NASA's SDO Captures Image Of Mid-level Solar Flare
2013-10-24 12:46:59

The sun emitted a mid-level solar flare that peaked at 8:30 pm EDT on Oct. 23, 2013.

Drs. Michael Hahn and Daniel Wolf Savin, research scientists at Columbia University's Astrophysics Laboratory in New York, NY, found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona and moreover that they also deposit most of their energy at sufficiently low heights for the heat to spread throughout the corona.

Naked Jets Of Water Is A Better Way To Detect Pollutants

When you shine ultraviolet light (UV) through water polluted with certain organic chemicals and bacteria, the contaminants measurably absorb the UV light and then re-emit it as visible light.

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

Scientists from Rensselaer Polytechnic Institute 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.

Sun's Chromosphere Studied By Sunrise Mission
2013-09-28 04:29:37

In June 2013, the solar observatory Sunrise was carried aloft by a NASA scientific balloon. Three months later, scientists from the Max Planck Institute for Solar System Research in Germany have presented unique insights into a layer on the sun called the chromosphere.

Space Weather Origins Revealed
2013-09-27 04:21:43

Research published in Friday’s issue of the journal Science looks to shed new light on how changing environmental conditions in near-Earth space known as “space weather” can occur.

coma cluster of galaxies
2013-09-20 04:46:30

In the Coma cluster of galaxies, enormous arms of hot gas that span at least a half a million light years have been discovered. Scientists say these findings could provide insight into how the Coma cluster has grown to become one of the largest structures in the Universe held together by gravity.

Voyager 1 Has Left Solar System, Reaching New Horizons
2013-09-12 13:57:02

Man has officially embarked on a new adventure that surpasses Lewis and Clark's excursion across the US, as NASA's Voyager 1 spacecraft officially reaches interstellar space.

Iron In The Sun
2013-09-06 08:00:37

Scientists from the Heidelberg Max Planck Institute for Nuclear Physics (MPIK) in cooperation with DESY (Hamburg) at the synchrotron PETRA III have investigated for the first time X-ray absorption of highly charged iron ions.

Stellar Astrophysics

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
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...

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...
