In 1981 the Voyager 2 probe discovered the two faces of Iapetus (see photo), the third largest satellite of Saturn after Titan and Rhea. See also the bulletin of two days ago regarding the Voyager program: https://abod.blog/2023/08/20/august-agosto-20/

Nel 1981 la sonda Voyager 2 scopre le due facce di Giapeto (vedi foto), terzo satellite di Saturno per dimensioni dopo Titano e Rea. Per saperne di più sulla Voyager 2, vedi anche il bollettino dell’altro ieri: https://abod.blog/2023/08/20/august-agosto-20/

@NASA This pair of Voyager 2 images (FDS 11446.21 and 11448.10), two 591-s exposures obtained through the clear filter of the wide angle camera, show the full ring system with the highest sensitivity. Visible in this figure are the bright, narrow N53 and N63 rings, the diffuse N42 ring, and (faintly) the plateau outside of the N53 ring (with its slight brightening near 57,500 km). The original NASA image has been cropped.

In 2008, the NASA Swift satellite in collaboration with the European Space Agency’s XMM-Newton and the International Gamma-Ray Astrophysics Laboratory (INTEGRAL) detected the signal SGR 0501+4516 or “soft gamma repeater“.

Nel 2008 viene rilevato dallo Swift satellite della NASA in collaborazione con l’European Space Agency’s XMM-Newton e International Gamma-Ray Astrophysics Laboratory (INTEGRAL) il segnale SGR 0501+4516 ovvero “soft gamma repeater”.
