NASA Sun Observer Captures Two Solar Eruptions Over Four Hours
2012-11-17 15:28:22

[ Watch the Video: Double Prominence Eruptions ] Lawrence LeBlond for redOrbit.com - Your Universe Online On November 13, the Sun emitted an M6 classification solar flare, one of the weakest designations still able to cause some disturbances on Earth. Now, just a few days later, the Sun is at it again. NASA´s Solar Dynamic Observatory (SDO) caught spectacular images and video of the Sun bursting with two prominence eruptions over a four-hour period on November 16, between the...

Proba-2 Veiwed Three Solar Eclipses Last Night
2012-11-14 11:22:33

[ Watch The Video ( 1 ) ]   [ Watch The Video ( 2 ) ] ESA ESA´s Sun-watching Proba-2 satellite experienced three partial solar eclipses last night while lucky observers watching from northern Australia were treated to a total solar eclipse. During a total solar eclipse, the Moon moves in front of the Sun as seen from Earth, their alignment and separation such that the much closer Moon appears large enough to block out the light from the much more distant Sun....

Solar Flare Heads Towards Earth
2012-11-13 15:54:05

Lee Rannals for redOrbit.com - Your Universe Online NASA said that the sun emitted a mid-level solar flare on Tuesday that has the potential of causing some radio blackouts. The solar flare reached a classification of M6, which falls into the weakest flares that are still able to cause some space weather effects near Earth. According to the National Oceanic and Atmospheric Association's Space Weather Scales, this M-class flare can cause a radio blackout categorized as R2, or...

Are You Ready For A Total Solar Eclipse?
2012-11-13 10:24:35

ESA Tomorrow´s total solar eclipse will only be visible in its entirety to ground-based observers watching from northern Australia, but ESA´s Sun-watching Proba-2 satellite will have a ringside seat from its orbit around Earth. During a total solar eclipse the Moon moves in front of the Sun as seen from Earth, their separation and alignment such that the Moon appears large enough to temporarily block out the Sun´s light. An eerie light is cast over ground observers as...

Upcoming Total SOlar Eclipse To Be Documented
2012-11-05 13:25:40

Lee Rannals for redOrbit.com — Your Universe Online Australians will have the privilege of witnessing a total solar eclipse about an hour after sunrise on November 14. The eclipse will be visible from the northeastern Australia coast, along the Great Barrier Reef, during which astronomers will be working on scientific observations. Jay Pasachoff, Field Memorial Professor of Astronomy at Williams College, will be viewing his 56th solar eclipse, along with colleagues and...

Birth Record Of Our Solar System Revised
2012-11-03 05:43:41

redOrbit Staff & Wire Reports - Your Universe Online The formative stages of the Milky Way, once believed to have taken far longer to occur than other solar systems, may not have been as unique as scientists had previously thought, according to the authors of a new study. Writing in the journal Science, researchers from the Centre for Star and Planet Formation at the Natural History Museum of Denmark, University of Copenhagen report they have discovered a pair of vastly different...

Solar Spacecraft Celebrate Six Years In Service
2012-10-29 03:50:29

redOrbit Staff & Wire Reports - Your Universe Online On Thursday, October 25, NASA's twin Solar Terrestrial Relations Observatory (STEREO) program celebrated its sixth anniversary orbiting the sun, the US space agency announced on Friday. The twin orbiting probes were launched on that date in 2006, and ultimately entered into similar but separate orbits around the sun. STEREO-A's orbit is slightly smaller and faster, while STEREO-B's is larger and slower, they said, and those subtle...

Could Our Sun Eventually Devour Earth?
2012-10-26 14:50:20

NASA Science [ Watch The Video ] An international team of astronomers has caught a star in the act of devouring one of its planets. BD+48 740, a red giant they observed using the 9.2-meter Hobby-Eberly Telescope at the McDonald Observatory in Texas, appears to have the fumes of a scorched planet in its atmosphere. This is consistent with a rocky world, recently destroyed. Could the same thing happen to Earth? Yes indeed, says Alex Wolszczan, a member of the research team from Penn...

NASA Observatory Captures Another X-Class Solar Flare
2012-10-23 15:32:34

[WATCH VIDEO: Active Region On The Sun Emits Another Flare] Lee Rannals for redOrbit.com — Your Universe Online NASA said its Solar Dynamics Observatory (SDO) captured the sun erupting with an X1.8 class solar flare on Monday. The solar flare came from an active region on the left side of the sun known as AR 1598, which has been the source of weaker flares. The "X-class" solar flares are the most intense flares, with the number near the X representing its intensity. An X2...

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...

Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...

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...

The spectroheliograph captures a photographic image of the Sun at a single wavelength of light. The wavelength chosen usually coincides with a spectral wavelength of one of the chemical elements present in the Sun. George Ellery Hale and Henri-Alexadre Deslandres developed I independently in 1890 and was further refined in 1932 by Robert R. McMath to take motion pictures. It operates by using a prism together with a narrow slit that passes a single wavelength. The light focuses on a...
