This number, known as the Hubble constant, describes the acceleration of the stretching of spacetime.
The best-known is probably the Hubble Space Telescope , which operates at optical frequencies.

Centaurus A is the first galaxy to be studied with the Hubble's infrared camera.
According to Dr Ng, the Hubble observation says nothing about whether time is discrete or continuous.
Finding them in ever-more-distant galaxies was a primary reason for building the Hubble space telescope.
The Hubble's successor, the Next Generation Space Telescope, will also produce vast quantities of new data.
This confirms a hypothesis from the Hubble Space Telescope, which detected signs of ozone around that Moon.

Lockheed Martin built the shroud and support systems for the Hubble, while PerkinElmer and Ball both contributed optics.
He then examined a picture taken by the Hubble space telescope of a galaxy several billion light-years away.
And you can have some telescope time on the Hubble to get to take a better look at this?
P4 was discovered in 2011 in images taken by the Hubble Space Telescope.

Such images will be sharper than those produced by the Hubble, whose mirror is a mere 2.4 metres across.
Since the Hubble Mission is delayed, Space Shuttle Endeavour will be the next to launch before the end of 2008.
The Hubble Deep Field North produced images of thousands of galaxies all within one billion years of the Big Bang.

Dr Cochran's team is hoping to get a firmer result with a longer observing run on the Hubble in August.
Future aperture upper limits on balloon-borne telescopes are expected to be some 2.5-meters, about the size of the Hubble Space Telescope.

For the first time, scientists working at the Hubble Space Telescope were able to directly observe a quasar accretion disc.

Here, just so you can compare, are photos that the Hubble Space Telescope took of the planet Pluto, the outermost planet.
Merlin's images in the radio region of the spectrum are of comparable quality to those of the Hubble Space Telescope observing optically.
For more than two decades now, the Hubble Space Telescope has served up some of the most spectacular astronomical images ever made.

Information on Project Galileo and the Hubble Space Telescope is also available.
In the distant galaxy NGC 5806, astronomers using the Hubble Space Telescope have observed a supernova that happened 80 million years ago.
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.
Beginning today, SETI will open up an online contest to name the moons, both of which were discovered via the Hubble Telescope fairly recently.
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.
