Description

This week we say goodbye to Comet SWAN as it disintegrates on its first — and last — visit to the inner solar system. With a New Moon offering ideal stargazing conditions, we turn our attention to the Summer Triangle, Venus and Saturn’s pre-dawn pairing, and Mars dances near the Beehive Cluster.

In the second half, we spotlight the galaxy’s rebellious loners: runaway stars. From the aftermath of supernovas to gravitational billiards near black holes, discover how some stars break free and speed through space at hundreds of kilometers per second. We’ll explore how they’re formed, how we find them, and why stars like HV 2112 and Zeta Ophiuchi continue to baffle and amaze astronomers.
