... Bad Astronomy . Misconceptions . ... The Nine Planets . ... This is true, and so I have updated this page with a tidal force calculation. ... That way we can see right away how strong the other planets are; a gravity of 10 means the planet pulls on the Earth 10 times as much as the Moon does. ... So, in units of Moon gravity and tides, below are the forces on the Earth from rest of the planets (the data for masses and distances are from the wonderful page The Nine Planets ). ... 2008 Phil Plait. ...

This page could be summarized with the statement: don't require Apache to use DNS for any parsing of the configuration files . ... In order for Apache to function properly it absolutely needs to have two pieces of information about each virtual host: the ServerName and at least one IP address that the server responds to. ... use IP addresses in Listen . ... In any event it doesn't seem possible to reliably boot a virtual-hosted web server when DNS has failed unless IP addresses are used. ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...

... 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). ...

... Scientists of Samara State Aerospace University (SSAU) have created an unique mobile platform for the production of training and gaming simulators. ... Such mobile platforms also known as the Stewart platforms became widespread in the world primarily as simulators for training of highly-qualified military pilots and drivers. ... For example, the Rocket and Space Centre Progress is going to test level sensors for residual fuel in the fuel tanks of the rocket carrier on this mobile platform. ...

Johann Kepler - a Legislator of the Sky. The laws of the planets movements put by Johann Kepler destroyed the thousand year old dogmas about the circles and spheres and opened the way to scientific understanding of celestial occurrences. ... The best object for observation was Mars - its orbit unlike the Earth's one has a noticeable eccentricity, the rotation period in comparison with Jupiter and Saturn is not too long and observation conditions are better than for Mercury and Venus. ...

... Introduction: E-, M- and S-type asteroids are widely considered as remnants of differentiated parent bodies; specifically, Ms might have been their cores [e. g., 1, 2]. The conviction is based on the visible-range albedo (medium to high) and overall spectral curves (slightly reddish to red) of the small planets corresponding to these of metal iron and igneous silicate assemblages. ... It seems the spectral features superimpose to the spectral characteristics of metal iron and igneous silicates. ...

The program of deployment of small orbital station (SOS) consisting of a family of spacecrafts and module-spacecrafts represents a consecutive realization of flight scenarios with consecutive building up of functions. ... Scenario 1 - the regular and revised spacecrafts of class "Soyuz" - TMSC and MNMSC (MNMSC-cargo, MNMSC-MR) are used, pls. see fig fig.8 . ... The terms of transition to this scenario are determined by terms of readiness of one or another module....

... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...
