Earth, Moon and Planets was a book written by Fred Lawrence Whipple and originally published in 1947. It has 302 pages. The book covers various aspects of the Earth, Moon, and planets within our solar system, like the physical characteristics of these bodies, their orbits, geological features, atmospheric properties, and the processes that shaped them.

This fond consist of the newspaper clippings on the coverage related to Halley comet.

The fond contains newspaper clippings related to Kalki from 1987-08-10 to 1988-03-19

The book "Numerical Lunar Theory" was written by ?Sir George Biddell Airy. It was published in ?1886. The book focuses on lunar theory, specifically the mathematical and numerical calculations involved in understanding the ?moon's motion and its relationship with the Earth and other celestial bodies. It covers gravitational forces, orbital calculations, and the effects of perturbations on the moon's motion. It was 178 pages long.

The observation note of Madras Equatorial observations on partial solar eclipse, lunar eclipse, occultation of planets and other astronomical objects. This fond significantly describes the disvoery of several planets, their regular activities, and changes and various astronomical phenomena. From these observations several detections were acrried out through screw detection techniques, interval analysis, and finding mean postitions of various stars.

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.

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.

This fond contains photographic plates of Comet Halley in 1987 viewed from Kavalur using the 90" telescope under various atmospheric conditions
