keenly & closely: Mars, photographed by Hubble Space Telescope, winter 2003.
Lighter northern plains on the left; darker southern highlands and south polar cap at right. The Hellas Basin is a lighter area at top right, and the Argyre Basin at bottom right, on the edge of night.
From Proposal 9975.

morning when dawn’s left hand was in the sky: Surface of Mercury, photographed by MESSENGER, 10th February 2012.
If I’m interpreting landmarks correctly, we are looking up at the south pole here. At the top of the image is sunrise along 70°W longitude, and at the bottom is sunset at along 250°W.
Composite of two images. I collected quite a few of these shots in the hope of making a rotating-Mercury-timelapse gif, but as yet I haven’t had any luck with that.

female creatures: Surface of Mars, photographed by Mars Reconnaissance Orbiter, 9th Juny 2007.
“Gullies in Gorgonum Chaos mesas” around 37°S 190°E in the northwestern Terra Sirenum.
The chaos and terra are named for the Gorgon and Sirens of Greek mythology; both, interestingly, are female and extremely dangerous, perhaps mythic expressions of male insecurities.

trails: Ship tracks in the Pacific, photographed by Aqua, 15th January 2013.
About 1,100km due west of the coast of Oregon. Perhaps the prettiest type of pollution, ship tracks are clouds seeded by ship exhausts.

hunter: Surface of the Moon, photographed from Apollo 15, 2nd August 1971.
Around 25°S 120°E. Zhiritskiy Crater is at center left, overlapping the more central crater. Part of Neujmin is visible at right, and a tiny bit of Schaeberle peeps in at bottom left. Named, respectively, for rocket scientist Georgiy Sergeevich Zhiritskiy, 1893-1966; astronomer Grigory Nikolayevich Neujmin, 1886-1946; astronomer John Martin Schaeberle, 1853-1924.
