Fraser CainWhen NASA's Lucy mission made its first flyby of asteroid Dinkinesh last week, it made the surprising discovery of a tiny moonlet. Well, hold onto your hats; a new picture from Lucy is mindblowing. That moonlet is two tiny moons gently resting side by side. This configuration is known as a contact binary, and it's very common in the Solar System, but we've never seen one up close like this and never orbiting another asteroid. If only Lucy could stick around.
