04.36: De Gal. maan #Ganymedes staat 0,82'' Z van #Callisto. #Ganymedes bedekt #Callisto voor 29%. De bedekking duurt van 4:31:08 tot 4:40:22 uur. #Jupiter staat i/h oostnoordoosten op een hoogte van 4gr boven de horizon, en goed zicht op de horizon is nodig om dit te kunnen zien. De #Zon staat 21gr onder de horizon en het is goed donker. Om een nauwe samenstand van manen van #Jupiter te bekijken is een goede, stabiele verrekijker op...

Mercury and Jupiter rising in the east in bright morning twilight.
The second image is a magnified view of the first and shows the overexposed disk of Jupiter and faint images of its four Galilean moons: Ganymede, Europa, Callisto, and Io. (Third graphic is from planetarium sky simulation software.)
This is a follow up to my toot from a few days ago:

[#Ganymede and #Callisto: so close and yet so different] They were born in the same environment - the disk of gas and dust surrounding #Jupiter, but differ in their internal structures. What explains this divergence?
The temperatures prevailing within the accretion regions of the two icy moons are thought to be responsible for this differentiation, according to work by researchers at IRAP and @LAM_Marseille.

[#Ganymède et #Callisto : si proches et pourtant si différentes] Elles sont nées dans le même environnement - le disque de gaz et de poussière entourant #Jupiter, mais se distinguent par leurs structures internes. Comment expliquer cette divergence ?
Les températures régnant au sein des régions d'accrétion des deux lunes glacées seraient responsables de cette différentiation, d'après les travaux de chercheurs de l'IRAP et du @LAM_Marseille.
