As the second planet of the Sun, because of its similar size, mass, and mass, Venus is often referred to as Earth's "sister planet." Although similar from afar, the close up case could not be more different. The atmospheric pressure on the planet is 92 times that of the Earth or about 900 meters below our surface.
Venus is by far the hottest planet in the solar system, with an average surface temperature of 500C, although mercury is closer to the Sun.
After the birth of the solar system, things could not have looked different, as Brian Cox revealed in his new BBC series. " The planets.
He said in May: "The surface temperatures on Venus are hotter today than on Mercury.
Planet, the sun itself has evolved.
Venus had flowing rivers in his distant past
Brian Cox unveiled the NASA find
Rivers of water flowed and Venus became an ocean world
"As the sun ages, the star always burns hotter and hotter.
"That means that in the past, when the sun was younger, the sun needed to have been cooler and that had a big impact on the planets."
Dr. Cox went on, revealing how cooler and wetter the Venus was with all the proper features to support life.
He added, "By the time Earth's life just started, three and a half to four billion years ago, the sun was weaker and that meant Venus was cooler.
"In fact, the temperatures on Venus at that time would have been like a pleasant spring day here on Earth.
"Joke After a few million years of its formation, the surface of Venus had cooled and the planet was just at the right distance from the faint young sun so that Venus could experience a familiar sight here on Earth.
"The sky opened and great streams flooded the surface, streams of water flowed and Venus became an ocean world.
"The atmosphere of the planet allowed him to keep the oceans as a blanket and to keep the surface temperate thanks to the greenhouse effect."
Dr. Cox also revealed in the same series how alien life could thrive on Saturn's moon Titan in the future.
He stated, "The Cassini [satellite] was still in orbit around Saturn and flew high above the Titan's North Pole a year after Huygens landed and discovered something nowhere to be seen anywhere else in the Solar System.
Venus is the second planet of the sun
Venus cools down over time.
"Liquid accumulates in not just one, but countless great lakes."
"Cassini discovered lakes with liquid methane and the earth has a strange cold twin.
"Fascinating and indeed tempting is also that titanium has a complex chemistry and that chemistry is carbon chemistry – the chemistry of life."
Dr. Cox went on to explain how this chemistry might work to make it possible for the moon to grow
He added, "So we found molecules like hydrogen cyanide, the building block of amino acids, and we found molecules called vinyl cyanide, which chemists and biologists speculate could form a kind of cell membrane."
And so all the ingredients for life on Titan are present.
"Now, very few scientists believe that there will be life on Titan today – it's at -180C on the surface, after all."] But because of the presence of all these ingredients, it could be a whole different story if you had Titan
In about 5.5 billion years, the sun will reach the end of its present life cycle, leaving the main sequence and becoming a red giant, engulfin g of mercury, Venus and possibly Earth as well.
It is then expected that it expands and doubles in size and power, which means that sunlight reaches the extreme corners of the solar system.
Dr. Something special for Titan.
He continued, "Given the old expanding sun the vast areas of the solar system receive more solar energy.
"The atmosphere of the Titan will warm.
" Mountains ice will shrink and melt, when the temperatures rise, and the frozen water it contains replaces the liquid methane.
"Mountains become oceans of water, and in a strange turn of fate, at the end of the life of the sun, the last oceanic world of the solar system will awaken to its own biological potential."
