<\/p>\n Each of these impact sites stands testament to the violence of its creation \u2014 cataclysmic collisions that carved vast basins in the lunar surface, while hurling debris miles across the face of Earth’s natural satellite. Read on to explore three such geographical wonders named for the legendary astronomers Aristotle, Eudoxus of Cnidus and Giovanni Domenico Cassini, which make for spectacular targets on the nights surrounding the first quarter moon on Jan. 25.<\/p>\n You may like<\/p>\n Eudoxus Crater<\/p>\n Look high above the southern horizon at sunset on Jan. 25 to find the moon with its right half illuminated by direct sunlight and its left veiled in shadow. The 42-mile (67-kilometer) Eudoxus Crater is located in the northeastern quadrant of the lunar surface, above the ancient solidified lava plain of Mare Serenitatis.<\/p>\n The vast impact crater is named for the ancient Greek astronomer and mathematician Eudoxus of Cnidus, who attempted to describe the motion of the planets through the sky by developing a model of our solar system<\/a> in which Earth<\/a> \u2014 at its center \u2014 is surrounded by a series of concentric spheres that dictated the motion of celestial bodies.<\/p>\n \n The Eudoxus and Aristoteles craters on the night of Jan. 25.

A vast swathe of the ancient crater’s eastern interior will be veiled in impenetrable shadow on the night of Jan. 25, giving the impact site a dramatic appearance that is entirely lacking during other lunar phases.<\/p>\n Aristoteles Crater<\/p>\n Next, sweep your eyes just north of Eudoxus to find the 54-mile (87 km) Aristoteles Crater bordering the southern edge of Mare Frigoris (the Sea of Cold). As with Eudoxus, the angle of the moon and sun will cast sections of the Aristoteles Crater into shadow, highlighting the broken terrain bordering its central basin plain, upon which a collection of hill-like features reside.<\/p>\n The crater is named after yet another famous Greek philosopher and astronomer, Aristotle, who lived from 384 to 322 BC. Like Eudoxus, Aristotle believed that Earth was positioned at the center of the universe<\/a> and developed his own model of the solar system in which the sun<\/a>, stars<\/a> and planets revolved around it in a series of solid, crystalline spheres set in motion by a “Prime Mover”, which resided in the outermost sphere.<\/p>\n Aristotle was also among the first of his contemporaries to recognise that Earth was spherical, based on his observations of the curved shadow<\/a> cast on the lunar surface during a lunar eclipse<\/a>.<\/p>\n Cassini Crater<\/p>\n For the final stop of our tour we’ll take a leap towards the terminator, over the Montes Caucasus mountain range to visit the Cassini Crater, which can be found scarring the eastern edge of Mare Imbrium (the Sea of Showers) 40 degrees above the lunar equator.<\/p>\n You may like<\/p>\n \n The Eudoxus and Aristoteles craters on the night of Jan. 25. (Image credit: NASA Scientific Visualization Studio, edited by Anthony Wood in Canva)<\/p>\n The 35-mile (57 km) wide impact site was named after the 17th\/18th century astronomer Jean-Dominique Cassini. His illustrious career saw him make detailed observations of the planets, calculate the rotational speed of Mars<\/a> and discover the Saturnian moons Rhea<\/a>, Tethys<\/a> and Dione<\/a>.<\/p>\n Only the outer rim of the Cassini Crater is visible, with the basin itself having been flooded by molten lava, which cooled many millions of years ago to resurface its interior. Two younger craters have since formed within Cassini’s expanse, the basins of which are drenched in darkness around the time of the first quarter moon, making for a visually spectacular telescopic target.<\/p>\n Want to explore the moon’s ancient surface for yourself?
