Indian astronomical texts give the coordinates of the yogataras or junction stars of nakshatras. These coordinates have been interpreted as polar coordinates, which depend on the position of the north celestial pole. Polar coordinates of a star should change with time due to precession. However, different astronomical texts written over many centuries give same coordinates for most yogataras. This has resulted in indian astronomers being called incompetent, who did not observe the positions of the stars with accuracy. Examples of such disciplines include:Astrophysics Galactic astronomy Galaxy formation Cosmology Astrometry Extragalactic astronomy Stellar astronomy Formation of stars Astronomy is the study of the space and all of its amazing moving parts. The study of space, in particular its stars and planets, has a long history, both of assisting farmers to know when it was time to plant and keeping sea faring travelers on the right longitude.
