Penteli Observatory

<p>The Penteli Observatory , also known as the Penteli Astronomical Stationis (Αστρονομικός Σταθμός Πεντέλης), is an <a href="/facts/Astronomical/0ArJVM1p">astronomical</a> <a href="/facts/Observatory/y0FVg7vS">observatory</a> in <a href="/facts/Penteli%2c_Greece/4nfEr6En">Penteli</a>, <a href="/facts/Greece/lqHw8bTB">Greece</a>, operated by the <a href="/facts/National_Observatory_of_Athens/IWwt8wBl">National Observatory of Athens</a>. It is best known for housing the historic <a href="/facts/Newall_Refractor/KmmHypSg">Newall Refractor</a>, which was the largest refracting telescope in the world when it was built in 
1869. From 1959 to 1980 it was a major site for scientific research, though since then it has been facing severe <a href="/facts/Light_pollution/AD03VyzX">light pollution</a> problems resulting in its gradual conversion into a <a href="/facts/Public_observatory/o6Ac1WFy">public observatory</a>, especially after the establishment of the Visitor Center there in 1995. Nowadays, the most notable research conducted in the location is the one carried out by the Athens Digisonde, an <a href="/facts/Ionosonde/V8uN7vyr">ionosonde</a> used for <a href="/facts/Ionospheric_sounding/xfQEAqgv">ionospheric sounding</a>.
