The modern period of astronomical research really began with the arrival of Dr Eric Mervyn Lindsay as Director in 1937. Lindsay laid plans to enable Armagh Observatory to have access to the best possible photographs of the southern skies. He spearheaded, around 1950, the construction of a 1m telescope at Bloemfontein, South Africa with the cooperation of Harvard University and Dunsink Observatory. Many scientific papers resulted from this collaboration, some of which may be viewed at the exhibition.

The ADH telescope was dismantled in 1976, but recently
Armagh Observatory has joined a consortium to build an
11m telescope in Sutherland, South Africa, the Southern
African Large Telescope (SALT). This telescope, "Africa's Giant Eye," should be operational in 2005, and Armagh Observatory's contribution entitles it's astronomers to have access to it for a period of 10 years.

In the 1940s, Dr Lindsay dreamed of establishing a planetarium in Armagh as a memorial to the American troops who had been stationed in Northern Ireland during the Second World War, and to cater for the growing interest in astronomy. However, it was not until the mid-1960s that he was able to secure sufficient finances to start construction, and he subsequently invited the well-known TV astronomer Patrick Moore to become the first director of the Armagh Planetarium.

While Visiting Professor at Harvard, Dr E.J. Öpik,
the Estonian astronomer, was a member of Dr Lindsay's
doctoral examination board at Harvard University in 1934.
Near the end of World War II, after he had returned to
Estonia, Dr Öpik was forced to become a refuge and
spent 4 years in a displaced persons camp. News of this
reached Dr Lindsay, and he was able to obtain an
appointment for Dr Öpik at the Armagh Observatory in
1948. Dr Öpik remained faithfully at Armagh until his retirement in 1981 at the age of 87.
In 1951, Dr Öpik was one of the first to calculate
the probability of collisions between the asteroids and
the major planets. This research field ultimately
inspired the production of such movies as Deep Impact and
Armageddon. Dr Öpik's grandson, Lembit Öpik MP, remains committed to the understanding of asteroids and the threat that they pose to civilization.
Öpik made seminal contributions to many branches
of astronomy and astrophysics, including cometary
physics and meteors, and the processes involved in the
generation of energy within the stars. The minor planet
(2099) Öpik was named in his honour by its discoverer, Eleanor Helin.
