Dusty samples from the “most dangerous known rock in the Solar System” have been brought to Earth.
The American space agency NASA landed the materials in a capsule that came down in the West Desert of Utah state.
The samples had been scooped up from the surface of asteroid Bennu in 2020 by the Osiris-Rex spacecraft.
NASA wants to learn more about the mountainous object, not least because it has an outside chance of hitting our planet in the next 300 years.
But more than this, the samples are likely to provide fresh insights into the formation of the Solar System 4.6 billion years ago and possibly even how life got started on our world.
