The aurorae are one of the wonders of the natural world. Using some simple apparatus, they and related phenomena can easily be reproduced in the classroom.
Studying the chemical composition of some of the planet’s oldest rocks has revolutionised our understanding of how our continents formed.
We all know what a kilogram is – or do we? Researchers worldwide are working to define precisely what this familiar unit is.
Finding out what is going on in the core of a fusion experiment at 100 million degrees Celsius is no easy matter, but there are clever ways to work it out.
In the third article in this series on astronomy and the electromagnetic spectrum, learn about the exotic and powerful cosmic phenomena that astronomers investigate with X-ray and gamma-ray observatories, including the European Space Agency’s XMM-Newton and INTEGRAL missions.
Astronomers use giant radio telescopes to observe black holes and distant galaxies. Why not build your own small-scale radio telescope and observe objects closer to home?
With oil reserves running out, silicon solar cells offer an alternative source of energy. How do they work and how can we exploit their full potential?
Physicist Adrian Mancuso works at the cutting edge of 3D imaging, at what will be Europe’s newest and brightest X-ray facility.
During an eclipse, the Sun or the Moon seems to disappear. What is happening? Why not explore this fascinating phenomenon in the classroom, with an easy to build model?
