Etymology: Astrophotography is a compound built from two Greek-derived parts, and the older one, "astro-", comes from the Greek "astēr", meaning star. The Greeks also had "astron", a word for a star or a heavenly body, so the star element has been in European languages for a very long time. The second part, "photography", is a much newer coinage: it joins "phōs", the Greek word for light, with "graphō", meaning to write or draw. The result is literally "writing with light" or "drawing with light." The compound is therefore a modern one, put together from ancient parts. "Photography" entered European languages in the nineteenth century, when the technique of fixing images with light was first developed, and "astro-" was attached to it to name the practice of photographing the sky. Nobody in antiquity could have used the word, though the roots behind it are as old as Greek writing itself.
