immediately clear if the M-class flare also produced a CME, NASA confirmed later that the flare was associated with a CME. While this CME...

NASA Is Readying IRIS Spacecraft For Launch In June
2013-05-21 15:40:18

[WATCH VIDEO: 'IRIS Readies For A New Challenge' Mission Trailer] Lee Rannals for redOrbit.com — Your Universe Online NASA is getting ready to launch a new mission in June this year called the Interface Region Imaging Spectrograph (IRIS). IRIS will help advance scientists understanding of the interface region, which is an area in the lower atmosphere of the sun where most ultraviolet emissions are generated. Emissions from this area impact the near-Earth space environment and...

Coronal Mass Ejection Heads Toward Earth This Weekend
2013-05-19 07:37:21

[WATCH VIDEO: Coronal Mass Ejection On May 17, 2013] Lawrence LeBlond for redOrbit.com - Your Universe Online On May 17, the sun unleashed an Earth-directed coronal mass ejection (CME) at 5:24 a.m. EDT sending billions of tons of solar particles into space. The matter from this CME will likely reach Earth in one to three days and potentially affect electronic systems in satellites and possibly the International Space Station (ISS). NASA research models based on observations from...

Jets Powered By A Black Hole Plow Into Galaxy
2013-05-16 07:56:30

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Astronomy is more than merely using optical telescopes to take pretty pictures of distant nebulae and galaxies. Researchers also seek to understand complex systems in the universe by observing how objects interact and what types of radiation are produced. To do this requires telescopes capable of observing over several energy bands, working together to construct a complete physical picture of the object of interest....

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
