... Bad Astronomy . Misconceptions . ... Bad Astronomy : The Moon only shows one face to us because it is not rotating. Better astronomy : The Moon only shows one face because it is rotating, once every time it revolves around the Earth. ... Place the Moon model on the table about 30 centimeters (one foot) away with the X facing the Earth model. ... You'll see that to keep the X facing the Earth model, you have to rotate the Moon model as it goes around the Earth model . ... 2008 Phil Plait. ...

To have a census of the old stellar populations of the dwarf irregular galaxies NGC 1569 and NGC 1705 and to trace the major episodes of star formation over a Hubble time in these starbursting systems, we have applied for and obtained HST/NICMOS observations in the F110W and F160W bands with the NIC2 camera. ...

... SCIENCE RESEARCH ON ISS RUSSIAN SEGMENT . ... On 28 January 2005 the russian Federal Space Agency, S.P. Korolev Rocket and Space Corporation Energia and European Space Agency (ESA) concluded a Contract for a mission of the Italian Astronaut, Roberto Vittori, member of the European astronaut corps as Soyuz TMA-6 Flight Engineer and the visiting crew VC-8 (April 2005, ISS-10, ISS-11) to the International Space Station and performance of ENEIDE ISM (ESA) Project science research and experiments. ...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... 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...

... Description . Catalog . ... In the Catalog, we publish equatorial (ЮБ 2000 , ЮД 2000 ) and galactic (l,b) coordinates of cluster centers derived as the position of overdensity in 2MASS catalog (Koposov et al. ... Distances, color-excesses and ages are the mean-square values calculated using all available evaluations from different color-magnitude diagrams. ... There are individual pages for every cluster where all available plots and parameters are published. ... 2002). ...

... 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: . ...

Detection of the YORP Effect from Photometric Observations of Near-Earth Asteroids . ... In this report we present summary of photometric observations of near-Earth asteroids (NEAs) obtained to search for YORP effect. ... Observations of 1620 Geographos in 2008 and 3103 Eger in 2009 are used to detect the acceleration of the asteroids rotation rates in agreement with the computed theoretical values due to YORP effect. Now there are four asteroids with the YORP effect detected. ...
