Astronomers and Sanskrit scholars have collaborated on a paper in the Journal of Astronomical History and Heritage that identifies an encoded record of a Jupiter transit in the Taittiriya Samhita. By applying high-fidelity back-projections of planetary orbits, the team confirmed that a specific ritual sequence described in the Vedic text aligns perfectly with the visual transit of Jupiter across the star Regulus in 2750 BCE.
This finding provides significant support for the observational accuracy of the early Vedic period. It suggests that the authors of the Samhitas maintained systematic records of long-period planetary cycles and utilized them to calibrate their ritual calendars, indicating a level of astronomical sophistication that predates the formal Siddhantic period by over two millennia.
