Far smaller and closer to the Sun than it should be, Mercury has long baffled astronomers because it defies much of what we know about planet formation. A new space mission arriving in 2026 might solve the mystery. At a cursory glance, Mercury might well be the Solar System's dullest planet.

Here's how to spot hidden sugars and what to do about it. read more
