Life on Other Planets

By: Amanda D.

InformationFor many years humans believed that we were the only people in this universe.

Theories and thoughts have began to change and new ideas have formed.

A planet that is being highly research to try and find a form of life is Mars.

Here on Earth Hydrogen, Carbon, and Oxygen are the top three ingredients in life on Earth, and those three things is what the universe is mostly comprised of, other than Helium, with that piece of knowledge maybe another planet in our universe can sustain life

EvidenceIn 1984 a meteorite was found in Antarctica, this meteorite had come from Mars thousands of years ago.

NASA Scientists researched the meteorite and found four concepts that they believe could help to prove to people that a form of life does exist on Mars

Four ConceptsCarbonate Globules- The carbonate patterns form a unique signature of life, and these patterns are consistent with how terrestrial bacteria operate.

Polycyclic Aromatic Hydrocarbons (PAHs)-Organic compounds usually created by bacteria were present in the meteorite. There has been much controversy about whether or not the PAHs are contaminants from the Antarctic environment, or are present from Mars.

Magnetite Globules-These globules are created by bacteria on Earth as well as some chemical processes. The tear-shape in the evidence that was found can only be created by bacteria, which is a form of life

Microscopic Fossil-like StructuresThe most dramatic evidence of all, were of pictures shown at the press conference of worm-like structures present in the meteorite.

Conclusion of Mars

With that sort of almost concrete evidence, it is hard to dispute, but scientist are in a mass debate of whether there really is life

Hopefully in the future our technology will be better, so that we can get more in depth research, and try to piece together the puzzle of Mars

The life on Mars that we are looking for is not a complex structure like us, but a simple form of life such as bacteria

FartherWhile Mars is near us, and could have the potential to have a form of life. The question that most scientist turn to, would be, is their a form of complex structure of life like us out in the universe somewhere?

GalaxyOur galaxy is one of many billions. There are trillions and trillions, and trillions of stars in our universe.

In reality we are just a miniscule mark in the universe.

With being such a small impact in a massive universe, it is very hard to say that we are the only living things out there. Milky Way

Galaxy

QuestionQuestions that are commonly asked are, “Why have we not communicated with other living things if they are out their?

The answer to that is quite simple. Radio waves are an effective way to send a message through space. The message will eventually arrive, but the amount of time it takes is unbelievable. To communicate with the nearest galaxy to us is the Andromeda Spiral Galaxy. In order for them to get one message it would take over 2,000,000 years for it to reach them.

Continued…Another problem with communication is the fact that maybe other planets have tried to contact us, but we didn’t have the technology to receive radio waves, and now they just figure that there is nothing on our planet, just like we feel here on Earth, that we are alone.

In comparison trying to communicate with other planets is like shooting at a target with a blindfold on and the lights off, there is a large room for error.

ConclusionDue to the fact that it is nearly impossible to try and communicate with distant galaxies, many people have dropped the thought that other life forms exist. However, I do not give up the hope that there are other life forms in this universe. It seems very egotistic for us to think that other life forms do not exist. Since we do not really have much concrete evidence on this theory their really isn’t to much evidence to back up my thoughts. What is important though is your opinion, and I personally do believe that somewhere in our galaxy there are other living beings.
