In this episode, Astronomy magazine Editor Emeritus Dave Eicher invites you to explore two gorgeous star clusters in the constellation Gemini the Twins: M35 and NGC 2158. M35 is an easy binocular target lying at a distance of 3,000 light-years, while NGC 2158 is around 11,000 light-years distant. Both are great objects to observe and enjoy in the springtime sky. Good luck!
