The Mysterious Stranger (Wikipedia) The Mysterious Stranger is a novel attempted by the American author Mark Twain. He worked on it intermittently from 1897 through 1908. Twain wrote multiple versions of the story; each involves a supernatural character called “Satan” or “No. 44”. All the versions remained unfinished (with the exception of the last one, No. 44, the Mysterious Stranger).

Andromeda (constellation) (Wikipedia) Andromeda is one of the 48 constellations listed by the 2nd-century Greco-Roman astronomer Ptolemy, and one of the 88 modern constellations. Located in the northern celestial hemisphere, it is named for Andromeda, daughter of Cassiopeia, in the Greek myth, who was chained to a rock to be eaten by the sea monster Cetus. Andromeda is most prominent during autumn evenings in the Northern Hemisphere, along with several other constellations named for characters in the Perseus myth. Because of its northern declination, Andromeda is visible only north of 40° south latitude; for observers farther south, it lies below the horizon. It is one of the largest constellations, with an area of 722 square degrees. This is over 1,400 times the size of the full moon, 55% of the size of the largest constellation, Hydra, and over 10 times the size of the smallest constellation, Crux.
Northern celestial hemisphere (Wikipedia) The northern celestial hemisphere, also called the Northern Sky, is the northern half of the celestial sphere; that is, it lies north of the celestial equator. This arbitrary sphere appears to rotate westward around a polar axis due to Earth’s rotation.
