The item has two photographs captured during the Directors' conference at Kodaikanal held on 1st January 1953. The first is showing the directors who participated in the conference. The second photo shows the directors and observatory staff.

The item is a group photo of Dr. Anil Kumar Das, Prof. K. R. Ramanathan, and other employees of the Kodaikanal Observatory with astronomer Royal from Kodaikanal Observatory in 1947. K. R. Ramanathan was an Indian physicist and meteorologist. He was the first Director of the Physical Research Laboratory, Ahmedabad.

This item was about the pencil sketches of solar prominences drawn by John Evershed.

This item was a pencil sketch drawing of Prof.M.K.Vainu Bappu by A.P.Jayarajan

The document is a pay slip of Thomas Royds for the month of March in 1916, Issued by the Assistant Account General office, Madras. During that time he was working as Assistant Director of Kodaikanal Observatory.

This is the last pay certificate for K.V. Sivarama, 1st assistant at the Kodaikanal Observatory.

This letter was about Kodaikanal Observatory's position & surroundings and also talks about scientific celebrities contribution and visits of Dr. Homi Bhabha, Dr. S. Chandrasekhar.

The Observations conducted at Kavalur during the 10 March 1977 Uranus occultation of SAO158687 revealed, apart from the occultation by a satellite system known as the e ring, a decrease in the star's brightness near the moment when the planet's atmosphere could have triggered the occurrence. Since then, a theoretical explanation for the genesis of the a, ß, ?, and d rings has been put out in addition to the identities of these rings becoming firmly established. After thoroughly analysing the Kavalur photoelectric record, they provide several novel elements of Uranus' satellite ring system.

Astronomer William Stephen Jacob of India made important advances in the study of Saturn. He made observations of the Sunnian system and reported his findings, which included determining the elements of Saturn's satellites and Jupiter's adjusted mass. In 1852, he and William Lassell observed the transparency of Saturn's "dusky ring" almost simultaneously. In 1861, James Breen truncated Jacob's planetary observations. The Indian government paid for the printing of his books on the Saturnian system. Important new information about Saturn and its moons was made possible by these observations and calculations. One of his best-known pieces is a sketch he made on November 15, 1852, of Saturn. Using the Madras Equatorial, this drawing was created. W. Forrest then etched it. The illustration caught the appearance of Saturn on that specific date, providing valuable insights into the planet's features and characteristics at that time.

This item was the painting of Kodaikanal Observatory by an unknown artist in 1909.
