Checking out the Goldilocks Zone. With a team of astronomers and astrophysicists, Big Ideas is exploring the skies — more precisely, exoplanets that orbit around stars beyond our solar system in what is known as the Goldilocks Zone. It's the zone with conditions that might be just right for creating life. What is this zone, what is being discovered and what can we learn about our own terrestrial world?

Hunting for life on exoplanets — but is it life as we know it?

Where is the soul in science?

When you're faced with the reality that your home, livelihoods and culture will be swallowed up by the rising seas of a warming climate, how do you respond?

Not drowning, fighting — life on the front lines of the climate crisis

You might think humans have escaped biology and evolution altogether with our strange and different ways: Women live well past their reproductive years, and we have baffling long childhoods as a species. We display a dazzling mix of selfishness and altruism, and gossiping can in fact be a strategy for survival.

Evolution can explain why humans are such weird animals

As violence continues in Europe and the Middle East and as positive collective action on urgent global-scale issues seems out of reach, do we need new forms of international cooperation? How can Global South and Global North nations work together more effectively? What roadblocks hinder joint action on crucial issues such as security, development, climate, and AI? How can ethical reflection and engagement pave the way for a more inclusive and equitable multilateralism? A panel of international policy experts believes it's possible: There are shared values and shared interests that can serve as the basis for effective and inclusive forms of cooperation; we merely need to activate them.
