Brett Smith for redOrbit.com - Your Universe Online Researchers searching for planets orbiting around a distant star look for a signature dimming of that star’s light, but what if the distant star suddenly gets a bit brighter? Astronomers from the University of Washington observed just such a phenomenon, but instead of concluding they had found an ‘upside-down’ planet, the scientists realized they had found a new way to study binary star systems, according to their report...

Astronomers at the University of Warwick and the University of Sheffield have helped discover an unusual star system which looks like, and may even once have behaved like, a game of snooker. The University of Warwick and Sheffield astronomers played a key role in an international team that used two decades of observations from many telescopes around the world. The UK astronomers helped discover this "snooker like" star system through observations and analysis of data from an astronomical...

A team of Chinese astronomers have discovered a giant planet close to the exotic binary star system QS Virginis. Although dormant now, in the future the two stars will one day erupt in a violent nova outburst. Professor Shengbang Qian of Yunnan Observatory leads the team of scientists who report their work in the journal Monthly Notices of the Royal Astronomical Society. QS Virginis lies in the direction of the constellation of Virgo and is about 157 light years from the Sun. The system is...

Project 1640 sees the unknown using a novel technique known to Galileo Next time you spy the Big Dipper, keep in mind that there is another star, invisible to the unaided eye, contributing to this constellation. According to a new paper published in The Astrophysical Journal, one of the stars that makes the bend in the ladle's handle, Alcor, has a smaller red dwarf companion. Newly discovered Alcor B orbits its larger sibling and was caught in the act with an innovative technique called...

Twentieth Century Fox makes history by transmitting the first motion picture in to deep space, making THE DAY THE EARTH STOOD STILL the world's first galactic motion picture release. The first deliberate deep space transmission of this highly anticipated science fiction thriller will begin this Friday, December 12, 2008, to coincide with the film's opening day on Planet Earth. If any civilizations are currently orbiting Alpha Centauri, they will be able to receive and view the film...

AUSTIN, Texas — A quartet of stars has been discovered in an intimate cosmic dance, swirling around each other within a region about the same as Jupiter's orbit around the sun. Astronomers say a gaseous disk might have once engulfed and pushed the stars into their tight orbits. Though bright, the stellar system was thought to be a single star dubbed BD -22°5866. Now, research presented here today at a meeting of the American Astronomical Society reveals the pinpoint of...

NASA -- We tend to think of the North Star, Polaris, as a steady, solitary point of light that guided sailors in ages past. But there is more to the North Star than meets the eye. The North Star is actually a triple star system. And while one companion can be seen easily through small telescopes, the other hugs Polaris so tightly that it has never been seen "“ until now. By stretching the capabilities of NASA's Hubble Space Telescope to the limit, astronomers have photographed the...

NASA -- A scientist using NASA's Chandra X-ray Observatory has found evidence that two white dwarf stars are orbiting each other in a death grip, destined to merge. The data indicate gravitational waves are carrying energy away from the star system at a prodigious rate, making it a prime candidate for future missions designed to directly detect these ripples in space-time. Einstein's General Theory of Relativity predicted a binary star system should emit gravitational waves that rush away...

Triple Star -- A triple star system consists of three gravitationally bound stars. The stars are in orbits around a common center of mass, usually so that two of the stars form a close binary star and the third is further away. This configuration is often called a hierarchical triple star. Multiple stars containing more than three stars can usually be decomposed to binaries and single stars that are in a hierachically bound system. ----- Click here to learn more on this...

Double Star -- When two stars are so nearly in the same direction as seen from Earth that they appear to be a single star to the naked eye but may be separated by the use of telescopes, they are referred to as a double star. There are two different kinds of double star. In the case where two stars are only apparently close to each other, but which are in fact separated by a great distance are known as optical doubles or optical binaries. In the vast majority of cases, however, the two...

Binary Star -- A binary star system consists of two stars both orbiting around a gravitational point between them. The term "binary star" was apparently first coined by Sir William Herschel in 1802 to designate "a real double star - the union of two stars that are formed together in one system by the laws of attraction." At present, binary stars are classified into three types according to their observable properties: visual binaries, spectroscopic binaries, and eclipsing binaries....

Proxima Centauri -- The red dwarf star Proxima Centauri (also Alpha Centauri C), part of the Alpha Centauri star system, is the nearest star to our Earth other than the Sun. Proxima Centauri is roughly 4.22 light years from Earth, 270,000 times as far as the sun. Its apparent magnitude is 11 (very weak, as red dwarfs in general are: far too weak to be observable with the naked eye). Proxima Centauri has often been suggested as a logical first destination for interstellar travel....

Alpha Centauri -- Alpha Centauri is the brightest star system in the southern constellation of Centaurus, and is the third brightest in the entire night sky (although too far south to be visible in most of the northern hemisphere). It is also the closest star system to Earth. It bears the proper name Rigil Kentaurus (often shortened to Rigil Kent), meaning "foot of the centaur" in Arabic, but is nonetheless usually referred to by its Bayer designation Alpha Centauri. Alpha Centauri is...

'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
