Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Mare Frigoris." Dubbed 'Sea of Cold' by Giovanni Riccioli in 1651, Mare Frigoris is located near the lunar North Pole. Oriented above the dark-floored crater Plato just left of center in this image, Mare Frigoris is lighter in color than nearby Mare Imbrium ('Sea of Rains', just below Plato and extending back to the left). Here's where the geology gets interesting. The material in Mare Frigoris is thought to be 1-3 billion years old. The material in Mare Imbrium is estimated to be only 3 million years old. Why? Scientists believe that Mare Imbrium is actually an impact crater produced by a ~25 km-sized proto-planet. The floor of the crater was flooded by lava upon impact, which cooled to produce the 'sea' surface we now view from Earth.

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) is titled "Mare Frigoris." Dubbed 'Sea of Cold'

APOD background
"Explanation: Lighter than typically dark, smooth, mare the Mare Frigoris lies in the far lunar north. Also known as the Sea of Cold, it stretches across the familiar lunar nearside in this close up of the waxing gibbous Moon's north polar region. Dark-floored, 95 kilometer wide crater Plato is just left of the center. Sunlit peaks of the lunar Alps (Montes Alpes) are highlighted below and right of Plato, between the more southern Mare Imbrium (Sea of Rains) and Mare Frigoris. The prominent straight feature cutting through the mountains is the lunar Alpine Valley (Vallis Alpes). Joining the Mare Imbrium and Mare Frigoris, the lunar valley is about 160 kilometers long and up to 10 kilometers wide."
