Like Mercury, Venus suffers from many strange polar phenomenon. Take a look at the drawing below done in 1891. It shows Venusian "polar caps"
(Click on the image to enlarge it).

Venus is of course far too hot to actually have ice in its polar regions. Furthermore, Venus has a very thick atmosphere and thus we cannot see its surface. The "polar caps" are therefore an atmospheric phenomenon occurring high in its polar regions. But what causes it? Scientists have said that sulphuric acid droplets high in the polar atmosphere causes this abnormal brightness. These droplets are highly reflective and this is why the polar regions can be brighter than the lower latitudes.

There is however a problem with this explanation. Take a look at the drawing above again and notice how the polar caps actually extend into the night side of Venus. No matter how reflective the high atmosphere is, it is impossible for the night side of the planet to be lit by direct light from the Sun. It seems to me as if Venus has a luminosity of its own, as incredible as that may seem.

Other drawings done by astronomers over the years show that sometimes the polar regions disappear - just like they do on Mercury. Various streaks have been observed emanating from the polar regions, as if air currents are emanating from the poles - from Polar Holes perhaps?

On the 29^th of March 1873, W. F. Denning observed a depression in the polar regions which he described as looking like a "small crater". Did Denning see a phenomenon caused by a Polar Hole? Was he watching Venus "breathing"? In the early 1970's this depression was seen again by a number of British and American astronomers.

Another phenomena seen and even photographed by NASA space craft, is the polar "collar". This is a ring which surrounds the polar regions. Could this ring be linked to the existence of Polar Holes on Venus?

There are some astronomers who suggested that the strange brightness features of the Venusian poles may be caused by some type of auroral activity in its polar regions.

But the strangest sighting of Venus ever made was that by the very famous and respected German astronomer, Maedler in the 1800's. He once observed Venus as looking like a comet! His drawing of Venus showed two beams of light emanating from both its polar regions. These beams of light were pointed towards the Sun, and gave Venus the appearance of a comet with two tails! At the time Maedler conducted several tests by changing eye-pieces, and moving his telescope to ensure that what he was seeing was real. It remains to this day the strangest sighting ever made of this planet.

Even NASA photographs which I obtained show the abnormal brightness of Venus's polar regions on occasions - with the polar regions in one instance being 60% brighter than the equator.

It seems to me, from my studies, as if Venus actually has gigantic Polar Holes. The bizarre lighting phenomena seen by Maedler along with the drawings of polar caps suggests that there is some type of light shining out of this planet. Could this be caused by a mysterious Inner Sun existing inside a hollow cavity inside the planet? Could this also explain the strange weather and lighting phenomenon seen whereby the polar caps are lit abnormally even into the night side of the planet? And would a rising and falling atmosphere be the cause of the crater-like depression seen on occasion by astronomers?

Strangely, NASA photographs show none of these phenomenon. Could it be that NASA is hiding something from us?
