It's time for another BIG and BRILLIANT adventure into the world of science on this week’s Science Quest!

In Science in the News, Earth’s climate is now more out of balance than at any point in recorded history, with the planet gaining more heat than it can release. We also explore a surprising Iron Age discovery that has stunned scientists, before heading into deep space to investigate a newly discovered type of liquid planet, as Harrison Nicholls from Oxford University explains what it could reveal about worlds beyond our own.

It’s time for your questions too. Toby wants to know how the science behind the Northern Lights, and Dr Scott Paterson answers Rocco’s question: about why humans have bones and what they actually do?

Dangerous Dan introduces the Spanish Ribbed Newt, a creature with a truly unusual defence mechanism.

And in Battle of the Sciences, astrobiologist Dr Vic Pearson takes us on a journey beyond Earth to explore the search for life elsewhere in the universe.

Plus, Professor Hallux is back with Bones and Skeletons, putting his brand-new invention to the test as he discovers what our skeleton really does and why we need it.

What we learn about:

• Why Earth’s climate is becoming unbalanced• A newly discovered type of liquid planet• How the northern lights are created• Why humans have bones and what they do• The Spanish Ribbed Newt• How scientists search for life beyond Earth

All that and more on this week’s Science Quest!
