A team of astronomers using ESO's Very Large Telescope has imaged a faint object moving near a bright star. With an estimated mass of four to five times that of Jupiter, it would be the least massive planet to be directly observed outside the Solar System. The discovery is an important contribution to our understanding of the formation and evolution of planetary systems.
Although nearly a thousand exoplanets have been detected indirectly - most using the radial velocity or transit methods [1] - and many more candidates await confirmation, only a dozen exoplanets have been directly imaged.
