Photographed in 2004 using adaptive optics in the near infrared, 2M1207 b is 100 times fainter than its companion brown dwarf. Spectral analysis indicates that the object is similar to a brown dwarf, and it's brightness indicates low mass, both of which would be indicative of a young giant planet. Given the spectral analysis, it is unlikely this is a background star or galaxy, although it is possible that the object is a more massive background brown dwarf. Further observations will be needed of this object's motion relative to 2M1207 over the next few years to determine if it really is an orbiting planet.

First Photograph of an Exoplanet

2M1207-image A composite image of the brown dwarf object 2M1207 (center) and the fainter object seen near it, at an angular distance of 778 milliarcsec. Designated a "Giant Planet Candidate Companion" by the discoverers, it may represent the first image of an exoplanet. Further observations, in particular of its motion in the sky relative to 2M1207 are needed to ascertain its true nature. The photo is based on three near-infrared exposures (in the H, K and L' wavebands) with the NACO adaptive-optics facility at the 8.2-m VLT Yepun telescope at the ESO Paranal Observatory
