Researchers Use NASA And Other Data To Look Into The Heart Of A Solar Storm

Karen C. Fox, NASA's Goddard Space Flight Center A space weather storm from the sun engulfed our planet on Jan. 21, 2005. The event got its start on Jan. 20, when a cloud of solar material, a coronal mass ejection or CME, burst off the sun and...

April Flowers for redOrbit.com - Your Universe Online As children, we are told never to look directly at the Sun, especially through the lens of a camera, telescope or magnifying glass. Even if a person used the special filters that would allow them to gaze at the Sun, they would not be able to see all of the wavelengths of light emanating from the Sun. To fully understand our star, scientists must use spacecraft that can observe this invisible light before it is absorbed by the...

WASHINGTON, Aug. 18, 2014 /PRNewswire-USNewswire/ -- Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The signals have helped astronomers identify an unusual midsize black hole called M82 X-1, which is the brightest X-ray source in a galaxy known as Messier 82. Most black holes...

redOrbit Staff & Wire Reports - Your Universe Online Astronomers from the University of Maryland and NASA’s Goddard Space Flight Center in Greenbelt, Maryland have accurately measured and confirmed the existence of a black hole roughly 400 times the mass of our sun. Black holes that range in size from about 10 to 100 times the mass of our sun are the remnants of dying stars, while much larger supermassive black holes are more than one million times our sun’s mass and typically...

University of Maryland and NASA astronomers used rhythmic flares of light to measure a brilliant object 12 million light years from Earth, confirming that it is a rare, mysterious intermediate-mass black hole. (PRWEB) August 17, 2014 The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black...

April Flowers for redOrbit.com - Your Universe Online An extreme and rare event in the region of space immediately surrounding a supermassive black hole has been captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. The corona of the black hole, a compact source of X-rays that is situated nearby, has moved closer to the black hole over a period of just days. "The corona recently collapsed in toward the black hole, with the result that the black hole's intense gravity...

Karen C. Fox, NASA's Goddard Space Flight Center Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun's outer atmosphere so much hotter than its surface. The new observations of the small-scale extremely hot temperatures are consistent with only one current theory: something called nanoflares – a constant peppering of impulsive bursts of heating, none of which can be individually detected -- provide the mysterious extra heat. [ Watch:...

April Flowers for redOrbit.com - Your Universe Online University of Bristol’s professor of Aerospace Engineering Ashley Dale cautions that “solar super-storms” are going to cause “catastrophic” and “long-lasting” impacts if we continue to ignore the threat of such storms. Dale is a member of the international task force SolarMAX, which was designed to identify the risks of a solar storm and how humanity could minimize the risks. He believes that a particularly violent...

April Flowers for redOrbit.com - Your Universe Online For decades, scientists have been debating over a fog of low-energy X-rays that has been observed over the entire sky. An international group of scientists has used a NASA-funded instrument to resolve this debate. The group refurbished detectors that were first flown on a NASA sounding rocket in the 1970s to confirm that much of this glow is generated by a region of million-degree interstellar plasma known as the local hot bubble (LHB)....

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 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

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...
