A Brief History of Astronomy on Merseyside

Jeremiah Horrocks
The region around Liverpool has a great tradition of astronomical endeavour.
This started in the early 17th century with
Jeremiah Horrocks
(depicted right). He was born in Toxteth and made the first telescopic
observation of a transit of Venus across the Suns disk and also correctly
determined the elliptical shape of the orbit of the Moon around the Earth.
This was all achieved before his untimely death at the age of 24.
Horrocks' understanding of the power of the telescope and his use of
specialised mathematical instruments made him a founding father of
modern day observational astronomy.

Liverpool Observatory 19th century
In the early 19th century, the Liverpool observatory was founded to aid in
navigation for the city's burgeoning sea trade.The prime function of the
observatory would be to establish time for the port and test chronometers for accuracy.
A site was initially found at Waterloo Dock in 1845. Later, however, the observatory
transferred to the other bank of the Mersey at Bidston.

William Lassell and telescope
Meanwhile
William Lassell, a local brewer, was building the first large equatorially
mounted reflecting telescopes
(right) and using them to discover several of the moons of
planets in the outer solar system right from the heart of Liverpool.
His elegant cast iron equatorial telescopes were a monument to nineteenth century technology
and entrepreneurial spirit and his influence can still be seen in many national observatories
around the world today.

Historical Picture
Another gentleman astronomer,
Isaac Roberts (a builder by trade whose company built the
Northwestern Hotel, now a hall of residence of JMU), was a pioneer of astronomical photography,
while the physicist
Oliver Lodge was the first to suggest that radio waves might be detectable
from a celestial body (the Sun).
At the centre of much of the activity locally in the 19th century was the Liverpool Astronomical
Society, one of the oldest such societies in the world and the forerunner of the British Astronomical Association.
