On the famous figural mosaic, a huge hydraulic wheel was discerned. According to Prof. Marek T. Olszewski, it is currently known as the oldest representation of a noria.

An Earth-sized rogue planet discovered in the Milky Way

Our Galaxy may be teeming with rogue planets, gravitationally unbound to any star. An international team of scientists, led by Polish astronomers from the University of Warsaw, has announced the discovery of the smallest Earth-sized free-floating planet found to date.

The Denouement of the Enigma of the Roman Mosaic from the House of Aion in Paphos

After years of research conducted by Prof. Marek T.
