Astronomy, Astrophysics & Space Physics in Greece
In the present document I review the current organizational structure of Astronomy, Astrophysics and Space Physics in Greece. I briefly present the institutions where professional astronomers are pursuing research, along with some notes of their history, as well as the major astronomical facilities currently available within Greece. I touch upon topics related to graduate studies in Greece and ...

متن کاملExploring the Universe: Space-Based Astronomy and Astrophysics
For millennia until the Second World War, astronomical observations were limited to visible light, the type of electromagnetic radiation sensed by the human eye. When people look at the sky with the naked eye, they see only stars and patches of dark against dense star backgrounds, as in the southern Milky Way. With a telescope, one can see nebulae, or clouds of gas, shining either by fluorescen...
متن کاملAstronomy and Astrophysics Orbit Determination for next Generation Space Clocks
In this paper, we study the requirements on orbit determination compatible with operation of next generation space clocks at their expected uncertainty. Using the ACES (Atomic Clock Ensemble in Space) mission as an example, we develop a relativistic model for time and frequency transfer to investigate the effects of orbit determination errors. We show that, for the considered orbit error models...
متن کاملIntroduction. Progress in astronomy: from gravitational waves to space weather.
This brief paper introduces and reviews the 'visions of the future' articles prepared by leading young scientists throughout the world for the first of two Christmas 2008 Triennial issues of Phil. Trans. R. Soc. A, devoted, respectively, to astronomy and Earth science. Contributions in astronomy include the very topical gamma-ray bursts, new ideas on stellar collapse and the unusual atmospheres...
