Latest Star Stories
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...

Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Agency (ESA) shows multiple arcs around Betelgeuse, the nearest red supergiant star to Earth. Betelgeuse and its arc-shaped shields could be colliding with a dusty "wall" in the next 5,000 years, according to ESA. The red supergiant star sits at the constellation Orion the Hunter, and can easily be seen with the naked eye in the northern hemisphere winter night sky as an orange-red star to...

[Watch Videos: 1 - Zooming in on Lupus 3 / 2 - Panning Over Lupus 3] Lawrence LeBlond for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) released a stunning new image of a dark cloud where new stars are forming, along with a cluster of brilliant stars that have already emerged from the stellar nursery. The new image, taken with MPG/ESO 2.2-meter telescope at La Silla Observatory in Chile, is one of the finest and clearest ever taken in visible light of...
April Flowers for redOrbit.com - Your Universe Online A multinational team of scientists has revealed new information about the explosive events known as novae. Novae are dramatic stellar explosions driven by nuclear processes that make previously unseen stars visible for a short time. The team of astrophysicists measured the nuclear structure of the radioactive neon produced through this process in unprecedented detail. The study, led by the University of York, UK, and Universitat...
FOREST, Va., Jan. 14, 2013 /PRNewswire/ -- When a hotel offers something truly unique to first-time and repeat guests, word spreads quickly. When that offering helps keep germs from spreading, word-of-mouth goes viral in a good way. That's what happened at the boutique Craddock Terry Hotel in Lynchburg, Virginia, when they started featuring a trio of NanoTouch(TM) products in their guest rooms. As the world's first manufacturer of printed, portable, removable, and self-cleaning...
redOrbit Staff & Wire Reports – Your Universe Online An unusually dense cloud located near the center of the galaxy does not appear to be forming any massive stars, astronomers at the California Institute of Technology (Caltech) have discovered, and that behavior has them puzzled as it appears to defy the rules of star formation. The cloud, which the researchers have named G0.253+0.016, is located in the vicinity of a supermassive black hole three millions times as massive as the...
April Flowers for redOrbit.com -- Your Universe Online Astronomers announced this week that a massive star they have been watching repeatedly mimic a supernova since 2009 has finally exploded for real. The team, led by the University of Arizona, presented their findings to the American Astronomical Society meeting and they will be published in the Monthly Notices of the Royal Astronomical Society. This new study provides critical information on the final death throes of massive stars in...

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: --...
