Comet ISON May Or May Not Put On A Show
2013-11-18 15:55:32

[ Watch the Video: ISON Keeps Giving Us The Run-Around ] Alan McStravick for redOrbit.com - Your Universe Online I’ve been nerding out for most of the year, since Comet ISON first came on my radar, so to speak. Back in February, I wrote a piece for redOrbit detailing the discovery of a comet so magnificent that its show was going to be the stuff of legend. And then in July, redOrbit’s Brett Smith tried to rain on my astral parade when he reported on the diminished expectations...

Powering The SUn's Atmosphere
2013-11-15 09:30:08

John P. Millis, PhD for redOrbit.com - Your Universe Online The core of the Sun is a nuclear furnace, burning at 15 million degrees Kelvin. This heat travels to the surface, creating surface plasma that is still a balmy 6,000 Kelvin. However, a strange thing happens above the surface of the Sun; in the solar atmosphere, known as the corona, temperatures can exceed a million degrees Kelvin. Researchers have long suspected that the cause for this dramatic heating is due to interactions...

UPDATE (November 18, 2013 12:30 a.m. EST) At 11:48 a.m. EST, liquid oxygen began flowing into the Atlas first stage booster. Liquid oxygen loading of the Centaur upper stage is about 50 percent complete. There are no technical issues. Liftoff of a United Launch Alliance Atlas V rocket carrying NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft is targeted for the opening of a two-hour window at 1:28 p.m. from Space Launch Complex 41 in Florida. ------------------------...

Voyager 1 Probe Detects 'Interstellar Music'
2013-11-04 03:06:34

[ Watch the Video: Voyager 1 Encounters An Interstellar Love Song ] redOrbit Staff & Wire Reports - Your Universe Online There is no air in space, and there cannot be sound without air. So what did NASA researchers mean when they recently stated that they had detected “interstellar music” which provided strong evidence that Voyager 1 had left the magnetic bubble surrounding the sun and planets known as the heliosphere? That “interstellar music” is actually plasma waves...

How Were Biomolecules Able To Form Inside Asteroids?
2013-10-02 04:24:43

redOrbit Staff & Wire Reports - Your Universe Online Scientists from Rensselaer Polytechnic Institute (RPI) in New York have published new research which they claim definitively refutes existing theories as to how the biomolecules were able to form inside of asteroids. Wayne Roberge, a professor of physics at the RPI School of Science, and his colleagues state that they have developed a new theory based on a fuller, more complete understanding of magnetic fields and solar winds in...

WASHINGTON, Sept. 12, 2013 /PRNewswire-USNewswire/ -- NASA's Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars. Voyager is in a transitional...

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...

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...

IBEX First Images Heliosphere Tail
2013-07-10 13:08:59

[ Watch the Video: IBEX Provides First View of the Solar System’s Tail ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Interstellar Boundary Explorer (IBEX) spacecraft has unveiled an unexpected structure in the first complete pictures of the solar system's heliotail. Scientists believe a "tail" trails the heliosphere, which is the giant bubble in which our solar system resides. As the heliosphere moves through interstellar space, it creates a tail similar to that of a...

WASHINGTON, July 10, 2013 /PRNewswire-USNewswire/ -- Like a comet, the solar system has a tail. NASA's Interstellar Boundary Explorer (IBEX) has for the first time mapped out the structure of this tail, which is shaped like a four-leaf clover. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Scientists describe the tail, called the heliotail, based on the first three years of IBEX imagery in a paper published in the July 10 edition of the Astrophysical Journal. While...

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...

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...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...

Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...
