Dark Transit of Jupiter's First Satellite [PDF]
Nature, 1884 ON May 18, at 8h., on observing Jupiter with my 10-inch reflector, p. 252, I saw three very dark spots—one near the planet's centre, and two others not far advanced upon the east limb. These I took to be the shadows of satellites, and on reference found that the shadows of Satellites I. and II. were really upon the planet; also Satellite I. itself. The

Phase transitions and convection in Icy satellites
Geophysical Research Letters, 1986 The effects of solid‐solid phase changes on subsolidus convection in the large icy moons of the outer solar system are considered. Phase transitions affect convection via processes that distort the phase change boundary and/or influence buoyancy through thermal expansion.

CHEOPS: A transit photometry mission for ESA's small mission programme
EPJ Web of Conferences, 2013 Ground based radial velocity (RV) searches continue to discover exoplanets below Neptune mass down to Earth mass. Furthermore, ground based transit searches now reach milli-mag photometric precision and can discover Neptune size planets around bright ...
