Aryabhata, a renowned Indian astronomer and mathematician, proposed the heliocentric model of the solar system, where the Sun is at the center and the planets revolve around it. This model was a significant departure from the prevailing geocentric model and laid the foundation for modern astronomy.

The Surya Siddhanta is an ancient Indian astronomical text that presents a comprehensive system of astronomy. It covers topics such as planetary motion, eclipses, and the calculation of time. The text had a profound impact on the development of astronomy in India and influenced astronomical thought in other cultures as well.

Sanskrit was the primary language used by Indian astronomers to document their observations, theories, and calculations. Many significant astronomical texts, including the Surya Siddhanta and the works of Aryabhata, were written in Sanskrit.

Brahmagupta, an Indian mathematician and astronomer, is widely recognized for his contributions to the development of the concept of zero and its incorporation into the decimal system. This innovation had a transformative impact on mathematics and astronomy, enabling more accurate calculations and facilitating the advancement of scientific knowledge.

Indian astronomy had a multifaceted impact on the development of astronomy in the Islamic world. The translation of Indian astronomical texts into Arabic made Indian knowledge accessible to Islamic scholars. Cultural exchanges between Indian and Islamic scholars facilitated the sharing of ideas and techniques. Additionally, the establishment of observatories in Islamic cities provided a platform for astronomers to conduct observations and further advance astronomical knowledge.

The heliocentric model of the solar system, proposed by Indian astronomers such as Aryabhata, was eventually adopted by European astronomers. This model, which places the Sun at the center of the solar system with the planets revolving around it, became a cornerstone of modern astronomy and revolutionized our understanding of the universe.

Indian astronomy made significant contributions to the development of navigation and exploration. Indian astronomers created accurate star charts and navigational techniques that aided sailors in determining their position at sea. They also developed instruments for measuring latitude and longitude, enabling more precise navigation. Additionally, observatories established along trade routes provided valuable data for astronomers and navigators.

The concept of the zodiac and the division of the sky into constellations, as developed by Indian astronomers, had a profound influence on the development of astrology in various cultures. The zodiac, with its twelve signs, became a fundamental component of astrological practices, shaping beliefs about the influence of celestial bodies on human affairs.

Indian astronomy made significant contributions to the study of time and the development of calendars. Indian astronomers developed accurate methods for calculating the length of the year and the day, leading to the creation of calendars that incorporated astronomical observations. Additionally, the establishment of observatories allowed astronomers to track the movement of celestial bodies and refine their understanding of time.

The theory of planetary motion developed by Indian astronomers, particularly the work of Aryabhata, had a significant influence on the development of astronomy in China. Chinese astronomers adopted and adapted Indian astronomical models and techniques, which contributed to the advancement of astronomical knowledge in China.

Indian astronomy influenced the development of astronomy in Southeast Asia through multiple channels. Cultural exchanges and the spread of Indian texts introduced Indian astronomical knowledge to Southeast Asian scholars. The establishment of observatories in Southeast Asian countries facilitated astronomical observations and research. Additionally, collaboration between Indian and Southeast Asian astronomers further enriched astronomical knowledge and understanding.

The heliocentric model of the solar system, proposed by Indian astronomers such as Aryabhata, was eventually adopted by European astronomers. This model, which places the Sun at the center of the solar system with the planets revolving around it, became a cornerstone of modern astronomy and revolutionized our understanding of the universe.

There is no evidence of direct influence or contribution of Indian astronomy to the development of astronomy in the Americas. The astronomical knowledge and practices of Native American civilizations were largely independent of Indian astronomy.

There is no evidence of direct influence or contribution of Indian astronomy to the development of astronomy in Africa. The astronomical knowledge and practices of African civilizations were largely independent of Indian astronomy.

There is no evidence of direct influence or contribution of Indian astronomy to the development of astronomy in Australia. The astronomical knowledge and practices of Aboriginal Australian cultures were largely independent of Indian astronomy.
