... Bad Astronomy . ... Bad Astronomy : The Moon appears larger on the horizon than overhead because you are comparing it to foreground objects. Good astronomy : The Moon does appear larger on the horizon, but it is because of the way we perceive the sky. ... The most common misconception is that it is because you are unconsciously comparing the Moon to foreground objects like trees and houses, or even the horizon itself, and that makes the Moon look bigger than when it is all alone in the sky. ...

Next: The Lynxx Tools Up: Data Processing Previous: Data Processing . Each program allows the operator to get a quick look at the data and do some processing. The ST-4 and ST-6 have the same basic tools, so only the ST-6 tools will be described here. Most of the tools are under the display menu. When an image is displayed in analysis mode, data can be roughly analyzed. Any process done under display will only alter the display and not the image itself. ...

... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...

... Astrophysics Group . ... MRAO Telescopes . AMI . ... This is a cosmic microwave background (CMB) telelescope with a difference, in that it is designed to survey the sky looking for galaxy clusters by means of the ?shadows? they cast against the CMB. This shadowing, the so-called SZ effect, is a remarkable phenomenon because it is independent of redshift, allowing AMI to find clusters which are so far away that their own emission would be too faint to detect ? ...

So the evidence for Dark Matter is fairly overwhelming. ... Theory: if the Universe is closed then all the luminous matter seen in galaxies contributes only 0.5% of the mass required to eventually halt the expansion . ...
