Lunar Rocks Have Earth's Noble Gases Trapped Inside. More Evidence That the Moon Came From the Earth - by ScottyJ_PhD
Collected in Antarctica , the basalt rock meteorites began life as molten magma within the Moon’s subsurface. It cooled and solidified, before being protected by a second layer of rock on top of it, isolating it from solar winds and radiation. A high-energy event blasted the rock off the Moon, sending it flying towards Antarctica, where it was finally found.

Early models suggested that the giant impact was a moderately slow collision. But recent models offer other options that could produce the same result, including a high energy impact with a fast spinning proto-Earth, which would produce a molten disc of debris and vaporized material, from which the Moon condensed.

Bizarre Underwater Snow Gives Clues About the Icy Shell of Jupiter’s Moon EuropaBelow the thick icy crust of Jupiter's moon Europa is a massive, global ocean where the snow floats upwards onto inverted ice peaks and submerged ravines. Bizarre underwater snow is known to occur below ice shelves on Earth, but new research shows that the same is likely true for Jupiter’s moon. In
