The asteroid Dimorphos just moments before impact.

The DART spacecraft successfully impacted the asteroid Dimorphos in the early hours of this morning (UK time: 27 Sept), and I thought you might want to see what happened!

Please click here to see a video courtesy of BBC News showing the moments just before impact. We will learn in the coming days whether the experiment was successful in changing Dimorphos's orbital speed, and consequently its orbit around Didymos.
