How can I convert Right Ascension and declination of a galaxy to distances in parsecs or any other common form?
Can you explain Right Ascension and declination in more detail?
Right Ascension is the east-west coordinate of a celestial body, measured in hours, minutes, and seconds, from the vernal equinox. Declination is the north-south coordinate, measured in degrees, minutes, and seconds, from the celestial equator.
