We spoke to the science journalist Abigail Beall - author of The Art of Urban Astronomy - about what the changing seasons means for the night sky, how to spot planets and constellations, and how to get started with stargazing this winter. Abigail Beall is a freelance science journalist covering space and physics for places like New Scientist, Wired UK and BBC Future. She is a keen stargazer and author of The Art of Urban Astronomy.
