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!

Carina Nebula pretty image from space Wrist Watch


Ad: Carina Nebula pretty image from space Wrist Watch

Galaxies Stars and Nebulae series: Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7 500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis the ship of Jason and the Argonauts from Greek mythology).
