6. The High-Z SN Search Description
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. ...

12. Distortion during Expansion
The Hubble law produces a homologous expansion, which does not alter the shapes of patterns in the Universe. Other law such as a constant velocity (v = G*D 0 ) or a quadratic law (v = I*D 2 ) lead to a distortion of patterns. The picture above shows the result of expanding a familiar object by a factor of two using the constant velocity D 0 on the left, the linear Hubble D 1 law in the middle, and the quadratic D 2 law on the right. Tutorial: Part 1 | ... last modified 25-Aug-1997 ...

13. The Sun
The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...
