International Year of Light (IYL 2015)

The International Year of Light and Light-based Technologies, 2015 (IYL 2015) is a United Nations observance that aims to raise awareness of the achievements of light science and its applications, and its importance to humankind.

IYL 2015 is a global initiative adopted by the United Nations to raise awareness of how optical technologies promote sustainable development and provide solutions to worldwide challenges in energy, education, agriculture, communications and health.

At the beginning of the 20th century, Einstein changed the
way we think about Time and Light. Now in the 21st century,
Einstein’s thinking is shaping one of the key scientific and
technological wonders of contemporary life: atomic clocks,
the best timekeepers ever made. Today, atomic clocks are still being improved, using atoms cooled by the pressure of light to incredibly low temperatures. A multimedia presentation at UNESCO Headquarters by the Nobel Prize William D. Phillips.

Asteroid 2004 BL86

A Huge space rock has approached  Earth in a harmless but eye-catching close encounter on Monday night, Jan. 26-27.

This Asteroid is believed to be 740,000 miles away (3.1 times farther from us than the Moon) with a 0.5 km in diameter.

It can be seen by optical aid such as powerful binoculars or a Telescope. Please watch the video below on how and where to look for it in the sky.

This Asteroid “2004 BL86” will be the closest by any known space rock this large until asteroid 1999 AN10 flies past Earth in 2027.
