... What is the notion time? ... Generally speaking, it is an order of changing events, an order of constantly changing conditions of solids, Universe - being. ... The time, determined for the given longitude, is called the local time . ... A uniform system of time counting - ephemeris time is tested by observations of the Moon turning around the Earth. Fully independent from astronomic observation uniform system of the time counting is based on the concept of atomic second (see quantum watches ). ...

... Contacts . 2012: . ... We refined the fundamental parameters of the components, the orbital periods, and the conditions of photospheric heating of the secondary component by the ultraviolet radiation of the hot component. ... The observations of the star clusters associated with ultra-luminous x-ray sources (ULXs) in four galaxies on the 6-meter and VLT telescopes have shown that all the ULXs are located within 200pc of very young star clusters (younger than 5 million years). ...

... Iowa Robotic Telescope | ... Talon is based on OCAAS, a software suite developed by software engineer Elwood Downey ( Clear Sky Institute ) for use at the University of Iowa ?s first remote facility (the ATF, or Automated Telescope Facility). ... XObservatory : Telescope Control Interface . ... This program calls upon and coordinates much of the interrelated portions of the Talon architecture, and forms the primary control panel for the telescope, dome, and peripheral systems when used locally. ...

Application of IVOA software tools for radio sources investigation Zhelenkova O., Kopylov A., Chernenkov V. The interrelationship between the objects of astronomical catalogs in the different ranges of electromagnetic spectrum and their association into the real astrophysical source has obvious scientific interest. ... We used NVSS as the reference coordinate catalog. ... For 60% of radio sources identified with the objects of the radio catalogs we discovered optical candidates in SDSS survey. ...

... Planets . ... The planets were found using the HARPS instrument on the 3.6m telescope at ESOтАЩs La Silla Observatory. ... A planet in orbit around a star causes the star to regularly move towards and away from observers on Earth. ... One newly discovered planet, HD 85512 b, is best hope found so far for a habitable exoplanet. ... The HARPS team so far have found that about 40% of stars similar to own Sun have at least one planet smaller than Saturn (which is 95 times more massive than Earth). ...
