About

When we glance at our wrists to find out the time, we don't even think about the effort and ingenuity that has made it a possibility. From the earliest beginnings with stone circles and sundials, through water dripping and lowering the level in a marked off bowl, to graduated candles that (hopefully!) burned evenly and finally pendulum-driven trickery. And then came the drive from the shipping navigators to be able to accurately tell the time at sea, pendulums being no good in a pitching ship! The huge prize money put up for the first mechanism to solve this drove the invention of the spring-driven clockwork mechanisms still used even in today's world of quartz crystals and electrickery!

Galaxies, Stars and Nebulae series A great outer space picture featuring a three colour composite of the well-known Crab Nebula (also known as Messier 1), as observed with the FORS2 instrument in imaging mode in the morning of November 10, 1999.
It's the remnant of a supernova explosion at a distance of about 6,000 light-years, observed almost 1,000 years ago, in the year 1054. It contains a neutron star near its center that spins 30 times per second around its axis (see below).
In this picture, the green light is predominantly produced by hydrogen emission from material ejected by the star that exploded. The blue light is predominantly emitted by very high-energy ("relativistic") electrons that spiral in a large-scale magnetic field. It's believed that these electrons are continuously accelerated and ejected by the rapidly spinning neutron star at the centre of the nebula and which is the remnant core of the exploded star.
