Seeing & Understanding
image by George Tarsoudis, Greece
I try to learn something from each lunar image. Often it pops right out, because the lighting reveals a feature in a different perspective than I've noticed it before. In George's spectacular Tycho image I see two features freshly, and one new understanding emerges. If you look beyond Tycho's impact melt-covered floor, beyond the rim, the beginning of its odd crater chain is visible at top center. This secondary crater chain extends two to three times further outside this image. It is unusual because it so close to Tycho - most secondary chains start further away from their primaries, its craters don't look like normal secondary craters, and it is decidedly non-radial! A second newly appreciated feature occurs near bottom left. A small crater, partially within another rim, is on the floor of Chuck Wood
