If you’ve ever dreamed of living on Mars, you’ve probably realised you’ll need a place to live. That’s one reason to be excited about Martian brick research being conducted by scientists in the United States. Recently, a team showed that it’s actually quite easy to make bricks out of Mars dirt. But how did they get the dirt to test in the first place?
Mars is a long way away from Earth. Which is why every mission to Mars has been a one-way trip. Scientists have never sent a sample of Mars back to Earth. But decades of experiments on rovers, landers and orbital spaceships means we know quite a lot about Martian dust. Continue Reading →

Iceland is a remote and beautiful island, brimming with volcanoes. Volcanic eruptions give the Earth an almighty shake, so it’s no surprise that Iceland has lots of earthquake measuring seismometers. But you might be surprised to find out what these instruments are picking up.

Welcome to the four newest members of the periodic table!
The periodic table doesn’t change very often, which is why it’s worth celebrating when it does. This month, three new elements were inaugurated at a ceremony in Russia. And in Tokyo, a fourth was welcomed to the world. Say hello to moscovium, tennessine, oganessson and nihonium!
Let’s back up a bit: what is an element? Elements are the different types of atoms that exist. So oxygen is an element, and hydrogen is an element, but water is not – it’s a chemical made of oxygen and hydrogen atoms. Continue Reading →
