Movies and public lectures on astronomy & astrophysics.
A close look at a very distant and surprisingly active world, with icebergs the size of mountains, knifeblade ridges kilometres high, and a sea of nitrogen slushie.
Introducing basic equipment commonly used in amateur astronomy (aka stargazing), and learn how to choose your first telescope!
To get an explosion big enough to send a rocket into space we need rocket fuel, made of HYDROGEN. Next time you want to travel to outer space, don’t take your rocket to a refuelling station! Instead, make your hydrogen at home with this simple experiment, using things you can find around your house.
How are stars born? How do they die? And just how big are they? These questions and more answered in this brief talk on the lifecycle of stars.
How many megatonnes of TNT would it take to blow up a star?
Space lasers, re-usable rockets, and space mining. They all may sound like science-fiction but they are closer to reality than you may think. We'll cover the latest in space technology and advancements, and look at things like humans returning to the Moon and moving to Mars.
Telescopes are big, but sometimes even the largest telescopes in the world aren't big enough. How do astronomers solve this problem? Telescope teamwork! By combining the light from multiple telescopes, we're able to see the Universe in astonishing detail - including its stars, galaxies, and even black holes!
What happens when you add milk to your hot chocolate? It's something called turbulence - and this turbulence can shake aeroplanes and churn space gas to make bright shining stars. In this talk, we will discuss what turbulence is, how big it can get, and what it can do in stars and big galaxies!
What are black holes? How are they formed? What do we know about them? We'll cover the latest discoveries in black holes - from the first image of them to detecting their collisions.
How do astronomers look back in time? And when we do, what do we find out about the Universe's childhood?
In this talk, Alex will discuss the amazing worlds in our own solar system and beyond, how they formed, how they were discovered and answer the question: is our solar system unique?
