Telescopes at the W.M. Keck Observatory.
Oct 2, 2003 NASA satellites have been watching a gigantic iceberg as it disrupts the fragile Antarctic marine environment. The iceberg, named C-19, is 32 km wide and 200 km long; it broke off the Ross Ice Shelf back in May 2002. The problem is that the iceberg stopped winter sea ice from moving out of the Ross Sea region. Phytoplankton, which needs sunlight, was reduced by 90%, and so the rest of the ecosystem suffered too. The iceberg is being watched with NASA's Terra and OrbView2 satellites.
Oct 2, 2003 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.
