Or is it?
"Coulds of Venus crackle with lightning, scientists say" by Seth Borenstein/Associated Press
November 28, 2007
Venus, the closest planet to Earth in distance and in size, was at one time similar in climate to Earth and today has frequent bursts of lightning, scientist said yesterday. Based on evidence from the European Space Agency's Venus Express mission, the scientists said, the two planets started out as virtual twins.
But at some point in their 4.5-billion-year histories, Venus's proximity to the sun transformed its life-giving water into atmospheric vapor and turned the planet into a hellish kiln -- its surface hot and dry and its crushing atmosphere made up of carbon dioxide permeated by clouds of sulfuric acid that cloak the planet.
So the sun cause climate change and global warming, huh?
I was told it was humans!
Scientists have long theorized could provide the spark of life in primordial ooze. But not on Venus.
Sean Solomon of the Carnegie Institution of Washington, who was not part of the research team:
"If life was ever something serious to talk about on Venus, it would be early in its history, not in its current state," said "It's a very unforgiving atmosphere."
Too bad! I was looking for a place to move.
"New Findings Underscore an Earth-Venus Kinship" by KENNETH CHANG
Other than the hellish heat, a crushing carbon dioxide atmosphere and corrosive clouds of sulfuric acid, Venus is a lot like Earth, scientists said yesterday.
In a news conference at the Paris headquarters of the European Space Agency, the scientists, working on the agency’s Venus Express mission, played up the Venus-as-Earth’s-twin angle in presenting their newest findings, including signs of lightning, surprising swings of temperature and additional evidence that Venus could have once had oceans the size of Earth’s.
Dmitri Titov, the mission’s science coordinator:
“They’re really twins which are just separated at birth. The key question is why those twins are so different.”
Understanding the dynamics and history of Venus’s turbulent atmosphere could lead to a better understanding of the role that heat-trapping gases like carbon dioxide play in shaping the climate of planets including Earth.
Venus is about the same size and mass as Earth, and of roughly the same composition. And before the space age, planetary scientists imagined an Earth-like environment, perhaps even tropical jungles, obscured by Venus’s perpetual cloud cover.
Yeah, remember when you "space aliens" were martians and venitians?
Old twilight zone episodes.
Visits by spacecraft confirmed that the surface temperatures exceed 800 degrees Fahrenheit, hot enough to melt tin and lead.
But not WTC steel, right?
Although Venus is closer to the Sun than is Earth, the clouds reflect much of the sunlight, and the high temperatures largely result from the heat-trapping effects of an atmosphere that is almost pure carbon dioxide and about 100 times as dense as Earth’s.
Scientists imagine that Venus formed with much liquid water, just like Earth, but that because it is closer to the Sun, with sunlight twice as intense as on Earth, the water began to evaporate. Water vapor, also a greenhouse gas, trapped heat.
So the sun getting hotter could be the cause!
David Grinspoon of the Denver Museum of Nature & Science:
“That heats up the surface and leads to more evaporation. It’s a powerful feedback.”
The evaporation accelerated until all the liquid water had turned into a thick atmosphere of water vapor. As the water molecules floated in the air, scientists hypothesize, ultraviolet rays from the Sun broke them apart into hydrogen and oxygen atoms. Chemical reactions with minerals in the rocks transformed the oxygen into carbon dioxide. The hydrogen, the lightest of atoms, escaped into outer space.
That sounds strange; however, I'm a historian, not a scientist!
Measurements from Venus Express, which arrived at the planet last year, support that hypothesis, looking at amounts of hydrogen remaining in the atmosphere compared with concentrations of deuterium, a heavier version of hydrogen. The heavier deuterium would escape more slowly into space, and Venus Express detected a deuterium-to-hydrogen ratio 150 times as high as on Earth, a finding that agreed with earlier measurements. What was surprising, though, was that the deuterium concentration turned out to be 2.5 times as high in the upper atmosphere as near the ground.
Dr. Grinspoon: “We haven’t completely figured out what it means yet. Once we crack this mystery, this will be an important clue to this overall question of the history of water.”
In other measurements, Venus Express detected the bursts of radio waves known as “whistlers,” which, at least on Earth, are generated by lightning, and also found large temperature swings, up to 70 degrees Fahrenheit, between the daytime and nighttime sides of Venus.
The much thicker atmosphere would have been expected to minimize the temperature differences, said Andrew P. Ingersoll, a professor of planetary science at the California Institute of Technology who wrote a commentary in Nature to accompany the scientific papers.
Dr. Ingersoll said he remained skeptical of lightning despite earlier observations by space probes and Earth telescopes. The clouds of Venus are much different from those that produce thunderstorms on Earth.
Dr. Ingersoll: “They’re more like smog in L.A. It’s really just a haze of sulfuric acid. That kind of cloud, at least on Earth, doesn’t produce electrical charge. And thus it’s a little puzzling to have lightning.”
Can't the MSM get anything right?
So is there lightning or isn't there?
And if they don't know, why are they trying to tell us there is?
Is this just to push that globalist environmental agenda again, MSM?
