Nasa’s Fly-by of Ultima Thule, the most distant visited object in our solar system

It has been years in the planning and involved a tiny window of opportunity. Nasa’s New Horizons mission launched in 2006 has reached its far flung destination, a couple of outer space snowballs known as Ultima Thule. The mission aims to shed light on the formation of our solar system.

 And just days later an unmanned Chinese mission has landed on the moon, on the far side, they’ll be examining rocks and also seeing if simple plants and animals survive in a biosphere there. 

We also look at the Indonesian Anak Krakatau volcano, which has erupted recently. Just why did it collapse into the sea creating a tsunami, and why is it so difficult to predict the impact of volcanic eruptions?

And we celebrate the periodic table,150 years old this year, this chart of chemical elements found on the walls of classrooms around the world still has much to reveal.
