In order to be able to burst through the gravity of the Earth, a rocket needs to travel at a speed of 25,000 miles per hour. Now, we’re not scientists ourselves, but it seems like that’s pretty fast.

From space, you can see quite clearly the division between East and West Germany. This is since the different regions use different types of lightbulbs. Hence, the type of light produced is noticeably different.

Why aren’t there any green stars?

There are no green stars because the ‘black-body spectrum’ of stars, which describes the amount of light at each wavelength and depends on temperature, doesn’t produce the same spectrum of colours as, for example, a rainbow. A star whose peak light emission is at a wavelength we might call ‘green’ actually produces almost as much red light, and our eyes interpret this combination as white, not green. For our eyes to see it as green, a star would have to emit only green light, which is not possible.
