... Under conditions of the Earth gravitation we are using the method of semi-natural simulation of linear accelerations in the centrifuges with a mobile cab for simulation of G-loads, originating in a space flight. ... The major factor of the orbital flight, affecting a cosmonaut, is a weightlessness state, which causes essential changes in cardiovascular and vestibular systems operation. ... Under the Earth conditions you can "execute" a short-term space flight according to the following cyclogram: . ...

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. ...

... Planets . ... Earth Satellites . ... 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. ...

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

... Tutorial : Part 1 | ... Until a few hundred years ago, the Solar System and the Universe were equivalent in the minds of scientists, so the discovery that the Earth is not the center of the Solar System was an important step in the development of cosmology. ... In 1929 Hubble published a claim that the radial velocities of galaxies are proportional to their distance. ... The slope of the fitted line is 464 km/sec/Mpc, and is now known as the Hubble constant, H o . ... Ned Wright's Home Page . ...

... Like a last gasp of breath, Sun-like stars puff away their outer layers of gas at the end of their lives. This gas floats away into space and forms beautiful and striking clouds, which are called planetary nebulae (although they have nothing to do with planets). ... Yet, astronomers looking at 100 planetary nebulae in the bulging centre of our Galaxy, the Milky Way have found that most of the bipolar planetary nebulae in this region are acting in the same, strange, way. ...

... 1 Star Mapp ers You are a group of amateur astronomers, and you've spent the last ten years mapping the sky, drawing beautiful charts of everything you can see with the naked eye. ... Rather different is the famous, and unexplained "Milky Braid", a band of diffuse white light that crosses the sky. ... At any given time, from and particular point on Klovia, you can only see half of it, but the full braid goes all the way, 360 degrees, around the sky. ... Let's say you see a dot of light. ...

Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...
