Study: Venus’ extreme atmosphere may have been related to Jupiter’s collision in ancient times.

According tomedia reports, Venus’ extreme atmosphere may be related to the gas giant jupiter in ancient times collision, the collision may fundamentally change The orbit of Venus and lead to the loss of a large amount of water reserves. A new research paper describes how Jupiter’s gravitational influence as it moves far beyond the solar system has set it on the path to becoming an uninhabitable planet as we see it today.

Study: Venus' extreme atmosphere may have been related to Jupiter's collision in ancient times.

To do this, the researchers built a computer model of the solar system to simulate the position of planets, their different gravitational effects, and their effects on each other’s orbits.

Stephen Kane, an astrobiologist at the University of California, Riverside, who led the study, said: “What’s interesting about Venus today is that its orbit is almost perfectly circular. Through this project, I want to explore whether the orbit has always been circular, and if not, what does it mean? “

The eccentricity or roundness of the orbit is measured on a scale of 0 to 1. Orbital eccentricity of 0 means that the planet’s orbit is completely round. Conversely, if a world’s orbital eccentricity is 1, it simply catapults itself into space. Venus is known to have an eccentricity of 0.0006, the roundest in the solar system, while Earth has an eccentricity of 0.0167.

Models show that Jupiter’s orbit was closer to the sun about a billion years ago, when Venus had an eccentric orbit of 0.3, which, according to the researchers, would have made it a more habitable planet.

However, as the gas giant moves outwards, its powerful gravity interferes with Venus forcing it into a more rounded orbit. During this orbital forced collision, tidal heating and other processes can cause periodic heating and cooling of the planets.

The team believes that changes in eccentricity may have accelerated Venus’ atmospheric evolution and caused it to lose a lot of moisture. This, in turn, could lead to an out-of-control greenhouse effect that would make the planet’s surface uninhabitable.

Although Venus is very different from Earth’s evolutionary history, it can still be the host of life.

Scientists recently discovered a gas called hydrogen phosphate in Venus’ atmosphere. On Earth, hydrogen phosphate is produced by bacteria and microorganisms, so the discovery is considered potential evidence of organic life in the extraterrestary atmosphere.

Kane believes the life form may be the last surviving species on a planet that has undergone environmental uphea changes.

The study was published in the Journal of Planetary Science.
