An intense bright spot has appeared in the clouds of Venus. Could it be associated with volcanic activity on the surface?
The Solar System is breaking out in spots. First Jupiter took a smack from a passing asteroid or comet, manifesting as a dark scar in the Jovian atmosphere, and now Venus is sporting a brilliant white spot in its southern polar region.
In an alert to fellow amateur astronomers, Venus observer Frank Melillo reports on his images captured on 19 July: "I have seen bright spots before but this one is an exceptional bright and quite intense area."
Back in 1996, astronomers discovered a strange object in the asteroid belt. They decided it was either a "lost" comet or an icy asteroid, as it ejected dust like a comet but had an orbit like an asteroid. No one had ever seen anything like the object, called 133P. Ever since it was found, astronomers have wondered if it was just an oddity — one of a kind. We now know it is not, and the discovery of more of these half asteroids/half comets means there is a new class of objects in our solar system.

So het Jupiter Sondagaand net na 23:00 gelyk. Links onder is 45 Cap in Capricornus wat gesorg het dat daar nog `n "maan" sigbaar was.
Tot die 5de Auguatus gaan hierdie formasie weer sigbaar wees.
(Die voorstelling is met Skytools 3 voorberei.)
