An international team of astronomers has discovered eight new extrasolar planets, bringing to nearly 80 the number of planets found orbiting nearby stars.
Scientists are mystified by what may be unexpected, wandering, planet-sized objects. A new image taken by NASA's Hubble Space Telescope implies the presence of these objects.
Proving that two telescopes are better than one, NASA astronomers have gathered the first starlight obtained by linking two Hawaiian 10-meter (33-foot) telescopes. This successful test at the W.M. Keck Observatory on Mauna Kea makes the linked telescopes, which together are called the Keck Interferometer, the world's most powerful optical telescope
system.
