Varahamihira, a renowned astronomer and astrologer of the 6th century CE, is credited with developing the concept of the zodiac in ancient India.

The armillary sphere was the primary instrument used by ancient Indian astronomers for observing celestial bodies. It is a spherical model of the universe that allows astronomers to measure the positions and movements of stars, planets, and other celestial objects.

Aryabhata, a renowned astronomer and mathematician of the 5th century CE, proposed the heliocentric model of the solar system, which places the Sun at the center of the solar system with the planets revolving around it.

The Surya Siddhanta is an ancient Indian astronomical text that contains detailed observations and calculations of planetary motions. It is considered one of the most important works in the history of astronomy.

Aryabhata developed a method for calculating the circumference of the Earth using trigonometry. His method was remarkably accurate for its time.

The Jantar Mantar is an ancient Indian astronomical observatory that was built in the 16th century by Maharaja Jai Singh II. It consists of a collection of architectural instruments that were used to make astronomical observations.

Brahmagupta, a renowned astronomer and mathematician of the 7th century CE, developed a theory of gravity that was based on the idea that objects fall to the Earth due to an attractive force.
