Astronomy

Astronomy has been called the "queen of sciences". It incorporates many disciplines such as physics, particularly optics, mathematics and celestial mechanics. Since ancient times, Muslim scientists have studied astronomy, contributing greatly to human knowledge. Yaqub ibn Tariq, al-Kwarizmi, al-Battani, al-Farghani, al-Sufi, al-Biruni, al-Tusi and Omar Khayyam are just a few of the scholars who have left a lasting mark in the annals of astronomy.

On this page there is a collection of useful links, usenet groups, software and other resources related to astronomy, many with an Islamic flavour.
