Summary[edit]

Description
English: This closeup of an image captured by the SOFI instrument on ESO’s New Technology Telescope at the La Silla Observatory shows the free-floating planet CFBDSIR J214947.2-040308.9 in infrared light. This object, which appears as a faint blue dot at the centre of the picture, is the closest such object to the Solar System. It does not orbit a star and hence does not shine by reflected light; the faint glow it emits can only be detected in infrared light. The object appears blueish in this near-infrared view because much of the light at longer infrared wavelengths is absorbed by methane and other molecules in the planet's atmosphere. In visible light the object is so cool that it would only shine dimly with a deep red colour when seen close-up.
Français : Ce gros plan d'une image réalisée par l'instrument SOFI sur le télescope NTT de l'ESO à l'Observatoire de La Silla montre la planète errante CFBDSIR J214947.2-040308.9 dans l'infrarouge. Cet objet, qui apparaît comme un faible point bleu au centre de l'image, est l'objet de ce type le plus proche du Système Solaire. Il ne doit pas être en orbite autour d'une étoile et de ce fait ne peut pas briller par la lumière réfléchie ; la faible lueur qu'il émet ne peut être détectée que dans l'infrarouge. Dans le proche infrarouge, l'objet apparaît bleuâtre car une grande partie de la lumière dans les plus grandes longueurs d'onde infrarouge est absorbée par le méthane et d'autres molécules qui se trouvent dans l'atmosphère de la planète. En lumière visible, cet objet est si froid qu'il ne devrait briller que très faiblement d'une couleur rouge sombre quand on le regarde en gros plan.
