‘I enjoyed the scientific work, especially solving problems and understanding the physics of the stars, so doing something like this is a kind of motivation for other people to become interested in astronomy and until you studied physics and astronomy you don’t really know what is going on in the stars and you don’t see what professional astronomers are interested in. There are many things happening in our own galaxy and in our own solar system and of course with the space age we know a lot more now about planets and asteroids and many things. So even quite nearby objects turned out to be more interesting than people realised in the past. I studied the heat radiation from stars, with infra-red light. Usually stars that are forming or stars that are dying have a lot of dust around them and this shows up very strongly in the infra-red, so I studied basically variable stars that show up brightly in the infra-red and I studied certain types of galaxies which have active centers, the nuclei we call them - and Quasars. So you think of stars, but dust and gas are also very important parts of the galaxies in the sky.’

'Then you look at Saturn with the nice rings around it, it looks like a sombrero - that is just unbelievable. On the real astronomy side I’ve observed stars with are called roAp stars, it is short for Rapidly oscillating peculiar A stars. These are really peculiar. Those stars oscillate in a short time scale, like 8 minutes. What happens is the stars sort of blows up and gets bigger and fainter, then contracts and gets warmer. That is what you see. My first three years I was working with other people, as I was undergoing training. From there on most of the time I was on my own. Sometimes for 14 hours in winter, just with a CD player, my night lunch and my coffee. Then it is up to you to make all the decisions. You just got to make sure you stay awake and alert. Otherwise you can screw up big time. I did fall asleep, but the thing is, if you feel you are tired it is best to close the dome, switch everything off and sit and sleep. If you leave things on and you fall asleep then you are in trouble.’ - Francois van Wyk, Night Assistant and service observer, Sutherland.

'Are we alone, I don’t know - the thing is we will probably never know. If we find a civilization that can signal to us, we’ve got to be able to signal to them. If they are a 100 light years away we are talking about a 100 years between every communication, and by then the other one may have died out or they may have not reached the communications technology or we may have blown ourselves up enough to have to start all over again. So we will probably not communicate with anyone out there - not in our lifetime. But there is probably someone. We are so proud that we call them aliens - we may be the aliens. Who knows.'

‘That was the most beautiful to me, when there is a shooting star, I always believed you could make wish - for good luck. Then I asked some questions and they answered, ‘o, no - when there is a shooting star, it means it is dead and it is going to fall’ and there where it falls, everything must just pray and ask ‘God don’t let it fall on a house, don’t let it fall on a person’ - because it can burn and kill, and you don’t know if it has fire inside, you don’t know if it has hail inside or even iron inside.’
