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.
Sometimes they need a little help from something like the Hubble Space Telescope, but its our peepers that ultimately spotted Pluto's fifth moon, P5.

Next, we will be told that the Secretary of State is going to be performing brain surgery or correcting the flaws in the Hubble Space Telescope.
CENTERFORSECURITYPOLICY: Flash: Secretary Baker To Perform Brain Surgery
The transit of Venus can't be observed with the Hubble Space Telescope because the extreme brightness of the sun would destroy the telescope and its instruments.
He joined Nasa in 1980 and is a veteran of four space shuttle flights, commanding the mission that launched the Hubble Space Telescope into orbit in 1990.
On 3 November, NASA and the European Space Agency announced that the Hubble Space Telescope had captured the first visible-light snapshot of a planet orbiting another star.
Follow-up observations are also being planned using other ground-based instruments, as well as several space observatories, including the Hubble Space Telescope and the infrared Spitzer Space Telescope.

Just a fortnight ago, astronomers using the Hubble space telescope identified water vapour in the atmosphere of an exoplanet, albeit a gaseous exoplanet some 150 light years away.
At its best, RadioAstron will be able to resolve points separated by an angle of just 7 microarcseconds, about 10, 000 times the resolution of the Hubble Space Telescope.
Notable highlights in the ship's career have included the first construction mission to the ISS by a US orbiter, and the first servicing mission to the Hubble Space Telescope.

Astronomers using the Hubble Space Telescope have discovered a supernova in the distant galaxy NGC 5806, which is a relatively unremarkable galaxy located about 80 million light years from Earth.
Riess and colleagues used the Hubble Space Telescope to measure supernovae that are very far away, showing that dark energy must be responsible for how the universe appears to expand faster and faster.
The Hubble Space Telescope recently spied a cluster of young blue stars surrounding a rare mid-weight black hole that suggests the black hole was once at the center of a dwarf galaxy.
Formally called SN SCP-0401, the supernova was something of a chance find in a survey carried out in part by the Supernova Cosmology Project (SCP) using the Hubble space telescope, first undertaken in 2004.
