In 2021, we launched a space telescope that's 100 times more powerful than Hubble, called the James Webb Space Telescope. How does the JWST work? What makes it so powerful? And what might it see?

Thanks to the Hubble Space Telescope, we have seen nebula like never before. But are they really as colourful as Hubble makes out?

The Hunga Tonga-Hunga Ha'apai volcano's eruption in January 2022 was one of the largest ever captured on camera, with a massive ash cloud, over 200,000 lightning strikes, and a shockwave that traveled around the globe. The eruption had...

A black body is a theoretical or imaginary object that perfectly absorbs all incoming electromagnetic radiation, and also emits radiation, like heat and visible light, based on its temperature. A black body is considered theoretical...

Though often used more narrowly to refer to ionising radiation, the term radiation refers to any form of energy that travels through a medium, radiating outwards from a source.

From radio waves to gamma rays, the electromagnetic spectrum is useful in different ways. How does this radiation differ and how can they be used? Physics - Waves - Learning Points. Electromagnetic radiation exists along a continuous...

We use two cans, one painted black and the other painted white, to investigate heat absorption. The containers are placed in front of a heat source and the temperature change is recorded. This shows that the black container absorbs heat...

We compare two cans, one painted black and the other painted white, to see how quickly they lose heat. The containers are placed in front of a heat source and heated to the same temperature. The temperature in each container is recorded...

We use a prism to split white light into its constituent colours. Light is passed through a slit in a screen before it hits the prism. The prism refracts the light and we can see the different colours. A second slit can be used to see...
