Caméras du SuperWASP sur un châssi OMI

SuperWASP (Wide Angle Search for Planets, « recherche à angle large de planètes ») est un projet de recherche d'exoplanètes par la méthode du transit astronomique. Il vise à couvrir le ciel en entier jusqu'à environ la 15e magnitude.

Il consiste en deux instruments identiques installés sur les sites de deux observatoires : l'Observatoire du Roque de los Muchachos et le South African Astronomical Observatory.
