Free public lecture in Hobart
Manager of the Launceston Planetarium Martin George will deliver an intergalactic free public lecture at UTAS this May, titled: A little black dot: the transits of Venus.
Only the planets Mercury and Venus can pass between the Earth and the Sun. These events are called transits, during which we see these planets appearing as circular black dots appearing to slowly move across the Sun's face.
Although transits of Mercury happen about 13 times each century, transits of Venus are rare. They occur in pairs separated by eight years, following which the next pair occurs more than a century later.
On the sixth of June this year, Venus transits the Sun for the last time until the year 2117!
In the past, the transits were very important, as they were used to calculate the distance between the Earth and the Sun.
Today, we have no need of this method. However, the rarity of these events and the colourful history of their observation capture public attention. Both great successes and bad luck were experienced by intrepid astronomers and explorers of the 18th and 19th centuries.
In this talk, Martin George will excite everyone with the fascination of the transits of Venus, and discuss what we shall see this year - weather permitting!
