New asteroid article in Sky At Night Magazine

I have a new article in Sky At Night Magazine this month, about asteroids, addressing a topic that I’ve often wondered about and one I’ve heard asked about quite a lot recently (especially after things like this happen) — “why do we miss some spacerocks and why do we spot some of them so late?”. It turns out there are a few reasons, and thankfully there are several things that are being done about it. If you want to get the whole story though you’ll have to see pages 39-43 of the June issue.
