Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb

A comparison of JunoCam data from April 2024 with imagery from the Galileo mission of the same area in November 1997 (greyscale insert) reveals a new volcanic feature on the surface of Jupiter’s moon, Io.

New Volcano Discovered on Jupiter’s Moon Io in First Close-Up Images in 25 Years

Kobe University researcher Naoyuki Hirata was the first to discover that an asteroid impact on Jupiter's moon Ganymede occurred almost exactly on the meridian farthest from Jupiter. This finding suggested that Ganymede had experienced a reorientation of its rotational axis, enabling Hirata to calculate the type of impact that could have caused this shift.

Ancient Asteroid Impact Shifted Jupiter’s Largest Moon

$Magma ocean planets that contain water – like the earthlike exoplanet GJ 1214 b in this artist’s concept – will only host a tiny fraction of this water on their surface. The majority of it is stored deep in their interiors.$
