Description

Description
English: This image, captured by the SPHERE instrument on ESO’s Very Large Telescope, shows the star TYC 8998-760-1 accompanied by two giant exoplanets, TYC 8998-760-1b and TYC 8998-760-1c. This is the first time astronomers have directly observed more than one planet orbiting a star similar to the Sun.

The two planets are visible as two bright dots in the centre (TYC 8998-760-1b) and bottom right (TYC 8998-760-1c) of the frame, noted by arrows. Other bright dots, which are background stars, are visible in the image as well. By taking different images at different times, the team were able to distinguish the planets from the background stars.

The image was captured by blocking the light from the young, Sun-like star (top-left of centre) using a coronagraph, which allows for the fainter planets to be detected. The bright and dark rings we see on the star’s image are optical artefacts.
Italiano: Questa immagine, catturata dallo strumento SPHERE installato su una unità del Very Large Telescope dell'ESO, mostra la stella TYC 8998-760-1 orbitata da due esopianeti giganti, TYC 8998-760-1b e TYC 8998-760-1c. Questa è la prima volta che gli astronomi hanno osservato direttamente più di un pianeta in orbita attorno a una stella simile al Sole. I due pianeti sono visibili come due punti luminosi al centro (TYC 8998-760-1b) e in basso a destra (TYC 8998-760-1c) della cornice, contrassegnati da frecce. Anche altri punti luminosi, che sono stelle sullo sfondo, sono visibili nell'immagine. Scattando immagini diverse in momenti diversi, il team è stato in grado di distinguere i pianeti dalle stelle sullo sfondo. L'immagine è stata catturata bloccando la luce della stella (in alto a sinistra del centro) utilizzando un coronografo, che consente di rilevare i pianeti più deboli. Gli anelli luminosi e scuri che si vedono sull'immagine della stella sono artefatti ottici.
