NASA Found Evidence That Life on Venus Might Have Existed In The Past

It is currently being theorized that life on Venus could have existed a long time ago. NASA has made the discovery that the planet had many similarities to Earth. Because of similar dimensions and bulk compositions, Venus is often referred to as being related to Earth.

But on closer inspection, Venus has an atmospheric pressure that is similar to that of the ocean at 1 km in depth, that is by 92 times greater than the pressure on the surface of the Earth. The temperatures on Venus are no joke either, being the hottest planet in the solar system, at 500 degrees Celsius. And that’s even hotter than Mercury, the closest planet to the Sun.

Scientists think that life on Venus might have existed in the past

The story behind the evolution of Venus is linked to that of the Sun as age dictates how hot a star gets. A cooler star means a cooler orbiting planet. That’s something evidenced by the remnants of flowing water within the surface of Venus. It is believed that Venus found itself cooling as to allow for the formation of water, just a couple million years after it had formed. And that might mean that life on Venus could have flourished in the past.

While finding itself under similar conditions, relative to Earth, it is not a certitude that Venus was affected much in the same way as Earth to allow for the creation of flora and fauna. How this works is that a planet needs to have an atmosphere to enable the formation of clouds to produce water, thus creating a greenhouse effect under the right conditions. However, life on Venus could have been possible.

Now, there are better candidates for life formation, and Titan is one of them

Titan, a moon of Saturn, is considered a candidate for future maintenance of life. The Cassini satellite offered significant data while maintaining its orbit around Saturn for a year. NASA observed great bodies of liquid methane in the north pole of the moon.

“What is also fascinating, and, in fact, tantalizing, is that Titan has complex chemistry and that chemistry is carbon chemistry – the chemistry of life,” Doctor Brian Cox comments. “So we have found molecules like hydrogen cyanide, which is the building block of amino acids, we found molecules called vinyl cyanide, which chemists and biologists speculate could form some sort of cell membranes,” Cox added.

A series of discoveries within our solar system has allowed for the certainty of past and future creation of life under the right circumstances. As we found out, everything in space is always moving, always changing for the better or the worse when the creation or destruction of life is concerned. And, under these arguments, life on Venus might have existed in the past.
