HOBE SOUND, Fla., Aug. 15, 2012 /PRNewswire-iReach/ -- Any teacher can tell you that instruction, assessment and remediation are inter-connected components of student learning. But if these components are interconnected, why don't teachers use a tool that's interconnected, too?

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have identified the most massive and luminous galaxy cluster ever found, pumping out 740 new stars per year in the central galaxy. The Phoenix cluster was named after the constellation in which it resides, but its more formal name is SPT-CLJ2344-4243. The galaxy cluster sits seven billion light-years away from Earth, and dwarfs most known clusters. Aside from its mass and brightness, Michael McDonald, a Hubble Fellow...
WASHINGTON, Aug. 15, 2012 /PRNewswire-USNewswire/ -- Astronomers have found an extraordinary galaxy cluster, one of the largest objects in the universe, that is breaking several important cosmic records. Observations of the Phoenix cluster with NASA's Chandra X-ray Observatory, the National Science Foundation's South Pole Telescope, and eight other world-class observatories may force astronomers to rethink how these colossal structures and the galaxies that inhabit them evolve....
NEW YORK, Aug. 7, 2012 /PRNewswire/ -- Online review sites may not be anything new, but, for the hospitality business, they are growing more influential all the time. A recent article from a leading hotel industry publication makes note of the concerns that many hotel owners are coming to experience when it comes to consumer review sites. "With online reviews becoming an increasingly important channel for turning browsers into bookers," the article notes, hotel owners are...
Lee Rannals for redOrbit.com - Your Universe Online Japanese researchers using the Faint Object Camera and Spectrograph (FOCAS) on the Subaru Telescope have revealed a clumpy 3D structure of supernovae. The finding supports the clumpy 3D scenario of supernovae explosions, rather than the widely accepted bipolar explosion scenario. The latest research advances the scientific understanding of how supernovae explode, which is a mystery to astronomers. Stars that have reached a mass...
April Flowers for redOrbit.com - Your Universe Online It has long been thought that our Solar System was formed by the shockwave from a supernova explosion. According to this theory, the shockwave also injected material from the exploding star into a cloud of gas and dust. The newly polluted cloud formed the Sun and its surrounding planets. A new study by Alan Boss and Sandra Keiser of the Carnegie Institution for Science, published in The Astrophysical Journal Letters, provides the...
TORONTO, Aug. 1, 2012 /CNW/ - Asian Television Network International Limited (ATN) (TSX-SAT), Canada's largest South Asian Broadcaster, has launched Movies OK, a 24 hour Bollywood Movie Channel from News Corp's STAR Network. ATN is boosting its Hindi cinema-entertainment offerings in Canada with" ATN MOVIES OK", ATNs newest channel that will make movie viewing at home a rewarding experience for families." ATN MOVIES OK" compliments the philosophy of Life OK and caters to the entire...
Lee Rannals for redOrbit.com - Your Universe Online The brightest stars in the universe apparently do not like to live alone, according to a new study using ESO's Very Large Telescope (VLT). Nearly three-quarters of the brightest, high mass stars are found to have a close companion star, which is far more than previous thought. Most of these pairs of stars are also experiencing disruptive interactions, like mass transfer from one star to the other. Another third of them are expected...
[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online In what can be described as a melding of astronomy and post-Impressionist art, one NASA solar scientist has developed a new technique that uses bright, bold colors to share information about the heating and cooling of various parts of the sun. Nicholeen Viall of the NASA Goddard Space Flight Center in Greenbelt, Maryland innovated this new method, which uses various hues splashed across a yellow background...
redOrbit Staff & Wire Reports - Your Universe Online Researchers from a Japanese university have discovered intermediate-mass black hole (IMBH) candidates at the center of the Milky Way, the National Astronomical Observatory of Japan (NAO) announced on Friday. Tomoharu Oka, an Associate Professor at Keio University, and colleagues used radio telescopes to locate four black hole candidates approximately 30,000 light-years from the solar system, located in the direction of the...

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...
UV Astronomy -- UV astronomy is the branch of astronomy and astrophysics which deals with objects visible in ultraviolet (UV) radiation. UV radiation ranges approximatively from 10nm (extreme UV) to 380nm (near UV). Ultraviolet line spectrum measurements are used to discern the chemical composition, densities, and temperatures of interstellar medium, and the temperature and composition of hot young stars. UV observations can also provide essential information about the evolution of...
Hertzsprung-Russell Diagram -- In stellar astronomy, the Hertzsprung-Russell diagram (H-R diagram) shows the relation between the absolute magnitude and the spectral types of stars. It was invented around 1910 by Ejnar Hertzsprung and Henry Norris Russell. There are two equivalent forms. One is the observer's form which plots the color of the star on one axis and the absolute magnitude on the other axis. The theoretician's form plots the temperature of the star on one axis and the...
X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...
Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: --...
