WASHINGTON, April 4, 2013 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago. (Logo - http://photos.prnewswire.com/prnh/20081007/38461LOGO) SN Wilson belongs to a special class called Type Ia supernovae. These bright beacons are prized by astronomers because they provide a...
ESA/Hubble The NASA/ESA Hubble Space Telescope has broken the record in the quest to find the furthest supernova of the type used to measure cosmic distances. This supernova exploded more than 10 billion years ago (redshift 1.914), at a time the Universe was in its early formative years and stars were being born at a rapid rate. The supernova, designated SN UDS10Wil, belongs to a special class of exploding stars known as Type Ia supernovae. These bright beacons are prized by astronomers...
All-optical switching promises terahertz-speed hard drive and RAM memory Researchers at the U.S. Department of Energy’s Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used in magnetic memory technologies. Magnetic switching is used to encode information in hard drives, magnetic random access memory and other computing devices. The discovery, reported in the April 4...

[ Watch the Video: AMS Time Lapse Installation ] John P. Millis, Ph.D. for redOrbit.com – Your Universe Online For decades scientists have wondered whether a mysterious form of matter – known simply as Dark Matter since it does not interact directly with light – makes up the majority of the “stuff” in the Universe. Researchers have pointed to the seminal work on the Bullet Cluster of galaxies as evidence that dark matter is a real substance. But similar observations of...
John P. Millis, Ph.D. for redOrbit.com – Your Universe Online Nobel Laureate Richard Feynman once declared that turbulence is “the most important unsolved problem in classical physics.” The phenomenon of turbulence is quite common, apparent in the flow of air in our atmosphere, or the rise of smoke from a cigarette. Yet, a mathematical description of turbulence has continued to escape scientists, despite having been studied for hundreds of years. In 1941 Soviet mathematician...
In recognition of National Stress Awareness Month, The Oxygen Plan Corporation makes online stress test available for all to learn their Stress Number®. Minneapolis, Minnesota (PRWEB) April 03, 2013 As many scramble to meet the deadline for filing the 2012 income tax returns, acute stress may be rising with it. According Dr. Donald E. Williams, board-certified clinical health psychologist (American Board of Professional Psychology/ABPP), and Chief Science Officer, The Oxygen Plan,...
Lee Rannals for redOrbit.com – Your Universe Online MIT researchers writing in the journal Proceedings of the Royal Society A say they found ionic wind thrusters may be a more efficient source of propulsion than conventional jet engines. Ionic wind, or electrohydrodynamic thrust, was first identified in the 1960s. The phenomenon takes place when a current passes between two electrodes, creating a wind in the air between. If enough voltage is applied, the wind produces a thrust...

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...
Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...
Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...
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...
