This article collects and analyzes reports of auroras published in the Extremadura newspaper from 1923 to 2017. We identified 31 articles describing these events, including major auroras in 1926, 1938, 1957, and 1991. This research highlights the value of newspapers in reconstructing past solar activity.

Over the past decade, a vast ancient Lake has been discovered in the central region of Iran, known as the Paleo Mega Lake of Rey. This paper aims to meticulously examine the provided data while accurately pinpointing to this lake. Additionally, significant data related to periods when the lake was filled with water has been acquired. Consequently, there is no longer any room for uncertainty regarding the presence of the lake during the era when humans resided in the territory of Iran.

The meteorite "Veramin" fell in Persia ca. 1880. In the records, there are ambiguities about the event and we therefore scrutinized the available sources. The current official name, coined by meteoricist A. Brezina, is not supported by Iranian documents. A key document is a rediscovered label with the main mass of the meteorite. The indicated place of the event, probably occurring in February–April 1880, is Booghin of in the historical Zarand district, 100 km NW from Veramin (Varamin).

Long-term series of historical observations in Latvia of mesospheric clouds are digitized. Observational data are freely available to researchers. Observation sites, methodology and technical support are described. A brief overview of mesospheric cloud observation statistics 1957–1983.

Karl Terzaghi, reached out to Laurits Bjerrum in 1954, impressed by his paper on Norwegian quick clays' stability. At 36, Bjerrum, already a PhD and NGI director, emphasized practical research integration, influenced by centers like Imperial College London. He advocated for Soil Mechanics in civil engineering education and founded its chair in 1960. Bjerrum left a lasting legacy, earning international acclaim for his NGI work and collaborations with geotechnicals like Terzaghi and Casagrande.

ESA and NASA have distinct technology transfer approaches, including differences in organizational structure, funding mechanisms, intellectual property strategies, international collaborations, business incubation centers, and commercialization focus. However, both agencies share the common goals of maximizing the societal and economic impact of space technologies and fostering innovation through technology transfer.

The Argonauts’ trip along the northern limit of the Libyan Desert, from Syrtis Gulf to Tritonis Lake, is described by Apollonius Rhodes’ text ‘Argonautica’. The Argonauts sailed in this lake and located a narrow passage through which they exit to the Mediterranean’s coast.

Climate science underwent a rapid expansion in the last decades, associated with ever growing significance for climate policy. On the other hand, climate science is, as all sciences, also a social process. Confronted with these developments, several different series of oral interviews with climate scholars, of different seniority, were done and archived. The present article gives an overview of these interviews, and tries to briefly describe the social context of climate science.
