Two fundamental factors affect all astrophotography—timing and location. If a camera happens to be at the right place at the right time, it can capture images that have never been seen before. And with the proliferation of cameras throughout the solar system, more and more novel photos will be captured at an ever-increasing frequency. China's Tianwen-1 probe added to that novel collection to celebrate its second anniversary by taking a shot of Mars' moon Phobos.

The image itself is stunning, with clear definition of many features of the object, whose length isn't much more than that of Manhattan. Seen in full sunlight, or as we might call it on Earth, as a "full moon," there are some noticeable streaks in the upper left of the photo, which may indicate relatively recent impacts. In addition, a crater named Estonian astronomer Ernst Öpik is visible in the upper right of the image. Other features, named after other astronomers and characters from Gulliver's Travels, aren't as clear on the image, as the space around the Öpik crater is largely featureless.
