'These detections indicate that low-mass planets are quite common around nearby stars. The discovery of potentially habitable nearby worlds may be just a few years away,' said Steven Vogt, a professor of astronomy and astrophysics at UCSC. Among hundreds of our nearest stellar neighbors, 61 Vir stands out as being the most nearly similar to the Sun in terms of age, mass, and other essential properties."

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."

Last month we discussed news that Microsoft had banned hundreds of thousands of Xbox users for using modified consoles. The Electronic Frontier Foundation has now pointed to this round of bans as a prime example of the power given to providers of online services through 'Terms of Service' and other usage agreements. "No matter how much we rely on them to get on with our everyday lives, access to online services — like email, social networking sites, and (wait for it) online gaming — can never be guaranteed. ... he who writes the TOS makes the rules, and when it comes to enforcing them, the service provider often behaves as though it is also the judge, jury and executioner. ... While the mass ban provides a useful illustration of their danger, these terms can be found in nearly all TOS agreements for all kinds of services. There have been virtually no legal challenges to these kinds of arbitrary termination clauses, but we imagine this will be a growth area for lawyers."
