The empire's chief astronomer, <a href="/wiki/Taqi_ad-Din_Muhammad_ibn_Ma%27ruf" title="Taqi ad-Din Muhammad ibn Ma'ruf">Taqi ad-Din</a>, petitioned the Sultan to finance the building of a great observatory to rival <a href="/wiki/Ulugh_Beg" title="Ulugh Beg">Ulugh Beg</a>'s <a href="/wiki/Samarkand" title="Samarkand">Samarkand</a> observatory.

Much like a modern institution, the main building was reserved for the <a href="/wiki/Library" title="Library">library</a> and the living quarters of the staff, while the smaller building housed a collection of instruments built by Taqi ad-Din. These included a giant armillary sphere and an accurate mechanical <a href="/wiki/Astronomical_clock" title="Astronomical clock">astronomical clock</a> for measuring the position and speed of the planets. With these instruments, Taqi ad-Din had hoped to update the old astronomical tables describing the motion of the planets, sun, and moon.<sup id="cite_ref-HotW_1-1" class="reference"><a href="#cite_note-HotW-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>The observatory did not survive to advance the development of astronomy in the Muslim world. Within months of the observatory's completion, a <a href="/wiki/Comet" title="Comet">comet</a> with an enormous tail appeared in the sky and Sultan Murad III demanded a prognostication about it from his astronomer. "Working day and night without food and rest" Taqi ad-Din studied <a href="/wiki/Great_Comet_of_1577" title="Great Comet of 1577">the comet</a> and came up with the prediction that it was "an indication of well-being and splendor," and would mean a "conquest of Persia".
