Lancement du télescope spatial Nancy Grace Roman: «On va pouvoir mieux comprendre l'évolution de l'univers»

Le télescope Nancy Grace Roman a décollé il y a une heure depuis le centre spatial de Cap Canaveral en Floride. Il doit maintenant parcourir 1 million et demi de kilomètres. Une mission spatiale de cinq ans minimum pour découvrir des milliers d'exoplanètes et des dizaines de milliers de supernovas. Les astronomes s'attendent à des images spectaculaires car ce télescope est le plus ambitieux depuis le lancement de James Webb en 2021 : son champ de vision est cent fois plus large que celui du télescope Hubble. Pour en parler, RFI reçoit Éric Lagadec, enseignant-chercheur, astronome adjoint au sein du laboratoire Lagrange de l’observatoire de la Côte d'Azur.
