Eridanus, the river, flows into the evening sky this month. This long, winding trail of stars begins to rise around 8 or 9 p.m., but it is so long that its easternmost stars don’t clear the horizon until about midnight.

October 28: Eridanus
October 29: Venus and Saturn
Two planets are slipping past each other in the early evening sky. Venus is the “evening star.” The fainter planet Saturn stands to the upper right of Venus this evening, and a bit farther from it on succeeding nights.
October 30: New Moon
The Moon is new today at 12:38 p.m. CDT as it crosses the line between Earth and Sun. Our satellite world is lost in the Sun’s glare, but will return to view as a thin crescent shortly after sunset tomorrow or the next day.
October 31: Algol
Four stars in Perseus represent the Gorgons, the mythological sisters whose heads were covered with snakes. For a couple of hours every three days, the brightest of them, Algol, fades dramatically as one member of the binary system covers the other.
