The Turing Test - ComputerphileWhat was The Imitation Game? It inspired the name for the recent Alan Turing's movie but just what was it? Professor Brailsford explains how Turing may have been having a joke on us.

Alien Planet Kepler 186f - A Cousin of Earth490 light years away lies Kepler-186f, a rocky world orbiting a red-dwarf star which is the first definitive Earth-sized planet found in the habitable zone around its parent star, the temperature at which water is at its liquid phase and organic life becomes a possibility.
The announcement of the new Kepler team discovery was in a new report by Dr Elisa Quintana, Thomas Barclay (both interviewed in this video), Jason Rowe and others of the SETI Institute at Nasa's Ames Research Centre, whom you can see more of here https://www.youtube.com/watch?v=UogSOfkoib4
The Kepler exoplanet-hunting telescope run by the National Aeronautics and Space Administration discovered the new planet, one of five in orbit around the red dwarf star Kepler-186. All of the others 186(b-e) are closer to their red sun 186a and are outside the habitable zone
Planet 186f has a radius that is 1.1 times the radius of Earth.
About 70 per cent of all the galaxy's suns are red dwarfs, and these are weaker than our own star in terms of solar power output.
Rocky planets bigger than Earth have more gravity and pull in lots of hydrogen and helium gases that turn them into gassy planets, like Neptune or Jupiter like planets which are common throughout the many solar systems observed across the galaxy.
Smaller rocky planets acquire their atmospheres when gases such as carbon dioxide and water vapour are released by volcanoes. In the rare case when such a rocky planet is within the habitable zone, when water forms then it should remain liquid and would flow across the surface, mixing molecules and acting like the great solvent we know and love thereby giving organic chemistry a chance to thrive.
Given the long life of red-dwarf stars, which burn their nuclear fuel much more slowly than larger stars such as our sun and the giant white and blue stars in our galaxy, gives habitable planets in these systems plenty of time to generate complex life if conditions allow it.
However, even though this planet is in the habitable zone it may not be anything like habitable for humans or even very resilient earth life. Red dwarf stars are often vulnerable to frequent solar flares, without a strong magnetic field to deflect high energy charged particles, the planet would be constantly bombarded with high levels of particle radiation. This would damage some of the very fragile molecules of life, including DNA.
Nevertheless for life to thrive it must evolve, to evolve it must mutate. Some mutations are generated by random high energy particle collisions from the solar wind and cosmic rays. Hence, having a sun prone to flares may help trigger evolution on such a world, perhaps starting it billions of years before its discovery and having let it develop into a myriad of forms.
The Higgs Boson Simplified Through AnimationI think we've all heard about the Higgs Boson at least once since the recent discovery in 2012, but do you really know what it is? Our animated short created for a team animation class in college attempts to simplify the the concept and explain the basics through motion graphics.

Each frame represents one hour. In addition, this visualization shows the Moon's orbit position, sub-Earth and subsolar points, distance from the Earth at true scale, and labels of craters near the terminator.

Alexander Gerst’s Earth timelapsesWatch Earth roll by through the perspective of ESA astronaut Alexander Gerst in this six-minute timelapse video from space. Combining 12 500 images taken by Alexander during his six-month Blue Dot mission on the International Space Station this Ultra High Definition video shows the best our beautiful planet has to offer.
Marvel at the auroras, sunrises, clouds, stars, oceans, the Milky Way, the International Space Station, lightning, cities at night, spacecraft and the thin band of atmosphere that protects us from space.
Often while conducting scientific experiments or docking spacecraft Alexander would set cameras to automatically take pictures at regular intervals. Combining these images gives the timelapse effect seen in this video.
