[ Watch the Video: What is Jupiter? ] April Flowers for redOrbit.com - Your Universe Online In ancient Rome, Jupiter was the King of the gods and the god of sky and thunder with his mighty thunderbolt. He would certainly be pleased with the changes occurring on his namesake planet. Jupiter the planet is continually being peppered with small space rocks, the atmosphere is changing colors in wide belts, hotspots are vanishing and reappearing, and clouds are gathering and dissipating over...
Singapore, Oct 18, 2012 - (ACN Newswire) - Scientists have identified a mutation in a gene that causes patches of very thick skin to appear on the palms and soles of affected people. This skin disorder is related, albeit in a much milder form, to that of the Indonesian 'Tree Man', Dede Koswara(1). These thick rough skin patches on hands and feet steadily increase in number as a person ages and often coalesce to form larger lesions. In severe cases, these lesions can be painful and...
[Watch the Video: X-ray Satellites Monitor the Clashing Winds of a Colossal Binary] [Watch the Video: Simulation of Colliding Stellar Wind Binary] [Watch the Video: Simulation of Binary Star System] Lee Rannals for redOrbit.com – Your Universe Online Astronomers have X-rayed the stellar winds of two massive stars that are orbiting around one another. Stellar winds can trigger the collapse of surrounding clouds of gas and dust to form new stars, and can also blast the clouds...
[ Watch the Video: Slicing Through View of the Material Around R Sculptoris ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered an unexpected spiral structure in the material around an old star called R Sculptoris The team used the Atacama Large Millimeter/submillimeter Array (ALMA) to discover the surprising spiral structure in the gas around the red giant star, which could mean there is a previously unseen companion star orbiting the star....
NEW ORLEANS, Oct. 10, 2012 /PRNewswire/ -- Building on the success of Round 1, JRL Enterprises announced today a second round of grant opportunities for participation in the "Million Student Study" on math achievement. Grant winners will receive either two I CAN Learn(®) Program school licenses for the price of one, or 40% off a single license.

Lee Rannals for redOrbit.com – Your Universe Online The Milky Way Galaxy is known for its spirals, as well as Earth's home in the cosmos, but now it will also be known as a galaxy that features a halo. Astronomers using NASA's Chandra X-ray Observatory found evidence that the Milky Way Galaxy is embedded in a halo of hot gas that extends for hundreds of thousands of light years. Scientists estimated that the mass of the halo found is comparable to the mass of all the stars in the...
WASHINGTON, Sept. 24, 2012 /PRNewswire-USNewswire/ -- Astronomers have used NASA's Chandra X-ray Observatory to find evidence our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years. The estimated mass of the halo is comparable to the mass of all the stars in the galaxy. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) If the size and mass of this gas halo is confirmed, it also could be an explanation for...

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: --...
