On a Peut-Être Enfin Trouvé la vie sur Mars

Sympa

Pendant des décennies, Mars a semblé être un désert froid et sans vie — jusqu'à maintenant. Le rover Perseverance de la NASA a découvert quelque chose d'incroyable : des formes étranges ressemblant à des graines dans le mystérieux « Canyon de Saphir ». En même temps, les scientifiques ont révélé que Mars possède un noyau interne solide — une caractéristique partagée uniquement par la Terre et la Lune. La conférence de presse soudaine de la NASA amène tout le monde à se poser la même question : avons-nous trouvé la preuve que Mars n'est pas aussi morte que nous le pensions ?

00:00We just have to put out the most remarkable indication that someone has lived on Mars.

00:06Or rather, that an entity has subsisted.

00:09Because, if you imagine the frail being rouge at the eyes grotesque,

00:12remove this idea.

00:14The Martians, envisaged,

00:16resembling rather to the infamous microbes.

00:18I know that it's a bit deceiving,

00:20but a tell discovery could all overcome.

00:23You see this singular motif on the rocks,

00:26semblable to the leopard.

00:28The scientists think it would have been shaped by a ancient form of life.

00:33And no.

00:34It's not a peinture rupestre,

00:36like the ones that have left the first humans in the grottes.

00:39These fine marks are perhaps the vestiges of microbes,

00:42revealing that strange chemical reactions

00:44were happening during their formation.

00:46Rassurez-vous, we will clarify that in a moment.

00:50The NASA had identified this trace

00:53it a more than an an,

00:54and enthusiasm was immédiat,

00:56because they correspond exactly

00:58to the type of rock insolite

00:59that they expected to meet on Mars.

01:01The agency thought that this strange motif

01:03could be a bio-signature,

01:06otherwise,

01:07an indice that a form of life

01:08had existed before.

01:10It could be an element,

01:12a molecule,

01:13a substance,

01:14or, in the case,

01:15a motif

01:17or,

01:18an imprimed leopard.

01:19The scientists

01:20were, however,

01:21prudents.

01:22We can say,

01:23we have found

01:24a life on Mars,

01:25without absolute certainty.

01:26Maybe it was only

01:27a martian rock

01:28to the appearance

01:29singular.

01:30They have therefore

01:31submitted the report

01:32to multiple analysis.

01:33And by

01:34we,

01:35we need to hear

01:36more than a thousand

01:37researchers

01:38from the NASA

01:39across the world.

01:40All recently,

01:41they have published

01:42an article

01:43affirming,

01:44in substance,

01:45we don't see

01:46any other explanation.

01:47And here,

01:48without other explanation

01:49plausible,

01:50we perhaps

01:51have the most convincing

01:52ever obtained

01:53that an entity

01:54ever lived on Mars.

01:56The equipment,

01:57nicknamed

01:58Saphir Canyon,

01:59was captured by

02:00the rover Perseverance

02:01in July 2024.

02:02It comes from

02:03from the fallacy

02:04of the flood

02:05of the flood

02:06of Neretvavalis,

02:07a region

02:08that was formed

02:09by the eaux

02:10that were in the

02:11cratere G0.

02:12And here,

02:13we are talking about

02:14more than 3 billion years.

02:15The scientists

02:16think that at this time,

02:17Neretvavalis

02:18was going through

02:19a rapid river

02:20transport of

02:21sand and gravel

02:22to the lake.

02:23When the eau

02:24finally removed,

02:25it was finally

02:26removed

02:27where the Saphir Canyon

02:28was discovered.

02:29After

02:30recovered

02:31the rover Perseverance

02:32has followed

02:33its exploration

02:34of the valley

02:35of the flood

02:36to better

02:37the place

02:38where the roaches

02:39were formed,

02:40and to understand

02:41how the taches

02:42of a pelage

02:43of léopard

02:44could appear.

02:45This step is

02:46determined

02:47to identify

02:48precisely their origin,

02:49to evaluate

02:50whether the roaches

02:51truly have a trace

02:52of an activity

02:53biologist.

02:54In other words,

02:55these types

02:56come from

02:57any ordinary

02:58or have been

02:59made by microbes?

03:00The instruments

03:01of the rover

03:02have revealed

03:03that the roaches

03:04of this region

03:05are composed of

03:06argile and

03:07limons,

03:08used to preserve

03:09the signs of

03:10microbe

03:11anciens.

03:12They also contain

03:13carbon

03:14organic,

03:15sulfur,

03:16fer oxy

03:17and phosphorus.

03:18And you know

03:19who takes part of

03:20such elements?

03:21The microbes.

03:22Using these

03:23ingredients

03:24as source

03:25energy

03:26and,

03:27using them,

03:28the taches

03:29of léopard

03:30that we distinguish

03:31today

03:32from the images

03:33in high resolution.

03:34Remember

03:35when I mentioned

03:36the idea

03:37that these products

03:38could be

03:39exactly

03:40that.

03:41Imagine that you

03:42taste a hamburger

03:43called the galaxy burger,

03:44accompanied

03:45of a singular sauce.

04:16Even if

04:17you observe

04:18the researchers

04:19can already

04:20take some indication.

04:22For example,

04:23the motif

04:24shows the presence

04:25of two minerals

04:26rich in fer,

04:27the vivianite

04:28and the grigite.

04:30Sur Terre,

04:31the vivianite

04:32appears often

04:33in the sediment

04:34close to the organic matter

04:35in décomposition

04:36or in the humid areas

04:37or in the humid areas.

04:38In comparison,

04:39the microbes

04:40can also generate

04:41the grigite.

04:42When we find the two

04:43together,

04:44we suggest

04:45that they are formed

04:46at the rate of

04:47the transfer of electrons

04:48between the sediment

04:49and the organic matter

04:50could be a real signature

04:53of the microbial

04:54because the microbes

04:55exploit these reactions

04:56to obtain

04:57energy and grow.

04:58Ainsi,

04:59for reprendre

05:00the analogy

05:01of the hamburger,

05:02these taches

05:03would be comparable

05:04to the gouttes

05:05of sauce,

05:06the residue

05:07given by the

05:08acquisition of energy.

05:09However,

05:10this is not the only

05:11hypothesis

05:12envisaged.

05:13The team has also

05:14revealed the possible

05:15presence

05:16of the hematite

05:17in the Roche.

05:18And if Mars

05:19merits the name

05:20of the rouge,

05:21it is largely

05:22because of

05:23this mineral dense

05:24capable

05:25of adopting

05:26then

05:27of the millenaires

05:28as pigments

05:29for the peinture.

05:30The researchers

05:31think that these

05:32léopardy

05:33could be appeared

05:34when the chemical reactions

05:35have transformed

05:37some parts of the

05:38Roche

05:39of the red

05:40into the red

05:41This process

05:42can liberate

05:43and phosphate

05:44and maybe

05:45produce

05:46these

05:47and here

05:48this

05:49is the

05:50decisive

05:51of

05:52energy

05:53exploitable

05:54by the microbes.

05:55For the

05:56time,

05:57it is

05:58that

05:59we can affirm

06:00that these

06:01chemicals

06:02are well

06:03and well

06:04present in the

06:05Roche.

06:06But

06:07like in an investigation,

06:08discover a

06:09sauce

06:10doesn't prove

06:11nothing to you.

06:12So,

06:13even if these

06:14minerals

06:15are ideal

06:16for the

06:17micro-signature

06:18they would have

06:19all as well

06:20could be formed

06:21in a biotic way

06:22otherwise,

06:23without any intervention

06:24in the life.

06:25Yes,

06:26this could be

06:27happening.

06:28But for that

06:29naturally,

06:30without an intervention

06:31microbial,

06:32two conditions

06:33would be required,

06:34high temperatures

06:35and a

06:36acid.

06:37It is the only

06:38that allows

06:39to these

06:40chemical processes

06:41to act

06:42and leave

06:43the most intriguing

06:44the researchers

06:45found no evidence

06:46that these

06:47have been exposed

06:48to a strong heat

06:49or an acid environment

06:50which is their

06:51perplexity.

06:52They do not

06:53just simply

06:54propose other

06:55explanations.

06:56So,

06:57it should be

06:58a bio-signature

06:59right?

07:00Well,

07:01perhaps not.

07:02There is indeed

07:03a possibility.

07:04There is indeed

07:05a possibility.

07:06Some organic

07:07could react

07:08even

07:09at low temperature.

07:10And perhaps,

07:11yes,

07:12perhaps,

07:13that we observe

07:14this phenomenon

07:15for the first time.

07:16It is precisely

07:17what makes

07:18so difficult

07:19a confirmation

07:20absolute,

07:21determining

07:22if we see

07:23the work of

07:24ancient microbes

07:25or a simple

07:26processus

07:27natural.

07:28Thus,

07:29we have

07:30more questions

07:31than questions

07:32that answers.

07:33For the time,

07:34we can expect

07:35that one day

07:36it will be

07:37to study

07:38on a laboratory

07:40study

07:41and

07:42that we

07:43could not

07:44affirm

07:45that it is

07:46a bio-signature.

07:47One thing is certain,

07:48this

07:49discovery

07:50is

07:51the most

07:52approach

07:53that we have ever

07:54reached

07:55to the identification

07:56of a martian life.

07:57In fact,

07:58to distinguish

07:59a bio-signature

08:00potential

08:01on the red

08:02is

08:03revolutionary.

08:04This

08:05discovery

08:06is also

08:07important

08:08because of

08:09the age

08:10of the

08:11rock.

08:12This

08:13is

08:14the most young

08:15ever studied.

08:16Here,

08:17scientists thought

08:18that

08:19there were

08:20different signs

08:21of life

08:22that

08:23there were

08:24much more

08:25older.

08:26Or,

08:27nothing was detected

08:28in these

08:29ancient rocks.

08:30Finding a

08:31bio-signature

08:32potential

08:33in a young rock

08:34suggests

08:35two pistes.

08:36First,

08:37that Mars

08:38could have been

08:39habitable

08:40longer

08:41or

08:42that we

08:43could have

08:44seen

08:45more

08:47difficult

08:48to discern.

08:49One day,

08:50our technology

08:51will be able to

08:52reveal it.

08:53This

08:54also leads

08:55to one of the

08:56most fundamental questions.

08:57Are we really

08:59seuls

09:00in the universe?

09:01Have we finally found

09:02the answer?

09:03Not exactly.

09:04But it's

09:05the progress

09:06of humanity

09:07to answer

09:08this question.
