This week on Astronomy News with The Cosmic Companion, we learn how gravitational waves show evidence for a pair of ancient stellar murder mysteries, we meet a white dwarf the size of our Moon, and we pay a visit to our ailing friend, the Hubble Space Telescope.  This week's scheduled interview with Earl Swift, author of Across the Airless Wilds, has been postponed until July 20, due to technical problems. Make sure to join us then for an inside look at NASA's lunar buggy!   Listen to the podcast version of this episode here, or watch the video version of this episode at: https://youtu.be/60amV2NtG_cCatch up on every episode of this show at: www.thecosmiccompanion.tv!
