TL;DR: The JUpiter ICy moons Explorer (JUICE) camera system JANUS (Jovis, Amorum ac Natorum Undique Scrutator) will determine the formation and characteristics of magmatic, tectonic and impact features, relate them to surface forming processes, constrain global and regional surface ages, and investigate the processes of erosion and deposition as discussed by the authors.

TL;DR: In this paper , the AO-corrected FoV in the visible domain, with good performance in a 50% sky coverage at the Galactic Pole, is presented, based on the preliminary design of the AOM, which evolved, since the previous phase, as the result of further tradeoffs and optimizations.

TL;DR: In this article, the authors focused their attention on the volume phase holographic grasps (VPHGs) and showed that they can be arranged in a GRISM configuration reaching relative large resolution.

TL;DR: In this paper, the density distribution of real planetary Nebulae and all types of expanding nebulae is studied and a procedure for the determination of the matter radial profile within the sharp portion of nebula in the plane of the sky identified by the zero-velocity-pixel-column (zvpc) of high-resolution spectral images is presented.

TL;DR: The CHEOPS (Characterizing ExOPlanets Satellite) is an ESA Small Mission, planned to be launched in early 2019 and whose main goal is the photometric precise characterization of the radii of exoplanets orbiting bright stars (V < 12) already known to host planets as mentioned in this paper.
