... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

Allows you to specify a drift scan: motion at a constant velocity along a great circle. ... The path starts at the new object position (though the telescope actually intersects the path later, see Subtleties ). ... Note that the units are always /sec for both axes. ... The velocity along the path is 0.01 /sec. ... The path is assumed to start when you hit the Slew button (more precisely, when the TCC parses the command). However, it takes the telescope awhile to slew to meet the specified path. ...

The Doppler shift is the effect of sound increasing or decreasing in pitch as an object moves towards or away from you. ... Light works the same way, except light is shifted to redder colours when an object is moving away, and to blue colours when an object is travelling towards us. ... Almost every object he observed had its light stretched to redder colours, indicating essentially everything in the Universe was moving away from us. ... So the Hubble constant tells us how old the Universe is. ...

... Energy Levels . ... Radiation from . Hot Objects . ... Instead he wanted to explain the continuous spectrum emitted by hot solids--also known as " black body spectrum " because it is supposedly emitted by an ideal hot object ("black body") whose structure gives no special preference to any color (as happens with green grass, blue jeans and red bricks). ... A "black body spectrum" is also expected in light from hot dense gases, where strong energy exchange exists among frequently colliding atoms. ...

... Bad Astronomy . ... Mad Science . ... Ignoring the factor of gravity from other objects, if two extremely massive objects (with the mass of the sun or greater) were moving towards each other at nearly the speed of light, wouldn't their gravities cause them to accellerate to beyond the speed of light before they collided? ... So what this is saying is that as you get very close to the speed of the light, the denominator "blows up" and the energy needed to get to the speed increases very rapidly. ...
