The solar system presents various beautiful objects that can be enjoyed from the surface of the Earth. One of which is Venusthe brightest and most beautiful object in the night sky that humans can witness.
Even though it has enormous beauty, it turns out that Venus is an inhospitable planet for life and is often referred to as the planet of hell.
The planet Venus is known as a planet that is poisonous and hot so that humans can never step on it.
Nevertheless, the scary Venus once had a state where this planet was suitable for human life, you know.
Besides that, it turns out that on this planet there have been oceans. Come on, look at the information quoted from Science Alert.
Comparison of the Conditions of Venus and Earth
Even though Venus is currently an uninhabitable planet, it shares some similarities with Earth. The two planets are very similar in size, mass, density to composition.
The similarities between Venus and Earth then raise questions regarding the habitability of this planet. The answer to this question is revealed through a study that Venus once had habitable conditions.
Long ago, Venus was predicted to be a planet we could live on and have water on its surface. However, currently the planet Venus has turned into a dry and arid planet.
It is estimated that the water that Venus has existed more than 3 billion years ago, which was revealed by planetary scientists Alexandra Warren and Edwin Kite of the University of Chicago. But the results of this study are doubted by several other scientists.
Currently Venus is very dry and has low oxygen levels. Venus’s atmosphere consists of 96% carbon dioxide, 3% nitrogen and small amounts of other gases such as sulfur dioxide.
It is known that Venus’ atmosphere is very thick with more than 90 times that of Earth’s atmosphere and is battered by strong winds and rain of sulfuric acid. The impact of the thick atmosphere of Venus is that the heat inside Venus cannot escape.
Venus has the hottest surface temperature when compared to all the planets in the solar system. The average surface heat of the Planet Venus can reach around 464 degrees Celsius. This means that Venus is very hot and uninhabitable.
Venus’ current state raises questions for planetary scientists because Venus is so Earth-like. In addition, through several climate models it is also known that Venus may have had water less than a billion years ago.
Venus Livable Modeling
If Venus ever had oceans then the lack of oxygen in the Venusian atmosphere is confusing.
Venus should have oxygen which is produced from the photodissociation process of evaporating water into the atmosphere.
Warren and Kite then built a model based on habitable Venus to find out where the oxygen was going.
They placed an ocean of water on the surface of Venus and added a mechanism that is thought to cause Venus to lose oxygen.
They ran the model 94,080 times and deemed it successful when the levels of dioxygen, water and carbon monoxide were at the same level as those gases’ limits in Venus’ current atmosphere.
Unfortunately, the success of such modeling has a very small percentage. It’s likely that Venus is deprived of oxygen by either leaking into space or being sequestered in oxidized magma such as basalt on the planet’s surface.
In addition, the oceans are thought to have dried up about 3 billion years ago.
Then to estimate the amount of water that is owned by Venus, the researchers carried out calculations by determining how active Venus’s volcanism was in the past.
However, the magnitude of Venus’ volcanic activity is limited by the amount of radioactive argon present on the planet.
It was found that the depth of the Venusian ocean is no more than 300 meters. The figure shows that the depth of the sea Venus less than 10 percent of the average ocean depth on Earth, which is 3,688 meters.
