John P. Millis, Ph.D. for redOrbit.com – Your Universe Online While our solar system contains many fascinating objects – planets, moons and the Sun, to name just a few – one of the most interesting and perplexing of these objects lies at its very edge. Our Sun sweeps charged particles through the solar system, encasing us in a cocoon that shields us from the interstellar environment. It is at the boundary of the solar system, where the solar wind slows and the influence of our...

Lee Rannals for redOrbit.com – Your Universe Online While solar wind is a common occurrence in our Solar System, a study of a new, more fierce wind has been completed using the European Space Agency's XMM-Newton space observatory. These massive stellar winds derive from rare, giant stars which burn their nuclear fuel more rapidly than stars like the Sun, and that live for millions of years before exploding into a supernova. Massive stars lose a significant fraction of their mass...

WESTON, Fla., Feb. 5, 2013 /PRNewswire-iReach/ -- Last month's launch of a new UV LED stain detector in flashlight form should make squeamish hotel visitors rest a little easier. The product, called Hotel Inspector(TM), makes use of ultraviolet light technology to help detect residue from such biological matter as saliva, urine, blood residue, feces, vomit and semen on sheets, towels, carpeting and other surfaces. Since nobody wants to find these things in a hotel room, the...

Lee Rannals for redOrbit.com – Your Universe Online One who didn't know better would think that the closer you get to the sun, the warmer you are. However, it is actually the outer edge of the sun that you would find to be scorching, compared to the surface, and one study sought to find out why. Scientists from Northumbria University wrote in the journal Nature Communications that they used solar-imaging technology to observe the Sun's chromosphere, which is a region of the Sun's...

HiViz LED Lighting solution with Instant-On/Instant-Off would not have delayed the Super Bowl due to power outage. Raleigh, NC (PRWEB) February 04, 2013 The power outage at the Super Bowl causing the lights to go through a 34-minute recycle to warm up which delayed the game could have been completely avoided using the HiViz Field and Stadium LED lighting technology. “Our LED stadium light solutions change the game completely compared to traditional metal halide lighting as is installed...

NASA [ Watch The Video ] On Jan. 31, 2013 at 2:09am EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA’s Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 575 miles per second, which is a fairly typical speed for CMEs. Historically, CMEs at this speed are mild. Not to be confused with a solar...

April Flowers for redOrbit.com - Your Universe Online Astrophysicists have debated the outcome of two binary stars – stars that orbit each other – coming together in a "common envelope" for a long time. A new study from the University of Alberta has finally provided some answers. Theoretical astrophysicist Natalia Ivanova has revealed the workings of a celestial event that produces an explosion so powerful its luminosity approaches that of a supernova. “When this dramatic...
