English: This picture shows the sky around multiple star Gliese 667. The bright star at the centre is Gliese 667 A and B, the two main components of the system, which cannot be separated in this image. Gliese 667C, the third component, is visible as a bright star, very close and just under A and B, still in the glare of these brighter stars. The very subtle wobbles of Gliese 667C, measured with high precision spectrographs including HARPS, revealed it is surrounded by a full planetary system, with up to seven planets.
Note that this image was assembled from two photographic plates taken years apart through different coloured filters. During that time, the motion of the nearby stars Gliese 667AB and C was sufficient for them to appear doubled in this picture, with one red and one blue image of each star.
This picture also shows two regions of star formation, much further from Earth than Gliese 667. At the upper-left NGC 6357 is visible and towards the bottom of the picture NGC 6334 (The Cat’s Paw Nebula).
Français : Cette image montre le ciel autour de l'étoile multiple Gliese 667. L'étoile brillante au centre est Gliese 667 A et B, les deux composantes principales du système, qui ne peuvent être différenciées dans cette image. 667 C, le troisième élement, est visible comme une étoile brillante, particulièrement proche et juste sous A et B, dans l'éclat de ces corps lumineux. Les subtiles oscillations de Gliese 667 C, mesurées avec des spectrographes de haute précision, dont HARPS, ont révélé qu'elle est entourée d'une système planètaire complet, avec jusqu'à 7 planètes distinctes.
Notez que cette image est la réunion de deux photographies prises à plusieurs années d'intervalles avec différents filtres colorés. Cet intervalle est suffisant pour que le mouvement des étoiles Gliese 667 A, B et C soit notable, entraînant leur doublement sur cette image, une en rouge et l'autre en bleu.
Cette image montre également deux régions de formation d'étoiles, bien plus distantes de la Terre que de Gliese 667. En haut à gauche est visible NGC 6537 et vers le bas de l'image, NGC 6334 (Nébuleuse de la Patte de Chat).
