Scientists found signs of organic molecules in the first samples of potentially hazardous asteroid Bennu, as well as a 'head scratching' material that has yet to be identified.

A sample from the asteroid Bennu, collected by the OSIRIS-REx mission, has arrived at London's Natural History Museum for analysis. Scientists are optimistic that it could contain the seeds of life.

In the glare of the sun, an unknown number of near-Earth asteroids move on unseen orbits. A new generation of space telescopes could be our best defense against potential disaster.
