Venus, not Mars had conditions more suitable for life, reveals study

The cloud-shrouded planet most likely started with oceans much like Earth’s, which evaporated as Venus heated up, David Grinspoon from the museum said at a meeting of planetary scientists at Orlando, Florida.

Grinspoon said preliminary results of new computer models had shown that Venus might have retained its oceans for a billion years after it formed, possibly longer.

The oceans didn’t disappear overnight, the National Geographic quoted Grinspoon as saying.

Incidentally, prior models had indicated that rising Venusian temperatures turned the oceans to steam within the planet’s first 600 million years.

Grinspoon said the extra 400 million years were even more significant than they sounded, because early Venus was constantly under bombardment of asteroids, reducing the likelihood of life.

He said the new finding suggested that the oceans existed for much longer after the asteroid bombardment tapered off.

“There may have been a sizeable interval when [Venus] was habitable. Today, however, Venus is about 100,000 times drier than Earth and is 860
