First result of the SNLS

First result of the SNLS: "WAS EINSTEIN'S BIGGEST BLUNDER A STELLAR SUCCESS? The genius of Albert Einstein, who added a 'cosmological constant' to his equation for the expansion of the universe but later retracted it, may be vindicated by new research. The enigmatic dark energy that drives the accelerating expansion of the universe behaves just like Einstein's famed cosmological constant, according to the Supernova Legacy Survey (SNLS), an international team of researchers in France and Canada that collaborated with large telescope observers at Oxford, Caltech and Berkeley. Their observations reveal that the dark energy behaves like Einstein's cosmological constant to a precision of 10 per cent. 'The significance is huge,' said Professor Ray Carlberg of the Department of Astronomy and Astrophysics at U of T. 'Our observation is at odds with a number of theoretical ideas about the nature of dark energy that predict that it should change as the universe expands, and as far as we can see, it doesn't.' The results will be published in an upcoming issue of the journal Astronomy & Astrophysics."
