Seeking planets around nearby stars
Article Abstract:
Astronomers have tried to find planets around nearby stars for centuries but have been unable to provide firm evidence of their existence. With the advent of modern equipment, astronomers are actively seeking planets outside our Solar System. Jupiter-like planets should be detectible with modern equipment if they are abundant up to 25 light years from Earth. However, though a space mission would have better detection abilities, one is not going to be approved until ground-based sightings of planets begin.

Article Abstract:
Researchers have mapped the surface of a giant planet outside the Solar System and used the data, which is obtained from NASA's Spitzer Space Telescope, to explore the atmosphere of the planet HD 189733b. They have shown that HD 189733b system is the most favorable planet-star contrast ratio of the known transiting extrasolar planets and is one of the closest systems to Earth.

A theoretical look at the direct detection of giant planets outside the solar system
Article Abstract:
The basic facts of the known members of the extrasolar giant planets (EPGs) family are summarized and a vast majority of EGPs are discovered from the ground using the indirect technique of high-precision stellar spectroscopy. A theoretical analysis is presented to observe the direct detection of giant planets outside the solar system.
