Big Dipper "Star" Actually a Sextuplet System 88

Posted by kdawson
from the toil-and-trouble dept.
Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

Comment: ATI Driver Issues (Score 4, Interesting) 236

by KJACK98 (#29827563) Attached to: Fedora 12 Beta Released
I've been a loyal fedora user since Fedora 8 when I made the switch to it for my primary OS. I upgraded to Fedora 11 from Fedora 8, and now my system has been constantly becoming unresponsive, even the xconfig changes mentioned on their errata page reduced the freezing but still get it randomly. As for the commercial ATI drivers, they suck and all I get is a black screen with a blinking cursor so I for one am praying they have finally resolved this issue in the next release.

FreeGamer writes "After more than 11 years of development, Flightgear 1.0 has arrived. It was one of the first major Free Software games and has become a flight simulator that rivals it's commercial counterparts. There is an astonishing level of detail to much of the game and yet it can still be played on a modest PC. Flightgear has come of age!"

technosattva (761682) writes "After some time and various release candidates, kernel.org now says:

"The latest stable version of the Linux kernel is: 2.6.23"


While it may take some time for this to trickle down into the various distributions this is exciting news. The new kernel includes various features, such as integration of Xen, and the new scheduling algorithm.

To everyone who has contributed, Thank you!"
