Tycho's Central Peak...

Tycho is a large, relatively young crater on Earth's moon, easily spotted with the naked eye (see photo with red location dot at right).  Tycho has a prominent set of central peaks (as seen in the photo at far right) that can be seen even with binoculars. 

APOD is featuring a photo of those central peaks today, taken a year and a half ago by the Lunar Reconnaissance Orbiter (LRO) – another one of NASA's largely unsung scientific robotic exploration heroes.  Even better, APOD links to this interactive high-resolution photo viewer, which shows the same photo in spectacular 1.5 meter per pixel resolution.  Awesome!
