Like many branches of knowledge, the beginnings of astronomy in Bharatavarsha have been traced back to the Vedas. Vedanga Jyotisha text is found in two recensions - Rigveda Jyotisha (called Archa-jyotisha) and Yajurveda Jyotisha (called Yajusha-jyotisha).<ref name=":15">Kolachana, Aditya & Mahesh, Kaluva & Ramasubramanian, K.. (2019). Main characteristics and achievements of ancient Indian astronomy in historical perspective. 10.1007/978-981-13-7326-8_24.</ref> Though the contents of both the recensions are the same they differ in the number of verses contained in them. Rigveda version contains only 36 verses whereas the Yajurveda version contains 44 verses, the difference attributed to the addition of explanatory verses given by the adhvaryu who used them. | Like many branches of knowledge, the beginnings of astronomy in Bharatavarsha have been traced back to the Vedas.
