We're Going On A Little Journey Through The Solar System #1
Mankind did not begin to be interested in the sky in the last century. Perhaps, even in the most ancient times of human history, the sky has always been the focus. Curious people of the distant past, which we can call the scientists of that period, thought that they could solve the mysteries of the existence of planets and stars by looking at the sky. Our curious ancestors, who achieved successful results by periodically observing the sky, pioneered our space travel.
These people managed to create a certain system by taking note of their investigations and shed light on the progress of today's scientists. There are many scientists who have worked in this field and achieved very successful results in both western and eastern societies.
In this article, I would like to give you information about the atmospheres of both the Sun and some planets in our system. So let's start…
Our planet has an atmosphere made up of gas molecules that it can hold around by gravity. This gas mass protects life on Earth by absorbing high-energy solar radiation and balancing the temperature difference between day and night. Of course, all celestial bodies with sufficient gravity can have an atmosphere, even if they contain different components.
Now, let's take a journey through our solar system and get to know the atmospheres of celestial bodies.
Let's begin our journey with the star that gives our system its name, namely the Sun. At the top of the Sun's bright surface is an atmospheric layer called the chromosphere. The thin red stripe visible as the Moon obscures this bright surface during a solar eclipse is the chromosphere layer. Above the chromosphere extends the corona layer, which is likened to a crown due to its shape. While the surface temperature of the Sun reaches about 5800 degrees Celsius, the temperature in the corona layer can reach 2 million degrees Celsius.
The increase in temperature with distance from the surface continues to occupy the minds of scientists as a mystery that has been waiting to be solved for years.
Now let's move away from the Sun and stop by the smallest planet in our system, the closest to the Sun. Due to its small mass and exposure to strong solar winds, Mercury's atmosphere is very thin. When we look at the changing air temperatures throughout the day on Mercury, we can better understand the importance of our planet's atmosphere. On Mercury, the daytime temperature exceeds 430 degrees Celsius, while at night it approaches -180 degrees Celsius.
Let's reach Venus, the planet that moves away from Mercury and surprises with its warmth. Venus is the planet with the highest surface temperature in our system. The atmosphere of Venus, which offers a yellow sky view, traps heat so much that its surface temperature can rise above 480 degrees Celsius. The planet's atmosphere is mostly carbon dioxide, and its clouds are sulfuric acid. The atmosphere of Venus is a very good example to see how carbon dioxide, which triggers global warming on our planet, increases the surface temperature of a planet.
Of course, it is inevitable that the atmospheric pressure of Venus, which has such a thick atmosphere, is also quite high. Being under the atmosphere of Venus is equivalent to being at an ocean depth of almost one kilometer in terms of pressure.
When you ascend to the upper layers of Venus' atmosphere, pressure and temperature become more manageable. Scientists looking for life in space think that an environment suitable for life can be found in suitable conditions in the upper parts of Venus' atmosphere. In fact, last year, a group of researchers announced that they had found a living molecule in one of these sections.
That's it for today. I'm thinking of writing a sequel.
