...work out why clumpy galaxies have gradually disappeared, and Radio Galaxy Zoo LOFAR, which aims to sort through the state of the art radio data and identify supermassive black holes and starforming galaxies. We are also part of the new REINFORCE collaboration, who will be creating several more citizen science experiments in physics, astronomy and geoscience. In every...

...work inaccuracies. The sand is not easily recycled. Materials: Most metals and alloys (except the reactive and refractory metals such as titanium and tungsten), can be sand cast in air. Cast irons (Fe/1.5–4.5%C) are cast at 1200–1480 ˚C. Grey cast irons contain flake graphite particles, which give good vibration properties. This is to the detriment of strength and...

...work is coming to fruition. Rosetta has now reached the bizarrely shaped rubber-duck comet and it has spent three months mapping its surface in the hope of finding a suitable spot to place its Philae lander. This is a huge feat in itself. It is the first time a spacecraft has entered into orbit around a comet, which is a celestial body with almost no gravity. The images...
