This short video gives an overview of the emergence of the first atoms, hydrogen and helium, 380,000 years after the Big Bang. The effects of gravity led to tiny variations in the density of matter throughout the Universe, which in turn became heated, resulting in fusion and the emergence of the first stars, galaxies, and ...

In the past, astronomers explored the universe with their eyes and optical telescopes, but what they could see was limited. Find out how radio telescopes have revolutionised the way astronomers 'see' the universe, allowing us to explore deeper into space than ever before.Watch this clip to learn about Australia's contribution ...

Using technologically advanced supercomputers, scientists have developed theories about the creation of black holes deep in outer space. Watch the computer simulation in this clip to see how the collision of two neutron stars produces a gamma ray burst and a new black hole. Discover that our continuing understanding of ...

This friendly chat helps to break down some stereotypes about scientists. Jacinta Delhaize travelled to Chile and work at the Gemini South Observatory in the Andes Mountains. She talked about her experience with high school students and for this received the Science Student of the Year award in 2008. Her PhD researches ...

This nine and a half minute video segment from Catalyst explains that relatively recently times we have got the technology to look for exoplanets. Astronomers have now uncovered more than 350 planets orbiting other stars. These worlds, known as exoplanets, can be pretty weird places. This program discusses a theory to describes ...

This 13 minute video in 3 parts explains how the Big Bang theory developed by looking at the evidence that supports it, including Hubble's theory of the birth of the universe, Hoyle's naming of it and Einstein's theory of energy and matter. Part 2 looks at what happened after the Big Bang - the emergence of the 4 fundamental ...

This radio interview gives examples of how improvements in technology have influenced astronomy. The Space Shuttle Atlantis is paying a service call to the Hubble Space Telescope, repairing, replacing and deploying new equipment. Jonathan Nally describes the mission and looks at other large telescopes in orbit now, and ...

This is an interactive resource about how greenhouse gases affect the climate. Students use a simulation to explore the atmosphere during the ice age and today. They change variables such as adding clouds, changing greenhouse gas concentrations and see how the temperature changes. They can then compare this to the effect ...
