Canada-France-Hawaii Telescope Legacy Survey Reveals Dark Secrets of the Universe

Astronomers from France and Canada have publicly released the final version of the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS), a unique and powerful multi-color collection of data obtained over 6 years from the summit of Mauna Kea. The imaging project probes an extremely large volume of the Universe, gathering tens of millions of galaxies, some as far as 9 billion light-years away, and provides a treasure trove for many years of astronomical research. This remarkable collection of data is a landmark achievement for CFHT and has inspired observatories around the world. The large number of published results from these images include dark matter maps on the largest scale ever observed and the first high-quality measurements which showed that dark energy closely resembles the cosmological constant that Albert Einstein predicted, but later thought might have been his greatest mistake.
