Movies and public lectures on astronomy & astrophysics.
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?
We'll take a journey through the Solar System - from the Sun, to Neptune. We'll stop at some moons along the way and some of the smaller things in our Solar System.
How do stars form, where does the solar system come from, what are moons and how did ours get there?
We will talk about how the Earth, Sun, and Moon all work together. We'll touch on day/night, seasons, and the phases of the Moon. We'll do a demo of the phases and seasons that you can do at home, not only for the Moon but other planets! We'll also talk about viewing the phases of the Moon and Venus this month.
40 years ago the Voyager spacecraft hurtled towards the furthest regions of our solar system. On board was a golden record with the sounds and songs of Earth. If you were to choose a song to go on a new Voyager mission what would it be?
Would we have an obligation to help alien species?
