Looking in the direction of the constellation Cygnus the Swan and launched by NASA in 2009 is the Kepler Space Observatory.Many previous missions searching for exoplanets mainly detected large giant planets, like large hot Jupiters (it is easier to detect larger planets).However KeplerтАЩs main objective is to search for much smaller planets located in a habitable zone which is not too close nor too far from their star; planets which may be just like our Earth. ...

In ancient times the solar system was thought to be the whole Universe, so the study of planetary motions was cosmology. ... The planets other than the Moon and Sun generally move West to East through the stars, but occasionally stop and move in the opposite direction ( retrograde motion). In order to explain the retrograde motion of the planets, the geocentric model of the Solar System shown above puts the planets on small circles called epicycles . ...

... We still have a long distance to cover before we leave the Milky Way Galaxy -- tens of thousands of lightyears, as a matter of fact -- so let's stop by some interesting objects on the way. ... But we have reached the edge of the Milky Way Galaxy. ... We don't know, but we do know that there are countless voyages left to take.

... part 2 | ... Part 1 . The new concept of formation and development of the Solar system. ... Thus, the initial pulse of the rotation of a protosolar cloud of the solar system was determined as a result of the diversion of a part of the moment of the rotational pulse of the Galaxy. ... Besides this new approach to the pre-solar system as a system of the destroyed vortex structure, we can understand now a number of other peculiarities of the Solar system's structure. ...

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
