What's Happening?
Astronomy Magazine has provided guidance for observing the open cluster M103 in the constellation Cassiopeia, known as the Queen. M103 is a young open cluster of stars, identifiable at magnitude 7.4, located
1° northeast of Delta Cas. The cluster spans approximately 6' in angular diameter and contains several dozen bright stars. It is positioned between 8,000 and 9,000 light-years from Earth and is estimated to be between 9 and 25 million years old. A prominent central red giant is a notable feature of M103. The magazine also notes a celestial event involving Titan's transit across Saturn on November 6, 2025. Astronomical ephemerides for November 6 include sunrise at 6:36 A.M., sunset at 4:50 P.M., moonrise at 6:22 P.M., and moonset at 9:29 A.M., with a 90% waning gibbous moon phase specified for 40° N 90° W.
Why It's Important?
