The agency says that the angle of the sunlight that strikes its tracks creates glare that blinds the CCTVs that train-drivers use to ensure that the platform is clear before pulling out of the station. Read the rest

For amateur astronomers, tonight is an exciting night.
Oscar Lhermitte and Kudu's MOON lunar globe eclipses every other Kickstarter project currently underway.
MOON is the most accurate lunar globe, using NASA's Lunar Reconnaissance Orbiter topographic data combined with electronic and mechanical engineering alongside careful craftsmanship in mold making.
MOON is unlike traditional lunar globes that uses 2D photographs or illustrations of the Moon.
1. it is a truly accurate 1/20 million replica of the Moon featuring all the craters, elevation and ridges in accurate 3D.
2. it has a ring of LED lights that revolves around the globe, constantly illuminating the correct face of the moon and recreating the lunar phases as seen from Earth.
The combination of the 3D terrain with a light source is what makes it unique. By projecting the light onto the Moon, all the craters, ridges and elevations are brought into relief by their shadows. This recreates the lunar features as we see them from Earth.
For the first time, MOON allows you to see the side not visible from Earth ("dark side of the Moon" or "far side" to be scientifically correct).
Tom writes, "Scientists at Northern Arizona U. use a home-made machine to create 'exotic ices.' They're simulating the surface of Pluto to help explain data and pictures sent to Earth by the New Horizons spacecraft." Read the rest
