Royal Observatory Astronomer Dhara Patel explains how we can use telescopes to capture light from the vast expanse of space to better understand our Universe.
With astronomy being a science heavily reliant on observation, it seems mind-boggling that astronomers have gained so much knowledge about the universe from just ‘looking’. Join Dhara Patel of the Royal Observatory Greenwich to explore how light can be collected and analysed to make sense of the Universe and understand how astronomers are able to see the things that we normally wouldn’t be able to!
The following questions will be discussed in this course:
- What is light?
- How do telescopes work?
- How do we know what things in space are made of, how hot or cold they are and that the Universe is expanding?
- Other than observation, how can we learn about the Universe?
