The survey is some 100 times larger than the previous largest map of the web of dark matter, gathered by the Hubble telescope's Cosmic Evolution Survey, or Cosmos.
Such lenses have already been used successfully by the Hubble telescope but, with its longer reach, Subaru ought to be able to employ them to look still further afield.
The tiny satellite it's a mere 8 to 21 miles (13 to 34 km) across showed up as a faint dot on new, long-exposure photos of the Pluto system taken by NASA's Hubble Telescope.

Further news had to wait until astronauts installed the Wide Field Camera 3 on the Hubble telescope in 2009 and again trained it on the candidate, which had - in an SCP tradition of naming supernovae after composers - already been named after jazz musician Charles Mingus.
They've dubbed it a cosmic ghost, and hope to get a better look at it next year when they can get some telescope time on the Hubble Space Telescope.

When combined, the data collected from the dishes will provide a level of detail some 10 times sharper than the Hubble Space Telescope.
Indeed, at some wavelengths it should out-perform the Hubble space telescope, which does not even have the handicap of looking through the atmosphere.
That is four times as much as the Hubble space telescope, a reasonably big piece of science, churned out in its first two decades.
