Water found on alien worlds

The Hubble space telescope has recently detected water in the atmospheres of five distant planets. The planets are all massive Jupiter-sized bodies that orbit close to their host stars. But their extremely high temperature means that the chances of life, or at least life as we know it, is low.

However this research does open a whole number of doors into our investigation of different atmospheres of various exoplanets beyond our solar system, and ones that could potentially . The compositions of the atmosphere can be determined by the wavelengths of light that the host star transmits and the wavelengths that are partially absorbed. This study also revealed a layer of haze or dust around the planets.

The Science of Curling

Team GB are in action at the Sochi Olympics against China at the moment, but how does curling actually work?

Players push 18kg granite 'stones' some 30m across the ice towards the target. The ice is 'pebbled' by spraying the ice with water to form bumps as it freezes. The stone has a handle on so players can tweak the stones angle, meaning that it spins as it travels towards the target. The path of the stone curves to the right with a clockwise spin and left for an anticlockwise spin. But how do you win at curling? 

Whilst it may look odd, sweeping ahead of the stone is essential. The action reduces the friction by increasing the temperature and softening the ice, allowing the stone to travel longer. Hopefully to knock out the opponent's stone.

China actually won against Team GB 7-6, which, thanks to Denmark puts us into the play-offs tomorrow  - COME ON TEAM GB! :)
