Question

What development took place in the field of astronomy in medieval india?

Answer 1

Some of the earliest forms of astronomy can be dated to the period of Indus Valley Civilization, or earlier.[1][2] Some cosmological concepts are present in the Vedas, as are notions of the movement of heavenly bodies and the course of the year.[3] As in other traditions, there is a close association of astronomy and religion during the early history of the science, astronomical observation being necessitated by spatial and temporal requirements of correct performance of religious ritual. Thus, the Shulba Sutras, texts dedicated to altar construction, discusses advanced mathematics and basic astronomy.[11]Vedanga Jyotisha is another of the earliest known Indian texts on astronomy,[12] it includes the details about the sun, moon, nakshatras, lunisolar calendar.[13][14]Indian astronomy was influenced by Greek astronomy beginning in the 4th century BCE[6][7][8] and through the early centuries of the Common Era, for example by the Yavanajataka[6] and the Romaka Siddhanta, a Sanskrit translation of a Greek text disseminated from the 2nd century.[9]

Indian astronomy flowered in the 5th-6th century, with Aryabhata, whose Aryabhatiyarepresented the pinnacle of astronomical knowledge at the time. Later the Indian astronomy significantly influenced Muslim astronomy, Chinese astronomy, European astronomy,[10] and others. Other astronomers of the classical era who further elaborated on Aryabhata's work include Brahmagupta, Varahamihira and Lalla.

An identifiable native Indian astronomical tradition remained active throughout the medieval period and into the 16th or 17th century, especially within the Kerala school of astronomy and mathematics.
