WASHINGTON, Sept. 12, 2013 /PRNewswire-USNewswire/ -- NASA's Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars. Voyager is in a transitional...

[ Watch the Video: Are We There Yet? NASA Says Yes ] Lee Rannals for redOrbit.com - Your Universe Online 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. The US space agency announced on Thursday that after traveling through space for 36 years, the probe has finally ventured out into interstellar space, becoming the first man-made object to travel beyond our...

SARNIA, ON, Sept. 11, 2013 /CNW/ - Sun-Canadian Pipe Line shut its pipeline in the area of Vidal St. and Churchill Rd. in Sarnia after instrumentation detected a release of ultra low sulphur diesel (ULSD). Sun-Canadian's monitoring system immediately alerted staff who rapidly responded with the closing of the line. As a precaution, another portion of Sun-Canadian's line was also closed. Local industry rallied to support in the containment of the release through the Chemical...

Direction Change For Interstellar Winds

redOrbit Staff & Wire Reports - Your Universe Online Data obtained through NASA's Interstellar Boundary Explorer (IBEX) project has revealed that neutral interstellar atoms are flowing into the solar system from a different direction than previously observed. That information has led scientists affiliated with the mission to believe that those particles, which flow past the Earth as the solar system passes through the surrounding interstellar cloud at speeds of 23 kilometers per...

No Planetary Influence On Solar Activity
2013-09-05 14:37:53

Lee Rannals for redOrbit.com - Your Universe Online New research in Astronomy & Astrophysics (A&A) is correcting errors in one statistical study published in the same journal last yea,r regarding the isotopic records of solar activity. Last year, astronomers wrote in the journal claiming that there is evidence of planetary influence on solar activity. However, the latest study refutes that claim, saying that they found no evidence of any planetary effect on the Sun. The Sun...

Scientists Observe Magnetic Flow On The Sun
2013-08-28 19:43:38

Lee Rannals for redOrbit.com – Your Universe Online NASA's Solar Dynamics Observatory has helped scientists figure out a little more about what is going on inside the sun. The SDO has an instrument onboard known as the Helioseismic and Magnetic Imager (HMI). This instrument has allowed scientists to observe a two-level system of circulation within the sun. Understanding this circulation will be especially important in the coming months as the sun's magnetic poles flip. The sun is...

Twin Star Insights Into Sun's Future

[ 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....

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...
