Archaeoastronomers have identified a remarkable correlation between specific hymns in the Rigveda and a rare astronomical event that occurred over 4,000 years ago. By utilizing high-resolution celestial simulations, the study links descriptions of the 'Great Lion' and the star Regulus (Magha) to a planetary conjunction of Jupiter and Mars that took place in the constellation of Leo during the spring equinox of 2400 BCE.
The research, published in the Heritage Science Journal, argues that the precise linguistic encoding of these celestial positions serves as a chronological marker for the composition of early Vedic ritual layers. This findings challenge current timelines for the development of Indian astronomy, suggesting a tradition of rigorous observational record-keeping that predates the formal Siddhantic period by several millennia.
