Lightning on Venus

By SETH BORENSTEIN, AP Science Writer 1 hour, 40 minutes ago

WASHINGTON - Nearby Venus is looking a bit more Earth-like with frequent bursts of lightning confirmed by a new European space probe.

For nearly three decades, astronomers have said Venus probably had lightning — ever since a 1978 NASA probe showed signs of electrical activity in its atmosphere. But experts weren't sure because of signal interference.

Now a magnetic antenna on the European Space Agency's Venus Express probe proved that the lightning was real.

"We consider this to be the first definitive evidence of abundant lighting on Venus," David Grinspoon of the Denver Museum of Nature and Science told reporters Wednesday at a briefing in Paris.

The finding is significant because lightning affects atmospheric chemistry, so scientists will have to take it into account as they try to understand the atmosphere and climate of Venus, he said.

The lightning is cloud-to-cloud and about 35 miles above the surface, said University of California, Los Angeles geophysics professor C.T. Russell, lead author of a paper on the Venusian fireworks. It is being published in Thursday's issue of the journal Nature.

Bursts of electrical energy from lightning are something that scientists have long theorized could provide the spark of life in primordial ooze.

But not on Venus.

"If life was ever something serious to talk about on Venus, it would be early in its history, not in its current state," said Sean Solomon of the Carnegie Institution of Washington, who was not part of the research team. "It's a very unforgiving atmosphere."

The idea of Earth-like lightning is fascinating, Russell said. However, you couldn't see it from Venus' surface, nor would you want to look because the Venusian atmosphere is 100 times more dense than Earth's, is about 900 degrees hotter and has clouds of sulfuric acid, he said.

"It may be Earth's 'evil twin,' but it is in many respects Earth's twin," Russell said.

What excites astronomers most about the lightning discovery is simply the coolness factor.

Venus' weather forecasts have long thought to be "kind of boring ... steady winds for the next 400 years," said Allan Treiman, a senior scientist at the Lunar and Planetary Institute in Houston, who isn't affiliated with the research. The idea of lightning, he said, adds a spark to Venus' weather.

Well, I guess we'd better start putting lightening rods on probes then. Also, there is no standing under the Venusian trees.

Ugh. That guy just HAD to end the article with a (bad) pun, didn't he.

Good night, funny man, and thanks for the laughter.

Well, at least Doc Brown and

Well, at least Doc Brown and Marty McFly would always have a substitute for plutonium, if they ever went to Venus. Of course, they would be crushed under the atmospheric pressure, so it would probably be better, if they didn't.

Well, we all know what this means:

The real Mount Olympus is on Venus!

Well it is time to give up.

Well it is time to give up. Obviously, God is sick of humanity and has decided to start over from scratch. We have seven days before he obliterates us, you better enjoy it.

Hell no! It's on Mars. The most utterly vast mountain in the entire solar system, the gigantic and majestic Olympus Mons. Standing at 27,000 meters high, it is three times the height of Mount Everest, and spans a much vaster width (600 kilometers in summit span).

Even then, the thing looks like a little bumpy sand dune from space:

 

"Physical reality” isn’t some arbitrary demarcation. It is defined in terms of what we can systematically investigate, directly or not, by means of our senses. It is preposterous to assert that the process of systematic scientific reasoning arbitrarily excludes “non-physical explanations” because the very notion of “non-physical explanation” is contradictory.
