The Hubble Telescope will be shortly receiving it's final visitors this month when astronauts return to make repairs and upgrade the telescope.
One upgrade will be on the Wide Field Camera (WFC). The current WFC2 will be replaced with the enhanced WFC3. This state-of-the-art technology is the first imaging platform on Hubble to be able to see images across the ultraviolet and infra-red as well as visible wavebands and will improve the Hubble's sensitivity 10-30 times.
The Hubble site says: “This will give astronomers a unique opportunity to observe the different stellar populations within distant galaxies, study objects at high redshifts and to look for water and ice on bodies within the Solar System.”
Light is directed into the WFC3 using a pickoff mirror. Then the beam is either directed to the UV/Visible channel which features a sensitive CCD camera or to the IR channel.
The new wide-field camera will allow Hubble to take clear and detailed photos over a wide range of colours.
The upgrades will extend the imaging capabilities and the lifetime of the Hubble Telescope.
The Hubble Telescope has had a long and successful existence and in March captured a collections of rare photos of the Saturn Moon transit.
