NASA unveils striking images of asteroid Donaldjohanson, a double cone-shaped contact binary that could offer clues to planetary formation

NASA’s Lucy spacecraft made a successful flyby of the second asteroid on its must-see list over the last weekend, and sent back imagery documenting the elongated object’s bizarre double-lobed shape. It turns out that asteroid Donaldjohanson – which was named after the anthropologist who discovered the fossils of a human ancestor called Lucy – is what’s known as a contact binary, with a couple of ridges in its narrow neck. In today’s image advisory, NASA compares the ridged structure to a pair of nested ice cream cones. This is an interesting development for today’s scientific community to say the least. Read on to find out more about this interesting event.

The asteroid has a complex geological composition
