The discovery was made possible through cooperation between two international research teams -- Microlensing Observations in Astrophysics, or MOA, and Optical Gravitational Lensing Experiment, or OGLE. The newly discovered star-planet system is 17,000 light years away, in the constellation Sagittarius. The planet, orbiting a red dwarf parent star, is most likely one-and-a-half times bigger than Jupiter. The planet and star are three times farther apart than Earth and the Sun.Together, they magnify a farther, background star some 24,000 light years away, near the Milky Way center.

Object Type: Jovian Parent Star: 2003-BLG-235 Discovery Status: Strong Microlensing Candidate Mass : 1.5 Jupiters Mean Distance: 3 AU Year Discovered: 2004 Detection Method: Transit, confirmed by Doppler Spectroscopy Discovered By: I. Bond et al The detection of an extrasolar planet by means of microlensing is certainly a cause for celebration in planet hunting circles. The technique was first proposed by Dr. Boghdan Paczynski of Princeton University in 1991, but all previous claims of a successful detection have proved inconclusive. "I am thrilled to see the prediction come true with this first definite planet detection through gravitational microlensing" said Paczynski, now a member of the OGLE team.
