A Jupiter-mass companion to a solar-type star

Article Abstract:

Research on planetary formation has taken on a new turn with the discovery of a satellite to the star 51 Pegasi that showed similar characteristics with those of Jupiter, particularly with regards to mass and density. This specific discovery did not conform to existing theories on extrasolar activity. The object was surmised to be either a gas-giant planet that has changed course or a product of a brown dwarf.

Does low cost mean low-value missions?: Despite an increase in the number of planetary missions, views are mixed about whether NASA's policy of 'better, faster, cheaper' is working

Article Abstract:

The 'leaner' approach to planetary exploration has not convinced all scientists. Large expensive projects like the Cassini launch to Saturn have become politically and economically impossible. The only approved US planetary projects are the Discovery and a line of Mars missions, which do not constitute a fully and balanced programme of exploration, according to scientists.

Giant planet seeks nursery place

Article Abstract:

The 'Doppler wobble', a standard technique that measures the subtle acceleration of host star is used to propose the competing theories of in situ formation of 51 Peg. The results revealed that in orbit around a star that is part of close binary system called HD 188753 another giant planet with a short orbital period is found.
