The craters and mountains of the moon, the rings of Saturn and the moons and belts of Jupiter can easily be seen with a simple, inexpensive telescope of your own making. Making a telescope does not need to be an expensive or time-consuming project, although if you are interested in making serious scientific observations, then, of course, it is better to build a more costly reflecting telescope.

BLACK HOLES: A MYSTERY OF THE UNIVERSE

By K.E. Chilton
93 Currie St.,
Hamilton, Ont.

Black holes! The very name conjures up a mystery! What is at the bottom of the hole? What causes a black hole ? What would happen if you fell into one? These questions and others provide one of the greatest mysteries of our Universe, one which has attracted much space in the newspapers, and one which has caused much discussion among astronomers.

Is the Moon a cold, lifeless, changeless body? Or, are there changes from time to time? Recently, there has been much interest in amateur astronomical circles, in investigating changes on the Moon which seem to be of a transitory or impermanent nature.

This was written to augment a talk by Robert G. Speck to the Discussion Group of the Hamilton Centre of the Royal Astronomical Society of Canada on April 22, 1976.

PRE-MARINER FINDINGS

Three main cloud types have been distinguished in the thin, dry, cold Martian atmosphere: white, blue and yellow clouds, so named for the colours which they predominantly reflect.

White Clouds:

White clouds vary considerably in thickness, brilliance and extent. They can be subdivided into three categories:

For several years, the author has corresponded with Prof. J.M.L. da Silva of the State College of Parana, Curitiba, Brazil, about the variable star RX Lepporis. We agreed that certain of our visual observations were in doubt because of certain irregularities in the published magnitude sequence for stars on the comparison chart, AAVSO chart 050001 W Ori.

THE OLDEST AMERICAN OBSERVATORY?

By
K.E. Chilton

In 1971, the planet Mars will attract considerable attention, from laymen and from astronomers. For, this is the year in which Mars reaches its minimum distance from the Earth, some 35 million miles on August 10. No doubt, the press will publish a full quota of stories about canals, life on Mars, and whether or not the two moons of Mars are, in fact, satellites put into orbit by a long vanished race. There will invariably be the usual rash of flying saucer tales as is customary in years of close approach.
