Years ago, I remember watching an anime film about humans leaving #Mars and coming to #Earth. I always thought we came from #Venus, and if it weren't for the acidic atmosphere, we would find a bunch of cars there, stuck in a traffic jam on the surface.

NASA Climate Modeling Suggests #Venus May Have Been Habitable
by Rob Garner
Aug 11, 2016"Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history, according to computer modeling of the planet’s ancient climate by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.
"The findings, published this week in the journal Geophysical Research Letters, were obtained with a model similar to the type used to predict future #ClimateChange on Earth.
"'Many of the same tools we use to model climate change on Earth can be adapted to study climates on other planets, both past and present,' said Michael Way, a researcher at GISS and the paper’s lead author. 'These results show ancient Venus may have been a very different place than it is today.'
"Venus today is a hellish world. It has a crushing carbon dioxide atmosphere 90 times as thick as Earth’s. There is almost no water vapor. Temperatures reach 864 degrees Fahrenheit (462 degrees Celsius) at its surface.
"Scientists long have theorized that Venus formed out of ingredients similar to Earth’s, but followed a different evolutionary path. Measurements by NASA’s Pioneer mission to Venus in the 1980s first suggested Venus originally may have had an ocean. However, Venus is closer to the sun than Earth and receives far more sunlight. As a result, the planet’s early ocean evaporated, water-vapor molecules were broken apart by ultraviolet radiation, and hydrogen escaped to space. With no water left on the surface, #CarbonDioxide built up in the atmosphere, leading to a so-called runaway #GreenhouseEffect that created present conditions."

Imagine if 170mph winds become the norm. Not very habitable, eh? (For comparison, Venus has 180-250mph winds)
More than 100 tornadoes, including an EF4, struck the nation's heartland
Multiple towns in the center of the nation were devastated by powerful tornadoes with winds to 170 mph last weekend.

Subsurface Oceans Could Boost Exoplanet Habitability
Researchers have shown that oceans buried below layers of ice are more common than previously thought.
If true, this would imply in the galaxy aquatic icy moon life will outnumber air-breathing Earth-like life by about four-to-one.

In the search for life on other Earths, astrobiologists should look for signs of photosynthesis, say scientists.
