Maar het is ze nog nooit gelukt om precies te achterhalen welke ster is geëxplodeerd. Voordat ze in een heldere supernova veranderen, zijn afgelegen sterren meestal te zwak om waar te nemen. Maar sterrenkundigen denken dat ze nu voor het eerst hebben kunnen vaststellen welke ster is geëxplodeerd!

Every year astronomers see dozens of Type Ib supernovae in far away galaxies, but they’ve never managed to identify exactly which star exploded. Before they turn into bright supernovae, the distant stars are usually too faint to make out. However, with this supernova astronomers think that for the first time they've worked out which star created the super-bright object we see in this picture!

Chaque année, les astronomes voient des dizaines de supernovae de Type Ib se produire dans des galaxies lointaines, mais ils n’avaient jamais réussi à identifier précisément quelle étoile avait explosé. Avant de devenir des supernovae très brillantes, ces étoiles lointaines sont souvent trop peu lumineuses pour être visibles.

Cada año los astrónomos observan docenas de supernovas de tipo Ib en galaxias lejanas, pero nunca habían conseguido identificar exactamente qué estrella había explotado. Antes de tornarse en supernovas brillantes, las estrellas lejanas son habitualmente demasiado débiles para detectarlas. Sin embargo, ¡con esta supernova los astrónomos piensan que por primera vez han averiguado qué estrella creó el objeto súperbrillante que vemos en esta fotografía.

Todos os anos os astrónomos observam dúzias de supernovas Tipo Ib em galáxias distantes mas nunca conseguem identificar qual a estrela que explodiu. Antes de se tornar numa brilhante supernova, as estrelas distantes ficam com um brilho tão débil que se torna muito difícil identificá-las. No entanto, neste caso os astrónomos pensam que pela primeira vez conseguiram identificar qual a estrela que criou o objeto super-brilhante que pudemos ver na fotografia.

So, how did they finally manage this? Through a lot of hard work! They scoured hundreds of old photographs showing the region of space the supernova was found in, searching for a star in the exact location of the supernova. And they found one. Even better, it was a massive star that was famous for having super strong winds!
