In the Next Issue

In our September/October issue, we’ll bring you up to date on the mysterious class of black holes that are heavier than exploded stars but lighter than those in galactic hearts. We’ll also introduce you to a group of amateur astronomers that hunts for lost satellites, sometimes helping space agencies re-establish contact with them.
