Old objects are usually not to be touched in exhibitions, but the meteorite at Helsinki Observatory is an exception to the rule. Despite being far older than any other object at the Observatory, the public are expressly invited to touch it. To celebrate the 10-year anniversary of the Observatory’s permanent exhibition, our object of the month in October is the meteorite at Helsinki Observatory.
A beautiful old, still-functioning precision pendulum clock hangs on the wall of a corridor leading to the Argelander lecture room at the Helsinki Observatory. This ‘Normal Zeit’ clock used to be placed in the lobby of the Observatory building where it functioned as a public timepiece that Helsinki residents could use to check the time. It is soon again time to turn the clock one hour forward when summer time begins. There are plenty of clocks at the Helsinki Observatory, including several precision clocks, the oldest of which dates back to the 18th century. How are these clocks linked to the Observatory?
