We're having so much fun listening back through your all-time favourite Imagine This episodes! This one sure was illuminating! The Sun is hot and bright, it helps plants grow and keeps us warm. But…
Lisa Harvey-SmithGuestNijHostHow does the sun light up the whole world?
Hmm, what do you think?
Um, because it's big.
It's really, real big.
Because it's really hot fire on it.
I think it's hotter than fire, or lava, I think.
Who should we talk to about the sun?
I think we could talk to a scientist.
A person who knows a lot about the sun.
Yeah.
She's an astrophysicist.
Astrophysicist?
Astrophysics is a type of astronomy, the science of stars.
The sun is a very big star.
Yeah.
Come on, I bet we can find Lisa at the observatory.
