What direction in the sky is the coordinate of right ascension measured?

Question

What is the range in values of right ascension?

Answer 1

It is measured eastwards around the celestial equator and can take values from 0 to 360° or 0 to 24 hours, depending on the application.

Answer 2

Right Ascension is measured eastwards from the Vernal Equinox. It is usually expressed in hours, minutes and seconds from 0 to 24 hours, although it can be expresssed in degreees (0 to 360). If it's expressed in hours, then the Right Ascension of a celestial object on the local meridian at any given moment is equal to the Local Sidereal Time.
