11、er of comets are found by comet hunters carrying out telescope searches of chosen areas of the night sky.As the movement of all comets is directed around the Sun and because these bodies brighten as they move towards the Sun,there is a greater possibility for the discovery of a new comet in the skie

12、s towards the Sun rather than away from the Suns direction.This means that searches should be put on the western sky after evening light and on the eastern sky before morning light.From the astronomical point there is no time during the year which is the best for the discovery of new comets.A search

13、 can be done at any time providing there is no bright Moon.Studies done on the discovery conditions of comets discovered before show that more comets have been discovered in the morning sky than in the evening sky.Thus the smart comet hunter should make sure that morning activity receives as much if

14、 not more attention than any evening effort.In recent times,the use of advanced CCD technology to discover objects close to the Earth will in the future greatly reduce the chances of new comets being found with small telescopes.An example of the new technology is the very successful LINEAR program o

23、tings looked so real that some people thought they were photographs.Even though Bonestell was interested in astronomy,he did not start out as a space artist.As a young man he studied architecture the art and science of designing and making buildings.In 1938 Bonestell became a special effects artist

24、in Hollywood.It was here that he learned he could improve his paintings by following the methods used in the movies.In 1944,a popular magazine published a series of Bonestells paintings of the planet Saturn.He drew Saturn as if it were seen by someone standing on each of the planets moons.The result

25、s were dazzling.Within a few years,Bonestells artwork was appearing regularly in magazines and books on astronomy and space flight.Many of Bonestells artworks had been right all along.But the biggest surprise was the Moon.Someone asked Bonestell what he was thinking when he saw the first pictures fr
