Why are signs of life on Mars so mysterious?

Did you know that NASA recently announced that it had found signs of life on Mars? Let me explain!

You may not have heard, but NASA made a very recent announcement – at the beginning of January, to be more precise.

NASA, the American Space Agency, which is responsible for research and development of space exploration technologies and programs, reported that one of its probes had made a discovery during its expedition to Mars.

The probe found some signs that, at first, could prove the existence of extraterrestrial life. 

Are you curious? If you are interested in this topic and want to stay up to date with this new development, this material was made especially for you.

Throughout the content, we will talk a little more about these signs of life on Mars.

What do they mean, why are they – so far – considered mysterious and what are the next steps to solve this mystery. Enjoy reading!

What are these signs of life on Mars?

At this very moment, many of you who are reading must automatically be imagining those small green creatures that live hidden when we talk about the discovery of life on Mars, right?

But in reality it is not quite like that.

Leaving aside all this imagination linked to science fiction films that exist out there, the potential signs of life on Mars are much more subtle than one might imagine.

These possible signs of life on Mars are nothing more than traces of carbon. This type of evidence could indeed indicate the existence of life on Mars, but on a more primary level. We are talking about something like microbial life.

As soon as the discovery was announced, the scientists responsible reported that, among the content collected during the expedition, several samples contain a very specific type of carbon.

One of the factors that excited the scientists and researchers involved in the discovery was that these carbon traces are directly linked to biological processes that occur here on Earth.

Here on our planet, the carbon that has been found in residual traces on the red planet is responsible for some of the actions that involve our nature.

Among the most common are the processes of food metabolization and even photosynthesis that occurs here on Earth.

This is, to say the least, quite curious, right? 

Why are signs of life on Mars mysterious?

Even though the signs may seem simple, such a discovery brings with it a great deal of mystery.

To begin with, we can start with the most skeptical aspect of the story.

With this discovery alone, it is impossible to define with certainty the origin of this carbon and whether it is really the result of a possible presence of extraterrestrial life on Mars.

From what is known so far, these carbon residues may be the result of other factors.

Among them, there could be some kind of geological, physical or even chemical activity that occurs on the red planet and we don't even know about it. 

Even though humans have already carried out several expeditions to explore Mars, much information regarding the planet still remains to be discovered.

Now, thinking about the possibility that this carbon footprint is actually a sign of the existence of extraterrestrial life. 

This discovery still does not provide enough data for us to know whether the eventual presence of life exists to this day.

There is also the possibility that carbon represents a species of life that once existed at some point in the planet's history, but has now become extinct.

What is the future of research after the discovery of these signs of life on Mars?

The fact that this discovery has a rather mysterious origin only served to excite researchers, scientists and astronomers. It is very likely that research will continue, both in the area where the carbon was discovered and in other areas of the red planet.

The Curiosity rover – the probe responsible for the discovery in question – has already confirmed its presence in this next stage of the research. As the probe was the main responsible for this revealing discovery, those responsible for the vehicle are quite optimistic about this new venture by Curiosity.

It is estimated that he must return to the place where the samples in question were found to try to collect new materials that could help complete this puzzle.

Or, in the most pessimistic of theories, so that it can at least secure new samples similar to what was collected during its previous exploration.

In addition to new expeditions in search of materials, the next step in relation to this research is to bring the collected fragments to be analyzed in laboratories here on Earth.

With more advanced equipment and more efficient research resources, it will be much easier to trace a timeline for this carbon sample, starting with its origin until the moment it was found by Curiosity.

But until those samples get here and all the research needed to discover the origin of the carbon is done, we have to wait and watch.

So, we will see what the next steps will be and whether such a discovery really means the first proven evidence of the existence of extraterrestrial life. 

Conclusion

So, what do you think?

When it comes to this discovery of potential signs that there is life on Mars, which side do you take?

Is there a side that believes that this type of discovery has a completely logical explanation and that it has nothing to do with the presence of life?

Or do you think that, even if it is a relatively simple signal, this is the first step towards discovering the first sign of life outside our planet?

Let's wait for the next discoveries – and the most advanced research on the material found – and what the result of the studies carried out by the experts will be. 

Only then will it be possible to say with greater certainty whether the residual carbon footprint is part of some type of life on Mars.

Or if the sample is just a natural event that happens on the planet, but that we are not yet aware of.
