The murmering and chuckling displays delight, comfort and contemplative joy at what will be seen in the sky tonight. Bursts of joyous laughter bring one back to the chatter and fun of the evening. Do join ASSA JHB on the hill for a lovely evening of sky and braai. Dress warmly, bring along your meat to braai, your condiments, drinks and salads, anything you need for your meal, hmm… fingers were invented before knives and forks? and  oops, do not forget a chair or ‘situpon’. You may bring your own telescope if you want to.

In the Night Sky

NIGHTS IN THE MONTH OF MAY

 

In the Northern Hemisphere the month of May is usually termed the Merry Month of May.

Astronomers who practice visual astronomy in the Southern Hemisphere, feel that way too.

We have constellation Scorpius and  Planet Jupiter and not to mention in crispy dawn we have Mars and Saturn in our skies to view.

Astronomy is going ahead in leaps and bounds. Scientists are finding so much new stuff while we revel in the beauty of the known.

Canopus this month has lots to read, lots to ponder over and discuss. Do not miss out, read all about it.
