When we gaze at the clear blue sky, we do not realize the staggering amount of trash that is out there, orbiting the Earth.

During a Polish Antarctic Expedition to Dobrowolski Station the astronomic co-ordinates of a main geodetic point have been determined. The observations were performed by Kavrajski's method. In result 26 pairs of bright stars were observed. Longitude and latitude were defined with an estimated accuracy about ± 1".

Gravitational waves are not a rare phenomenon that happens only once in a while in our universe. Rather, such waves pass through the Earth on a daily basis, generated by cosmic events of various types. Studying their origins can teach us a great deal about the universe at large.

The development of gravitational wave detectors has made it possible for astronomers to penetrate the deepest corners of the universe in search of black holes and neutron stars.

The contribution summarises the Beja lexicon connected with natural phenomena, including astronomical, temporal, and geographical terminology. Every lexeme is documented in available sources and etymologized in areal or genealogical perspectives. In the case of borrowings, the ambition is to trace primary donor-languages, usually Arabic or Ethio-Semitic, sometimes Nilo-Saharan. The inherited lexemes are identified, if no convincing donors were determined, while there are promising comparanda in other Cushitic, Omotic or other Afroasiatic branches.

Dmitriev-Mamonov is primarily known for his story that describes inhabitants of other planets. The story contains some controversial elements including an unflattering image of the clergy, heliocentrism, and the possibility of multiplicity of worlds. He also authored a Chronology and a free translation of part of the Psalter in which he included some of his theological views.

The article discusses the use of metaphors in the terminology of astronomy and astrophysics. The terminology of these fields is relatively stable, characterized by terminological diversity, thus allowing to draw sufficiently general conclusions. Three cases are to be considered: (a) first, the metaphor as a powerful source of terms, assuming the denominative function, (b) the terminological metaphor which leaves a certain domain and which penetrates into the general language, which is sometimes called determinologization, and, (c) finally, the terminological metaphor migrating from one specialized domain to other terminologies in which it is newly used to denote another concept, this phenomenon sometimes being referred to as transterminologization. The three processes are analysed and documented, using French and Czech examples, excerpted from specialised texts (encyclopaedic dictionary and newspaper articles).

The present paper examines the textual evidence, mainly the late Vedic codifications of the domestic rituals Gṛhya sūtras and Hindu religious and legal duties Dharma śāstras, related to the name giving tradition in ancient India. Issues are addressed: why according to tradition a brāhmaṇa should have two names, and why one of these names should be the nakṣatra (lunar constellation) name? How the secret ( guhya) stellar name was chosen? How name giving practices are related to the concept of the sacred speech in Indian religious culture? The historical and textual analysis of the Sanskrit sources, besides of the historical approach to religious studies shall be applied as the principal methodological tools. Conclusion is made that the Indian name derived from the nakṣatra was vitally connected with the of the individual and his super-personal power lying behind, and kept secret less enemies may do mischief to the man through it. The adoption of a second, secret name was assumed also for success and distinction in life.
