More details on the distance, size, and resolution for the individual images are provided in the captions below. While most of #Rosetta’s NAVCAM images are taken for navigation purposes, these images were obtained to provide context in support of observations performed at the same time with the Alice ultraviolet (UV) imaging spectrograph on Rosetta. Alice makes its observations through a narrow, long slit (you can read about Alice’s first far-UV spectra and find an animation showing the size and shape of its field of view in an earlier blog post), and scientists use NAVCAM images taken at the same (...)
