Nations vie for giant telescope
"Australia or South Africa will get to host one of the great scientific projects of the 21st Century.
The countries have been shortlisted to be the home of the 1bn-euro-plus Square Kilometre Array (SKA), a giant next-generation radio telescope." http://news.bbc.co.uk/1/hi/sci/tech/5388690.stm CJ

Thanks cjbirch,
It's interesting to see the progress on the SKA project. I'm personally not too picky about where it gets built, as long as it is radio-quiet, and gets built close to on schedule. One of the things they had hoped to do with this project that interested me was to map highly red-shifted 21-cm radiation from the dark age, to show the sequence of proto-galaxy formation from the pre-galactic medium.

Here's hoping. From concept to a fully operational array the process will amass 29 years.
http://www.skatelescope.org/pages/page_timeline.htm I believe there was a thread not too long ago that was asking about proto-galaxy formation, so little is known about this process. CJ

Look here for more details.
The array is being planned for frequencies up to 25-35 GHz. It 30 GHz, we are looking at a wavelength of about 1 cm. With a baseline of 2000 km, the instrument will have a spatial resolution of about a milliarcsecond. At a square kilometer, this array will be about ten times more sensative than the dish at Arecibo. It can be used for any current radio-astronomy project, only faster and more detailed.
