... between them is of no consequence to day-to-day observations. We therefore imagine the stars to remain fixed on a sphere of very large radius with the earth at its centre. We call this sphere the celestial sphere. At any point of time we can only see the upper half of the celestial sphere. The point ...

... It is tricky to explain the reason why the atmospheres of stars “boil” outwards – and cool off in the process to a “red” or at least “orange” color – as the star gets brighter. Let me put it this way. If the atmosphere of the star was perfectly transparent, then it would not boil outwards. The extra ...
