Solar Twin Revealed By CoRoT

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Our knowledge of how stars evolve arises out of our survey of billions of stars within and outside of our galaxy. As we piece together the snapshots of these stars of various sizes and masses, at various stages of their evolution, we begin to get a complete picture of how stars are born, live, and die. Of course, stars most similar to our Sun are perhaps the most relevant as they can tell us about our Sun´s past...

Sun Produces An X1.7 Solar Flare, Followed By An X2.8
2013-05-13 12:04:28

Lawrence LeBlond for redOrbit.com - Your Universe Online On Sunday (May 12) the Sun emitted a significant solar flare that is being classified as the first X-class event of 2013. The X1.7 flare, which peaked at about 10 p.m. EDT, was also associated with another solar event known as a coronal mass ejection (CME). While CMEs can release radiation and solar material in the direction they were produced, Sunday´s phenomenon was not directed at Earth. While solar flares also have the...

Will Adding the Best Possible UV-free Tanning equipment to an already stacked set of top rated UV-beds make Always Tan in Lubbock a contender for best salon in the country? Lubbock, Texas (PRWEB) April 18, 2013 Can it be true? Sunless Tanning machines that don´t turn your skin orange like the Oompa Loompas from the old Willy Wonka movie? Is it really possible to have multiple UV-free Tanning options inside of a really stylish building where top-of-the-line machines and Best of the...

Most Massive Binary Candidate Identified
2013-04-17 04:52:37

April Flowers for redOrbit.com - Your Universe Online A team of astronomers, led by Hugues Sana of the University of Amsterdam, has observed a binary star that potentially weighed 300 to 400 times the mass of our Sun at its birth. The present day combined mass of the two stars is between 200 and 300 times the solar mass, depending on its evolutionary stage. This makes it potentially the most massive binary star discovered to date. The findings of this study have been published in...

Kappa Coronae Borealis
2013-04-10 05:00:44

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Herschel space observatory has snapped images of a dust belt orbiting a subgiant star that hosts a planetary system. The space observatory's sensitive far-infrared detection helped astronomers resolve bright emission around Kappa Coronae Borealis, indicating the presence of a dusty debris disc. The star is a little heavier than our own Sun at 1.5 solar masses, is around 2.5 billion years old, and sits...

Alpha Centauri B May Shed Light On Our Own Sun’s Anomalies
2013-02-20 12:52:10

Michael Harper for redOrbit.com — Your Universe Online As it turns out, studying our Sun can be rather difficult. It´s not the distance so much that keeps scientists guessing — although that certainly doesn´t help. The Sun´s intense heat also keeps scientists at bay, leaving them to make some of their observations and predictions based purely on context and far away measurements. One thing astronomers have been able to observe is a significant difference in...

Stellar Evolution -- Stellar evolution is the process of formation, life, and death of stars. It is one of the major topics of cosmogony. Star Birth and Life A star starts out as an enormous cloud of gas and dust many light-years across. Star formation begins when the cloud begins to condense under its own gravity. The processes that initiate this contraction are not fully understood. The cloud fragments fuse into stellar mass clouds known as protostars. Protostars do not emit...

Solar System
2012-10-22 06:09:41

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...

Solar Eclipse -- A solar eclipse occurs when Sun, Moon and Earth are on a single line, the Moon being in the middle. Seen from the Earth, the Moon is in front of the Sun and thus part or all of the light of the Sun is hidden by the Moon. Thus it may seem that a piece has been taken out of the Sun, or that it has suddenly disappeared. There are three types of solar eclipses: -- A partial solar eclipse: Only part of the Sun and the Moon overlap -- A total solar eclipse: All of the Sun...

The Sun -- intensely hot, self-luminous body of gases at the center of the solar system. Its gravitational attraction maintains the planets, comets, and other bodies of the solar system in their orbits. The sun is actually a star of about medium size; it appears larger than the other stars because of its relative nearness to the earth. The earth's distance from the sun varies from 91,377,000 mi (147,053,000 km) at perihelion to 94,537,000 mi (152,138,000 km) at aphelion (see apsis). The...

Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....
