We may have a new name but it's still time for another BIG and BRILLIANT adventure into the world of science on this week’s Science Quest!

In Science in the News, could a mound in North West England contain the remains of Ivar the Boneless, a lost Viking? We also discover why porpoises go quiet when boats pass by, and hear from Dorota Skowronska-Krawczyk from UC Irvine about how Greenland sharks can live for hundreds of years.

It’s time for your questions too. Lydia wants to know why ice cracks when you put it in water, and Joe Williams from Exeter University helps answer a huge question from Thomas: what caused the Big Bang?

Dangerous Dan introduces us to the unusual Greeningi Frog, and in Battle of the Sciences, Sam Sedgeman explains the fascinating science behind solar eclipses and why they happen.

Plus, join Marina Ventura on her first Ocean Adventure as she explores the exciting world of ocean research.

From the birth of the Universe to mysterious Viking kings and shadowy solar events, this episode is packed with big questions and brilliant discoveries!

What we learn about:

• How scientists think the Universe began

• What might have caused the Big Bang

• How solar eclipses happen

• Why porpoises change their behaviour around boats

• How Greenland sharks live for so long

• Why ice makes cracking sounds

• The mysterious greeningi frog

• How ocean research helps us explore the seas

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