The cover shows carrot spacecraft piloted by rabbits.
Link between the picture and the science contained in the paper: Umbelliferone a coumarin fluorophore was used to prepare the sensor employed in this project and is found in carrots. When our sensor reacts with the nitoreductase (NTR) enzyme it releases the fluorescent blue umbelliferone molecule. Nitroreductase (NTR), is one of a series of biomarkers that have been shown to be significantly upregulated in cells under hypoxic stress. Hypoxia is a condition where cells are deprived of adequate oxygen.
Therefore the picture is set in space with the moon representing a cell under hypoxic stress. Therefore, the carrot spacecraft burrowing into the moon change from orange to blue representing the release of the fluorescent blue umbelliferone under hypoxic conditions. The Earth has normal oxygen levels and so no carrot spacecraft have targeted the earth. Importantly, even if they had targeted and burrowed into the Earth they would have remained orange due to the normal oxygen levels.
