Scientists Spots Giant Space Weather Effects At Mercury
2014-06-16 03:32:22

Karen C. Fox, NASA The solar wind of particles streaming off the sun helps drive flows and swirls in space as complicated as any terrestrial weather pattern. Scientists have now spotted at planet Mercury, for the first time, a classic space weather event called a hot flow anomaly, or HFA, which has previously been spotted at Earth, Venus, Saturn and Mars. "Planets have a bow shock the same way a supersonic jet does," said Vadim Uritsky at NASA's Goddard Space Flight Center in...

redOrbit Staff & Wire Reports - Your Universe Online If there are cracks on the ice-covered surface of Charon, an upcoming analysis of those fractures could help determine whether or not the interior of Pluto’s moon was warm enough to have been home to a subterranean ocean of liquid water. In April, research funded by the US space agency and published in the journal Icarus reported how tidally-driven fractures could have formed on the moon if its orbit was previously eccentric....

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Dating the formation of the Earth is a difficult process, because usually geological dating methods do not work as well. Early in its existence the Earth was more fluid, with materials all mixing together in a super-heated mix. It took millions of years for differentiation and cooling to achieve the layered Earth we live on today. So traditional geological dating gives us more of a lower bound for the age of the Earth, while...

Earth's Magnetosphere Doesn't Stop All Solar Wind From Breaking Through
2014-06-11 14:41:29

Brett Smith for redOrbit.com - Your Universe Online Using data from four European Space Agency satellites that fly in formation in the Earth's magnetic field, researchers have uncovered new information on how the solar wind can break through the Earth’s magnetosphere and disrupt modern life. According to a new report in the journal Physical Review Letters, when the solar wind meets the environment around the Earth – an electromagnetic phenomenon called an asymmetric magnetic...

3 x-class flares
2014-06-11 08:40:19

UPDATE - June 11, 2014 On June 11, 2014, the sun erupted with its third X-class flare in two days. The flare was classified as an X1.0 and it peaked at 5:06 a.m. EDT.  Images of the flare were captured by NASA's Solar Dynamics Observatory. All three flares originated from an active region on the sun that recently rotated into view over the left limb of the sun. ----- UPDATE - June 10: The sun released a second X-class flare, peaking at 8:52 a.m. EDT on June 10, 2014.  This is...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Despite being the nearest astronomical object to Earth, and the only extraterrestrial site of human visitors, the Moon still contains mysteries that have puzzled scientists for the better part of a century. Perhaps the greatest question surrounding lunar history is its two-faced nature. Due to the mutual gravitational interaction of the Earth-Moon system, the giant satellite is tidally locked with our planet, so we always see...

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...
