In the last six months, my editorial life has been dominated by the cosmos. I’ve explored images of theoretical white holes; contemplated the nature of time and whether we can travel through it; learned about volcanic moons and potential life on planets other than our own. Enter National Geographic’s Are We Alone? and Other Mysteries of Space. Managing this project was a lot of fun, and really pushed my knowledge of what we know–and how much we still don’t know–about our universe and beyond.
