A new computational study published in the Journal of Astronomical History and Heritage has linked specific ritual descriptions in the Shukla Yajurveda to a rare celestial event. By employing high-precision astronomical simulations, researchers have confirmed that the 'Krittika-Punarvasu' alignments described in the text correlate perfectly with a Great Conjunction of Saturn and Jupiter that occurred in the constellation of Rohini in 2750 BCE. This provides a new, scientifically-validated chronological marker for the Vedic corpus.
The study argues that the meticulous detail of the planetary positions recorded in the ritual layers could only have been achieved through sustained, multi-generational observation. These findings suggest that Vedic astronomy was significantly more advanced in the 3rd millennium BCE than previously acknowledged, possessing the capacity to calculate the synodic periods of outer planets with enough accuracy to predict their overlapping cycles in the night sky.
