After exploring most of Earth, venturing into space and exploring other planets, stars and galaxies seemed like an exciting, and even obvious next step. But the deeper we look, the more the universe reveals a hidden barrier between our Solar System and everything else around it. From the vast empty space, to the laws of physics themselves, there are many reasons why the dream of space travel might stay just a dream.

What is stopping us from reaching the stars? Why does space become more dangerous the faster you travel, and could even advanced alien civilizations be trapped around their home worlds?

Back in 1932, Australia went to war against the most unusual enemy. It wasn't another country or an invading army. It was a flock of 20,000 emus! They invaded and devastated farmers' wheat fields and the government had no other option but to take out the big guns, literally. What followed has since become one of the strangest military operations in the history: the Great Emu War.

So what actually happened during the Emu War, and how did one of the world's largest birds outsmart machine guns? And most importantly, who won?

Memory is one of the strangest abilities you possess. Your brain uses an incredibly complex biological system to preserve moments from your past that no longer exist, allowing you to revisit experiences from years ago. But memories are not always recordings of reality. In fact, every time a memory comes under the spotlight of your attention, it can melt and change a tiny bit.

What exactly is a memory, how is a moment in time stored inside your brain, and why does remembering something slowly rewrite the story of your life?

Earth may seem like the perfect planet for life, but huge parts of our planet are actually hostile deserts of ice, rock, heat or darkness. Even our oceans are mostly barren voids where almost nothing can survive. But as we discover and research more exoplanets, we are beginning to wonder whether there could be worlds that are far better suited for life than Earth ever was, and where ecosystems flourish on a scale we can barely even imagine.

Could there be a Super-Earth that is not just habitable, but truly ideal for life? What would such a world look like, and what kinds of creatures would we find there?
