A multi-disciplinary study published in Archaeoastronomy Today has provided new evidence linking specific hymns in the Rigveda to a rare astrophysical event. By combining high-resolution stellar simulations with a linguistic analysis of the 'Agastya' hymns, researchers found a precise match between the described celestial luminosity and a supernova event that occurred near the star Canopus (Agastya) in approximately 1850 BCE. The study notes that the texts describe the star as 'twice-born' and 'brighter than the moon,' a description that aligns with the peak magnitude of a Type II supernova.
Led by astronomers from the Tata Institute of Fundamental Research, the project successfully mapped the position of the supernova remnant to the southern sky as it would have appeared from the Saraswati-Drishadvati river basin. This correlation provides a firm observational anchor for the dating of the middle Rigvedic period and confirms the existence of a robust tradition of empirical astronomical monitoring among ancient Vedic observers.
