Dr. Petrus Martens, a professor in the Department of Physics and Astronomy at Georgia State University, has received a three-year, $1.2 million NASA Grand Challenge grant to develop a system to predict solar cycles and determine the long-term frequency of events such as solar flares, potentially more than a decade in advance. (PRWEB) September 10, 2014 Dr. Petrus Martens, a professor in the Department of Physics and Astronomy at Georgia State University, has received a three-year, $1.2...

migration tracks on the sun

Karen C. Fox, NASA's Goddard Space Flight Center Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun’s activity, known as solar maximum, is a time of numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space. However, the timing of the solar cycle is far from precise. Since humans began regularly recording sunspots in the 17th...

April Flowers for redOrbit.com - Your Universe Online On July 14, NASA will launch a sounding rocket from White Sands Missile Range in New Mexico. A little before noon, the rocket will streak 180 miles into the atmosphere, sending it into the thermosphere layer, beyond the ozone's ability to block the sun's high energy light. Sounding rockets are small payload, scientific research rockets. Named for the nautical term "to sound," which means to take measurements, the rockets have been...

solar mini-max
2014-06-11 11:02:39

Brett Smith for redOrbit.com - Your Universe Online Our Sun is constantly cycling between periods of low activity and high activity – known as solar minimum and solar maximum, or Solar Max, respectively. In 2008 and 2009, NASA’s solar experts reported they were surprised to see the Sun descend into one of its deepest solar minimums in recorded history. But now, NASA observers are saying that the solar minimum is almost over. [ Watch the Video: ScienceCasts: Solar Mini-Max ]...

New Jersey Institute of Technology The 1.6 meter telescope at Big Bear Solar Observatory (BBSO) in California has given researchers unparalleled capability for investigating phenomena such as solar flares. Operated by New Jersey Institute of Technology (NJIT), the BBSO instrument is the most powerful ground-based telescope dedicated to studying the star closest to Earth. On June 2, Distinguished Professor of Physics Haimin Wang joined NJIT colleagues at the 224th meeting of the...

Intense Solar Storm Narrowly Misses Earth
2014-05-02 15:33:50

[ Watch The Video: ScienceCasts: Carrington-Class CME Narrowly Misses Earth ] Science@NASA Last month (April 8-11), scientists, government officials, emergency planners and others converged on Boulder, Colorado, for NOAA's Space Weather Workshop—an annual gathering to discuss the perils and probabilities of solar storms. The current solar cycle is weaker than usual, so you might expect a correspondingly low-key meeting. On the contrary, the halls and meeting rooms were abuzz...

Sun Emits Mid Level Solar Flare Jan. 7, 2014
2014-01-07 12:11:43

NASA The sun emitted a mid-level solar flare, peaking at 5:13 a.m. EST on Jan. 7, 2014. Images of the flare were captured by NASA's Solar Dynamics Observatory and showed that it came from an active region on the sun that currently sports one of the largest sunspots seen in the last 10 years. Sunspots are regions of strong and complex magnetic fields on the sun's surface. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere...

As ice storms put much of Ontario into the cold and dark for Christmas, Friends of Science are citing a recent report by Dr. Madhav Khandekar that indicates cold weather extremes are on the rise; this trend is under reported in the media, and virtually unnoticed by climate researchers at the IPCC. Friends of Science say the sun is the main driver of climate change, not carbon dioxide, and that solar cycles are exhibiting abnormal patterns. Calgary, Alberta, Canada (PRWEB) December 26,...

Mars Surface Radiation Suitable Manned Mission
2013-12-10 15:24:46

Brett Smith for redOrbit.com - Your Universe Online Newly released data from the Curiosity rover indicate that Martian radiation levels are very close to being acceptable for future manned missions to the surface of the Red Planet. While the Curiosity rover spent its first 300 days cruising around the planet’s Gale Crater gathering soil samples and examining rock structures, the onboard Radiation Assessment Detector (RAD) was making detailed recording of the radiation found on the...

Magnetic Field Lines

[ Watch the Video: The Sun's Changing Magnetic Field ] redOrbit Staff & Wire Reports - Your Universe Online A newly-released NASA visualization shows the process of the sun’s magnetic field changing polarity, with the positive and negative poles switching throughout the course of the 22 year magnetic solar cycle. According to Karen C. Fox of the Goddard Space Flight Center, the magenta colored lines represent regions where the overall field is negative, while the green lines...

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 Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
