However, there are a number of faint, extended and fuzzy objects that were stationary in the night sky: the nebulae. If you were hunting for a new comet and saw one of these nebulae, you might incorrectly identify it for a number of nights, until its stationary nature convinced you it wasn’t a comet after all. Charles Messier was 13 when the great comet of 1744 came close to Earth, and he was both awed and inspired by it. Having spent the next 14 years studying to be an astronomer, he was looking for the soon-tobe-returning Halley’s comet in 1758.

11 Planets like Mars (shown) normally migrate eastwards, ever so slightly, from night-to-night relative to their previous position. This motion is known as prograde or direct motion. Periodically, however, that motion will slow, reverse, slow, and continue in its original direction again, with the period of reverse motion known as retrograde motion. Shown in the figure here is the retrograde motion of Mars relative to the background stars from March to May, 2014. Image credit: E. Siegel, using Stellarium.
