All those nagging questions you have about the universe are answered here, like Is there a dark side to the Moon? What happens when a comet hits the sun? Do the Martian canals have any water in them? Is the moon hot inside? What would happen if the sun were to collide with a black hole? Mars has polar ice caps: could polar bears live on Mars? If I could go back to the time of the dinosaurs, would the sky look the same as it does today? and many more.

Lunatics. We have to realise that there may be unforeseen hazards which will put back these developments for many years. I have always believed radiation to be the most serious threat – there is no atmospheric shield on the Moon. Neither do we know the effects of living for a protracted period under conditions of one-sixth Earth gravity, and the problem may be unpleasantly obvious when the Moon-men return home, though of course it will be easy to make frequent journeys to and fro – something.

Of our rockets. We can reach the Moon and the planets, but we have absolutely no idea of how to cross interstellar space. Neither can we be one hundred per cent certain that other civilisations exist anywhere, though there are millions upon millions of other Solar Systems, and it seems both conceited and illogical to suggest that life is unique to Earth – the third planet in the family of a very ordinary star. If there are other races, they may differ from you and me both mentally and.

Important point must be remembered. It was put into orbit, from the Baikonur cosmodrome in what was then the Soviet Union, on 20 February 1986. It was scheduled to remain active for no more than five years. In fact it remained aloft for more than a decade and a half, and almost all the really serious problems occurred well after it had passed its original planned lifetime. For the first five years of the mission it achieved almost everything that had been expected of it. It had various.

Name – is visible with the naked eye for only a few weeks in every year. The story of its discovery is rather interesting. It begins in 1596 with the work of a Dutch amateur astronomer, Johann Fabricius, who noted an ordinary-looking star in the constellation of Cetus, the Whale. A few weeks later it had disappeared. It was seen again in 1603 by Johann Bayer, who was drawing up a new star catalogue in which he gave the stars in each constellation Greek letters, beginning with Alpha for the.

Will have exploded as a supernova. The ‘Summer Triangle’; Deneb, Vega and Altair But suppose it does have a planet, and that somehow or other we could pay it a visit? What would we see? In the daytime, Deneb would indeed be impressive, and probably very active. The night scene – that is to say, the view from the side of the planet turned away from Deneb – would be unfamiliar to us. Deneb is so far away, across the Galaxy, that we would see none of the constellations which grace our skies.
