SPACE-ASTRONOMY-STARS
Picture released 04 October 2006 by the European Space Agency shows one-half of the Hubble Space Telescope field of view with nine stars that are orbited by planets with periods of a few days. Planets so close to their stars with such short orbital periods are called "hot Jupiters. These are considered "candidate" exoplanets - planets that orbit stars other than our own - because most of them are too faint to allow for spectroscopic observations that would allow for a precise measure of the planet’s mass. A seam of stars at the centre of the Milky Way has shown astronomers that an entirely new class of planets closely orbiting distant suns is waiting to be explored, according to a paper published 04 October 2006. An international team of astronomers, using a camera aboard NASA's Hubble telescope, delved into a zone of the Milky Way known as the "galactic bulge", thus called because it is rich in stars and in the gas and dust which go to make up stars and planets. The finding opens up a new area of investigation for space scientists probing extrasolar planets. AFP PHOTO NASA/ESA/K. SAHU (STScI) AND THE SWEEPS SCIENCE TEAM
