In this episode, Astronomy magazine Editor Dave Eicher invites you to head out and observe M4, the wonderful globular cluster in the constellation Scorpius the Scorpion. You can use the Scorpion’s brightest star, 1st-magnitude Antares, as your guide. Although sharp-eyed observers may pick this up with their naked eyes, its swarms of stars look best through a telescope. Good luck!
