Cover image: ESO PR Photo 14a/05. The first planet outside of our solar system to be imaged orbits a brown dwarf (centre-right) at a distance that is nearly twice as far as Neptune is from the sun. 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. © ESO.
