Twin Star Insights Into Sun's Future
2013-08-28 13:47:51

[ Watch the Video: The Life Cycle of a Sun-Like Star ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have identified what they are calling the Sun's oldest twin, HIP 102152, sitting 250 light-years away from us. A team of astronomers using the European Southern Observatory's (ESO) Very Large Telescope (VLT) found that HIP 102152 is older but otherwise nearly identical to our Sun, giving astronomers a chance to see how our local star will look as it ages. Our Sun is...

NASA’s dramatic video of a black-topped sun on the verge of flipping its magnetic polarity has captivated people. Friends of Science say the current low solar sunspot activity, not seen in 200 years, is a pattern that historically preceded global cooling and that the sun is the main driver of climate change, not carbon dioxide. Calgary, Alberta, Canada (PRWEB) August 15, 2013 Climate change on earth is significantly affected by the changing 11 year solar magnetic cycles, according to...

Has Voyager 1 Finally Left The Solar System? New Analysis Reveals Compelling Evidence
2013-08-15 13:47:59

Brett Smith for redOrbit.com - Your Universe Online According to a new analysis from scientists at the University of Maryland, NASA's Voyager 1 has finally left the Solar System – marking the first time a man-made object has entered the Milky Way outside of the Sun’s influence. "It's a somewhat controversial view, but we think Voyager has finally left the Solar System, and is truly beginning its travels through the Milky Way," said study author Marc Swisdak, a UMD plasma physicist....

Stunning Solar Images From Big Bear
2013-08-07 08:51:48

April Flowers for redOrbit.com - Your Universe Online New and remarkably detailed photos of the Sun have been obtained by researchers at the New Jersey Institute of Technology's (NJIT) Big Bear Solar Observatory (BBSO) in Big Bear, California, with the New Solar Telescope (NST). Never-before-seen details of solar magnetism revealed in photospheric and chromospheric features are observed in these new photographs. "With our new generation visible imaging spectrometer (VIS), the solar...

Solar Flip Soon
2013-08-06 13:41:02

Brett Smith for redOrbit.com - Your Universe Online [ Watch the Video: Preparing For The Solar Max Magnetic Flip ] Solar experts are anticipating a major event that is about to happen within the next three or four months - the sun is going to flip. Every eleven years, the Sun reaches the peak of its cycle and proceeds to switch polarity, making north become south and south become north. NASA scientists said the upcoming change will also mark the halfway point of solar max, a period...

Sounding Rocket Getting Ready To Study Active Regions On The Sun
2013-08-03 07:59:17

NASA At NASA's White Sands Test Facility in Las Cruces, N.M., a sounding rocket is being readied for flight. Due to launch on Aug. 8, 2013, the VERIS rocket, short for Very high Resolution Imaging Spectrometer, will launch for a 15-minute trip carrying an instrument that can measure properties of the structures in the sun's upper atmosphere down to 145 miles across, some eight times clearer than any similar telescope currently in space. When it comes to observing the sun, different...

Heavy Metal Stars
2013-08-01 14:00:20

Lee Rannals for redOrbit.com - Your Universe Online Astronomers from the Armagh Observatory in Northern Ireland say they have discovered two unusual, heavy metal stars. The team wrote in the journal Monthly Notices of the Royal Astronomical Society that they found the stars HE 2359-2844 and HE 1256-2738 to contain extremely high concentrations of lead in their atmospheres. Naslim Neelamkodan, Simon Jeffery, Natalie Behara and Alan Hibbert said these two stars have surfaces containing...

The NPD Group, Inc., a global information company, reports sales of makeup and skincare with SPF reached $1.1 billion in US prestige department stores from June 2012 – May 2013, a 24 percent increase from three years ago. Port Washington, New York (PRWEB) July 25, 2013 “Whether it is health concerns, or a more superficial fear of looking older, the intensified focus on sun protection from the beauty and health care industries is having a real impact on consumers, and the market,”...

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...
