Experts Puzzled By Bright Spot On Venus 107

Hugh Pickens writes "BBC reports that astronomers are puzzled by a strange bright spot which has appeared in the clouds of Venus, first identified by US amateur astronomer Frank Melillo on 19 July and later confirmed by the European Space Agency's Venus Express spacecraft. 'I have seen bright spots before but this one is an exceptionally bright and quite intense area,' says Melillo. The bright spot has started to expand since its first appearance, being spread by winds in Venus' thick atmosphere. Scientists are unsure as to what is causing the spot. 'An eruption would have to be quite energetic to get a cloud this high,' said Dr. Sanjay Limaye of the University of Wisconsin. Furthermore, at a latitude of 50 degrees south, the spot lies outside the region of known volcanoes on Venus. Another potential source for the bright spot are charged particles from the Sun interacting with Venus' atmosphere. It's also possible that atmospheric turbulence may have caused bright material to become concentrated in one area. 'Right now, I think it's anybody's guess,' adds Limaye."

Comment It has always been the case (Score 1) 135

Let us remember that the entire world was created from microscopic life forms, not by computers. The life forms learned from the environment and evolved in ways which even the most sophisticated computer would have an impossible time understanding. Let us remember that computers are, by a long shot, not the most efficient problem solvers. For instance, no computer can recognize patterns as well as a human being. The control system governing a hummingbird flight is way more advanced than that of the greatest and mightiest fighter airplane.

Computers are not problem solvers - they merely automate repetitive procedures or, at best, algorithmically apply a set of rules to a given problem -- Nature has always been more potent than computers.

I am impressed they can solve a simple problem with bacteria though. Maybe I should stop brushing my teeth and let the bacteria in my mouth say something intelligent.

Peace.

Comment NASA's credibility (Score 1) 222

As an Space Program advocate, I certainly hope they find them-- the public needs to trust NASA again; knowing that NASA can keep track of its mission assets would be the very basic start.

Whoever found the tapes (if they really were found) should not feel disappointed about not breaking the news him or herself. It is a shame they were lost in the first place, and finding them is nothing to feel proud about. I cannot imagine loosing my baby in the supermarket and then feeling like a real smart, witty person for finding her two years later.

We should avoid the "butterfly effects" of the proposed solutions. We don't know what will happen if we just dump shit in the ocean, it might be that the remedy is worse than the disease.

For the plant argument, I agree we cannot just plant whatever ficus we happen to like. However, planting trees of the same species we've cut in the same places where we've cut them would be a start-- they were already there, and nothing bad happened to us.
