Moon: July 2020



The unusual dark greenish and glistening "gel-like" substance in a crater on the far side of the moon has attracted widespread interest following its discovery by the Chang'e-4 rover in July 2019.


A research team led by Osaka University investigated the formation ages of 59 lunar craters with a diameter of approximately 20 km using the Terrain Camera (TC) onboard the lunar orbiter spacecraft Kaguya.


The Moon formed a little later than previously assumed.


What started out as a hunt for ice lurking in polar lunar craters turned into an unexpected finding that could help clear some muddy history about the Moon's formation.
