5. The Night Sky Friday, January 11 · In early evening at this time of year, the Great Square of Pegasus balances on one corner high in the west. The vast Andromeda- Pegasus constellation complex runs all the way from near the zenith (Andromeda's foot) down through the Great Square (Pegasus's body) to low in the west (Pegasus's nose). Saturday, January 12 · As twilight turns to night, look low in the northwest for Vega. To its upper left, by two or three fists at arm's length, shines Deneb. Deneb is the head of the big Northern Cross, which is now swinging down and soon will stand nearly upright on the northwest horizon (as seen from mid-northern latitudes). Sunday, January 13 · In twilight this evening, look below the waxing crescent Moon in the west to see if you can still spot faint little Mars, as shown here. Mars has been hanging in there in twilight ever since August (!) but is now gradually creeping lower week by week. Monday, January 14 · Before moonlight returns in force to wash out low-surface- brightness telescopic objects, try tonight for the Bubble and Pac- Man Nebulae in Cassiopeia using Ken Hewitt-White's "Hot Gas in Cass" article with finder chart and photos in the January Sky & Telescope, page 65.January Sky & Telescope
