Another Lunar Enigma

Ina (18.66°N, 5.30°E) is one of the most enigmatic landforms on the Moon. First discovered in Apollo-era photographs, then intensely studied with modern observations, its nature is still unknown. The Sun is shining right-to-left, 40...

Hell Q Crater

Recent impact craters are some of the most spectacular landforms on the Moon! For example, Hell Q (3.4 kilometers in diameter, 33.0° S, 355.5° E) shows off pristine impact melt that lined the crater walls and pooled in the bottom, now...

Hawke Crater

Hawke crater, 13.2 km wide, is noticeably tilted because the impactor - an asteroid or a comet - that excavated it struck the sloping inner wall of Grotrian crater. Visible are light-colored rays that attest to the crater's youth, as...

Montes Carpatus

The Montes Carpatus region (16.67°N, 332.93°E) contains numerous examples of volcanic materials. The low albedo (dark) patterns may indicate pyroclastic (explosive) material that erupted over 3 billion years ago. Tobias Mayer G crater...
