The US version of Life on Mars has been canceled. It will continue to air until the finale in April. According to EW, they gave enough notice to make the finale conclude the series. It managed just one episode more than the UK version (17 eps in one season vs. 16 eps over 2 seasons).
I guess the V remake is real. They announced their first casting today: Scott Wolf.
Space.com has a picture picked by the public as the next target for the Hubble.
