SNAP
Informació general
Tipus	observatori espacial
	Operador NASA

L'SNAP és un telescopi en òrbita del Projecte Supernoves i Cosmologia. Sonda de les Supernoves i l'Acceleració, creat com a iniciativa conjunta de la NASA i el Departament d'Energia dels Estats Units.^[1] El telescopi SNAP tindrà una càmera òptica d'1 grau quadrat de camp de visió, i una petita càmera en l'infraroig proper. Un espectrògraf podrà descompondre la llum de les supernoves des del seu color ultraviolat proper fins a l'infraroig proper. Un dels objectius d'SNAP és usar les supernoves de tipus Ia com a marcadors de l'expansió de l'univers, i analitzar com l'energia fosca ajuda a frenar el creixement de les galàxies.^[2]

Since then, other tools have emerged by which astronomers can also gauge dark energy by how it retards the growth of galaxies and other structures in the universe. Way back in 1999, Saul Perlmutter of the Lawrence Berkeley Laboratory, one of dark energy’s discoverers, proposed a space mission known as SNAP (Supernova Acceleration Probe) to do just that.»
