A Difficult Place to Live Life as we know it is unlikely to thrive on Mercury due to solar radiation and severe temperatures. The planet's surface is constantly heated by the Sun to more than 300 degrees Fahrenheit (150 degrees Celsius). All forms of life need a constant temperature range in which to exist. Solar radiation causes great damage to living organisms, causing them to age rapidly. This is particularly true for the skin, which absorbs much of the energy from the Sun's rays. The heat also causes water to evaporate quickly, leaving behind a thin atmosphere composed mostly of carbon dioxide.
It is estimated that only 1% of the planet is not covered by ocean. The remaining 99% is too hot or cold to support life as we know it.
However, some scientists believe that there may be underground reservoirs of water that could provide shelter for some form of life. More research needs to be done in this area before a conclusion can be reached.
A Difficult Place to Live There is no indication of life on Mercury. Temperatures during the day can reach 430 degrees Celsius (800 degrees Fahrenheit) while at night can dip to -180 degrees Celsius (-290 degrees Fahrenheit). Life (as we know it) is unlikely to exist on this planet.
But Scientists Have Discovered Life On Other Stars! Yes, scientists have discovered life on other stars using two different methods. One method involves looking for an Earth-like planet around a star similar to our sun. If such a planet exists, it could have water vapor and clouds like we do. This would be evidence of life because plants need water and oxygen to live. Astronomers use instruments called "telescopes" to look for these planets. The other method involves looking at the color of the star itself. Some stars are orange or red due to the presence of iron. Iron is a common element in the universe and can only be made into objects we call stars when it is in its solid form. As a result, all stars begin their lives as iron cores with thin shells of gas surrounding them. Over time, these gases lose energy and fall toward the center of the galaxy. When they run out of energy, they collapse into objects called neutron stars or black holes. As they collapse, they become more dense and brighten from the energy released as they approach this end point. Eventually, they stop collapsing and remain only as large spheres of incredibly high temperature. These are called white dwarfs.
Mercury is not an easy planet to thrive on, but it is not impossible. It's worth mentioning that without a space suit, you wouldn't last long owing to a lack of atmosphere. Furthermore, Mercury experiences one of the biggest temperature variations in the solar system. From -300 degrees Celsius at night to over 500 degrees during the day. This is why most spacecraft don't live longer than three months.
However, if you were able to survive the first few hours after landing, then you could live out your days among the stars. Think about it: If human beings couldn't breathe air, they would have to rely on liquid oxygen or something similar. The same thing goes for Mercury. Humans need oxygen, so they will have to work with what they are given.
Now, regarding the amount of mercury that would kill an astronaut. The estimated limit for annual exposure is 3.7 milligrams per kilogram of body weight. So for example, if you weighed 70 kilograms (154 pounds), your dose of mercury would be 44 micrograms. This is well below the recommended limit of 300 micrograms. However, since mercury is very toxic, even small amounts of it can be damaging over time.
The only way to avoid being poisoned by mercury is by staying outside of its range. On Earth, this means living more than 100 miles from any source of pollution.
Given that deep craters in Mercury's polar regions might give shielding from the nearby Sun's blistering heat and radiation, a colony on Mercury could be feasible. Any colony would need to be as self-sufficient as feasible in order to be viable. This would include using solar panels to generate electricity for heating and cooling buildings and for powering tools and machinery.
Mercury is so cold that any living thing would have to be well insulated from the temperature changes of night and day. Humans could perhaps build shelters into the ice or rock, but this would not provide much protection from the sun's radiation. It might be possible to grow plants in greenhouses located near where it is warm enough for soil to exist, but these would need to be supplemented with food from elsewhere. It is unlikely that humans would be able to live on Mercury for more than a few months at a time.
It has been suggested that mercury's atmosphere could be used to travel through space safely. However, this would require an enormous amount of energy to escape Earth's gravity. Also, because of mercury's low mass, even a small increase in air pressure would cause it to collapse under its own weight, thus rendering any vehicle made from it impossible to drive away from danger.
Mercury is a very deadly and harsh planet. Extreme temperatures are most likely one of the planet's most harmful characteristics. But don't worry, we have dedicated rooms and transportation with regular and safe temperatures. We are susceptible to meteorites because Mercury has no atmosphere. This makes it easy for objects from space such as asteroids to come in and hit the planet.
Although most asteroids are not dangerous, there are several that can cause mass extinction. If an asteroid were to collide with Earth, it would most likely result in global warming rather than ice ages due to the impact's energy, but either way the outcome would be much the same. The collision would release a large amount of carbon dioxide into the atmosphere, causing global temperatures to rise.
The only protection Earth has is its distance from the Sun. When the Sun is out, Mercury is in darkness. However, when the Sun is out, Earth is also out. So even though Mercury is dark, it isn't completely dark. Light from the Sun reaches it through our atmosphere.
During a full moon, Mercury appears bright because it passes behind the Moon. You won't see Venus or Mars during their evenings because they're always below the horizon.
Astronomers used to think that Mercury was always obscured by Earth's atmosphere, but they now know this isn't true.
