Named Beta Pictoris d, the newly-discovered world is 100 times fainter than Beta Pictoris b -- the first planet discovered around the A5-type star Beta Pictoris -- and is among the lightest exoplanets ever to be imaged from the ground.

Une équipe d’astronomes a découvert par imagerie directe une troisième exoplanète en orbite autour de l’étoile Bêta Pictoris. Baptisée Bêta Pictoris d, elle est 100 fois moins lumineuse que Bêta Pictoris b, la première exoplanète découverte dans ce même système, déjà par imagerie directe. Bêta...

Durante 11 anos esteve ali, praticamente à vista de todos. Entretanto, foi possível perceber que as imagens antigas escondiam um dos exoplanetas mais ténues alguma vez captados diretamente a partir da Terra.

Pela primeira vez, cientistas compararam ambientes magnéticos de outros planetas, um passo fundamental para compreender aqueles que podem ser habitáveis, conservar água e, talvez, um dia, albergar vida tal como a conhecemos - e criar auroras ainda mais espetaculares.
