Direction Change For Interstellar Winds
2013-09-06 04:15:08

redOrbit Staff & Wire Reports - Your Universe Online Data obtained through NASA's Interstellar Boundary Explorer (IBEX) project has revealed that neutral interstellar atoms are flowing into the solar system from a different direction than previously observed. That information has led scientists affiliated with the mission to believe that those particles, which flow past the Earth as the solar system passes through the surrounding interstellar cloud at speeds of 23 kilometers per...

No Planetary Influence On Solar Activity
2013-09-05 14:37:53

Lee Rannals for redOrbit.com - Your Universe Online New research in Astronomy & Astrophysics (A&A) is correcting errors in one statistical study published in the same journal last yea,r regarding the isotopic records of solar activity. Last year, astronomers wrote in the journal claiming that there is evidence of planetary influence on solar activity. However, the latest study refutes that claim, saying that they found no evidence of any planetary effect on the Sun. The Sun...

Michigan Technological University Nanosatellites are smartphone-sized spacecraft that can perform simple, yet valuable, space missions. Dozens of these little vehicles are now tirelessly orbiting the earth performing valuable functions for NASA, the Department of Defense and even private companies. Nanosatellites borrow many of their components from terrestrial gadgets: miniaturized cameras, wireless radios and GPS receivers that have been perfected for hand-held devices are also...

Scientists Observe Magnetic Flow On The Sun
2013-08-28 19:43:38

Lee Rannals for redOrbit.com – Your Universe Online NASA's Solar Dynamics Observatory has helped scientists figure out a little more about what is going on inside the sun. The SDO has an instrument onboard known as the Helioseismic and Magnetic Imager (HMI). This instrument has allowed scientists to observe a two-level system of circulation within the sun. Understanding this circulation will be especially important in the coming months as the sun's magnetic poles flip. The sun is...

Another Earth-Directed Coronal Mass Ejection
2013-08-22 06:59:09

NASA On August 21, 2013 at 1:24 am EDT, the sun erupted with an Earth-directed coronal mass ejection, or CME, a solar phenomenon that can send billions of tons of particles into space and reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations Observatory show...

Auroras Recreated In The Lab
2013-08-22 05:08:58

April Flowers for redOrbit.com - Your Universe Online One of the most beautiful sights in North America is the Aurora Borealis, the famous Northern Lights. A team of scientists have discovered the tools necessary to recreate the colorful light show, and have brought the Northern Lights to a lab at NASA’s Langley Research Center. A device called the Planeterrella combines all the necessary ingredients - a magnetic field, charged particles, and a sphere – to create the simulation of...

NASA’s Solar Terrestrial Relations Observatory Sees An Earth Directed Coronal Mass Ejection

Air Force Scientists Share Insights About Lab-Created Ball Lightning
2013-08-20 13:15:52

Lee Rannals for redOrbit.com - Your Universe Online Ball lightning is a phenomenon that has puzzled some of the best minds for generations, including Aristotle and Nikola Tesla. Now, scientists from the US Air Force Academy say they have some new insights into reproducing the rare form of lightning in the laboratory. The phenomenon consists of a floating, glowing ball that drifts eerily through the sky and then explodes violently. It sometimes can injure people and damage buildings....

NASA’s dramatic video of a black-topped sun on the verge of flipping its magnetic polarity has captivated people. Friends of Science say the current low solar sunspot activity, not seen in 200 years, is a pattern that historically preceded global cooling and that the sun is the main driver of climate change, not carbon dioxide. Calgary, Alberta, Canada (PRWEB) August 15, 2013 Climate change on earth is significantly affected by the changing 11 year solar magnetic cycles, according to...

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...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
