... 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...

RESEARCH OF EQUILIBRIUM STATE OF SPACE TETHER SSTEM CONSIDERING ATMOSPHERIC D RAG D , L A, Cq N P U The equilibrium equations of tether and subsatellite will be given with the consideration of tether mass, tether deformation and atmospheric drag. Space tether system equilibrium state will be obtained through solving the equilibrium equations of tether and subsatellite. ... Space tether system equilibrium state is obtained by calculating Tether and payload equilibrium state equations. ...

A giant wave of gas crashes onto a dense ripple in this computer-simulated view of the solar nebula from which the Sun and planets formed. This is a side view of the disk, where whiter colors represent gas of higher density. ... The gas is thrown upward as it runs into a dense spiral ripple in the nebula, then curls over like a breaking wave and crashes back onto the disk. ... As the wave breaks, it forms a tube of low-density gas nearly 8 million miles (13 million kilometers) wide. ...

... It appears from qualitative considerations that when the mean free electron path I is sufficiently long, then for the field Hs, in which electron trajectories lying in the extremal cross section of the Fermi surface fit exactly within the plate, touching both surfaces, the magnetic-field dependence of impedance should exhibit a-3ingularity. ...

... This year's most powerful solar flare was photographed by TESIS telescopes in the southern hemisphere of the Sun on July 5th, 2009. ... Events of such power are unique and are only observed during maximal solar activity. ... For two months, all the activity of the new solar cycle was connected with areas of this belt, including the first solar flares and coronal mass ejections of the year. ... Nevertheless, this year's largest solar flare occurred in the southern belt. ...

ATMoB "Double Star Award " Guidelines Purpose: To promote observing among the membership of the Amateur Telescope Makers of Boston ­ in particular, double, triple, and multiple stars. Introduction: Double, triple, and multiple stars are the "Rodney Dangerfields" of the night sky. ... W hile they can be observed under a variety of sky conditions, double stars ­ especially close ones ­ are best viewed on nights when the seeing is steady. ... The direction from a star to Polaris is north. ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

... Oleg V. Verkhodanov . ... The last few years have changed our view on the evolution of galaxies: the most distant galaxies (i.e. systems having stellar population) have been found at redshift z=6.68 (Chen H.-W., Lanzetta, K. M., Pascarelle, S. 1999, Nature, 398 , 586) and radio galaxy at z=5.19 (van Breugel W., De Breuck C., Stanford S. A., Stern D., Rottgering H., Miley G. 1999. astro-ph/9904272 ). ... Redshifts and age of stellar systems of distant radio galaxies from multicolour photometry data. ...

. Comment on J1239-1023 . No image is shown by Dallacasa et al. (1998) as they did not find the VLBI structure at 2.3 and 8.4 GHz prominent, just dominated by a compact region barely resolved in position angle about -45 . In our case the source is well resolved, with a jet pointing to the W-NW direction, in agreement with what is seen in the images at 2.3 and 8.4 GHz from the VLBA Calibrators database.
