View Full Version : Discussion: Twin Telescopes Peer at Distant ...

SUMMARY: Two linked telescopes at the W.M. Keck Observatory on Hawaii's Mauna Kea took a good look at galaxy NGC 4151 in the infrared spectrum. Located 40 million light years from Earth, NGC 4151 has been well studied by telescopes in various wavelengths, but this is the most detailed infrared image produced. The Keck interferometer works by combining the light from two 10-metre telescopes to create a virtual telescope that's the equivalent of an 85-metre telescope.

We would like to know how far apart two Hubble type telescopes would have to be to create 3-D pictures of our nearest neighboring stars? Especially yellow stars! We would also like to know if its possible for telescopes to distinguish and omit sourse light from polarized light? Thanks for any information you can give.
