Goleta CA (SPX) Nov 27, 2015 A team of astronomers have used the LCOGT network to detect light scattered by tiny particles (called Rayleigh scattering), through the atmosphere of a Neptune-size transiting exoplanet. This suggests a blue sky on this world which is only 100 light years away from us. Transits occur when an exoplanet passes in front of its parent star, reducing the amount of light we receive from the star Full article

GUYS. The future is now.
This is the follow-up to squine and cosquine, and I find students find it really cool. Are there any other shapes someone has done this for?
Scientists Make New Form of Gold That’s Nearly as Light as Air
Researchers in Switzerland have been able to produce gold foam that is almost as light as air. In fact, 98% of it consists of air; the rest is made up of 20-carat gold and milk protein. According to materials scientist Raffaele Mezzenga from ETH Zurich, this gold aerogel is a thousand times lighter than any other gold alloy, is lighter than water, and is almost as light as air itself.

Physicists in Germany have built the most accurate timepiece on Earth, achieving unprecedented levels of accuracy with a new atomic clock that keeps time according to the movements of ytterbium ions.
Called an optical single-ion clock, the device works by measuring the vibrational frequency of ytterbium ions as they oscillate back and forth hundreds of trillions times per second between two different energy levels. These ions are trapped within an ‘optical lattice’ of laser beams that allows scientists to count the number of ytterbium 'ticks’ per second to measure time so accurately, the clock won’t lose or gain a second in several billion years.
Until very recently, our most accurate time-keepers were caesium atomic clocks - devices that contain a 'pendulum’ of atoms that are excited into resonance by microwave radiation. It’s on these clocks that the official definition of the second - the Standard International (SI) unit of time - is based.
