Scientists say they've been looking for aliens in the wrong place

Missions to potential extraterrestrial planets worth billions may have been in vain if a new study is believed.

Scientists claim that our research of ET is too focused on worlds showing signs of water. Instead, missions to the extraterrestrial worlds should instead look for "basic ingredients" for life on Earth, including nutrients like phosphorus, computer models show.

Scientists have said that alien hunting probes en route to distant worlds will struggle to find life because these "bioessential" elements probably only exist in hard-to-reach oceans -marins. Scroll down to the video

  Alien hunters searching for inhabited planets outside our solar system should look for more than just water, scientists say. On the photo is the impression of a water-rich exoplanet orbiting a red dwarf star

Alien hunters searching for inhabited planets outside of our solar system should look for more than just water, say the scientists. In a previous research, questions about the habitability of moons and planets usually focus on the presence of water, mainly because there is life almost everywhere on Earth where the water is found. water is present.

Regarding exoplanets, astronomers look at whether they are in orbit in the "habitable zone" of their star – the region where the temperature is just right so that the water exists at the surface from a planet. "There are of course other ingredients necessary for life as we know it," says Harvard University astronomer Professor Avi Loeb at Live Science

On Earth, elements " bioessentials "like phosphorus and nitrogen in DNA, the essential model for all life on our planet.

To analyze the importance of these ingredients on other worlds, researchers examined their prevalence in liquid oceans below the surface. ns.

Frozen worlds such as Jupiter's Europa Moon and Saturn's Moon Enceladus are among the first targets of future NASA and Esa hunting missions because of their underground oceans which, according to scientists , could harbor microbial life. The search for extraterrestrial worlds should look for some of the "basic ingredients" for life on Earth, including phosphorus.

Using ocean-based models, researchers have discovered that the underwater oceans like Encelaus and Europa we know that he is weak.

They discovered that resources like phosphorus, nitrogen, and sulfur – as well as trace metals like iron and molybdenum – were depleting rapidly in these environments.

Underground oceans that are alkaline or neutral and have hydrothermal vents – which are a large number of potentially available radars on NASA's radar – would soon run out of phosphorus – which the team has qualified essential ingredient for life. Not long after their formation

How important is phosphorus for life on Earth and how did it happen?

Although it is nowhere as abundant on Earth as carbon, hydrogen or oxygen

It helps to form the backbone of long chains of nucleotides which constitute DNA – the constituent elements of biological life as we know it.

Phosphorus is also vital for cell membranes and the carrier molecule of cellular energy. ATP

Meteorites probably arrived on Earth aboard meteorites billions of years ago.

Meteorites are believed to contain a phosphorous mineral called schreibersite.

Scientists have recently developed a synthetic version of schreibersite that reacts chemically with organic molecules, showing its potential as a nutrient for life

because the sources that add these ingredients to the ocean do not do not outweigh the wells.

Lead author of the study, Dr. Manasavi Lingam, told Universe Today: "If the wells are much more dominant than the sources, it could indicate that the elements would be depleted relatively quickly.

we drew on our knowledge of the Earth and coupled it to other fundamental parameters of these oceanic worlds such as the pH of the ocean, the size of the world, etc., known by theoretical observations / models.

"Phosphorus can be completely eliminated from the oceanic world below the surface in a very short time compared to the age of the solar system – millions of years," they told Live Science. on the Earth's oceans, researchers have discovered that underwater opportunities like those of Encelaus (the artist's print) and Europe shelter the key ingredients of life as we know them ” class=”blkBorder img-share” />

using Oceans-based models, researchers have discovered that the oceans are underwater. and Europe are hosting the key ingredients of life as we know it

NASA will use "ROBUST SCIENCE" TO SEE FOREIGNERS

NASA has revealed a series of new projects that could finally prove Existence of extraterrestrial life.

Bringing together a group of leading researchers in astronomy, biology and geology as part of the new project to "take stock of our knowledge in the quest for life on a distant plane" called the Nexus for System Science from the exoplanets, or NExSS, he hopes to answer the questions of which planets could accommodate life – and what could this life look like.

] 19659002] "We move from life theory elsewhere in our galaxy to a robust science that will ultimately give us the answer we seek to this profound question: Are we alone? says Martin Still, NASA exoplanet scientist at headquarters, Washington

In a set of five papers published last week in the scientific journal Astrobiology, NExSS scientists revealed the first project, inventing the signs the most promising of life.

They looked at how to interpret the presence of biosignatures, should we detect them on distant worlds.

A major concern is to ensure that science is strong enough to distinguish a living world from a barren planet disguised as one. 19659002] Through their work with NExSS, scientists attempt to identify the instruments needed to detect the potential life of NASA's future flagship missions

The detection of atmospheric signatures of some potentially habitable planets may be earlier than 2030 although planets really livable or have life will require further study.

Researchers have said that elements like phosphorus will only exist at low concentrations This could create problems for alien hunting missions sent to distant worlds by NASA, such as NASA mission Europa Clipper – whose launch is planned at the moment. The scientists said their findings show that the chances of these missions finding their lives in the underground oceans is slim.

They added that this does not mean that these missions are a waste of time and resources, as they help us better understand the underground oceanic worlds.

"Although our model predicts that future space missions to these worlds may have low chances of success in detecting extraterrestrial life, we believe that such missions still deserve to be pursued", said Dr. Lingam. because they will provide an excellent opportunity to: (i) test and / or falsify key predictions of our model, and (ii) collect more data and improve our understanding of oceanic worlds and their biogeochemical cycles.

the researchers said that their study looked only at the ingredients for life as we know it.

Microbes on other worlds can rely on other building blocks that scientists on Earth have never considered, they said.

WHAT ARE THE MAIN DISCOVERIES OF HUMANITY IN ITS SEARCH FOR FOREIGN LIFE?

Discovery of Pulsars

The British astronomer Lady Jocelyn Bell Burnell was the first to discover a pulsar. in 1967, when she spotted a radio pulsar

Since then, other types of pulsars emitting X-rays and gamma rays have also been spotted.

Pulsars are essentially rotating, highly magnatised. Neutron stars, but when they were discovered, it was believed that they could come from extraterrestrials.

& # 39; Wow! & # 39; radio signal

In 1977, an astronomer looking for an extraterrestrial life in the skies over Ohio detected a powerful radio signal so powerful that it was impossible. he wrote enthusiastically "Wow!

  In 1977, an astronomer looking for extraterrestrial life in the skies above Ohio spotted a powerful radio signal so loud that he wrote enthusiastically "Wow! next to his data

In 1977, an astronomer seeking an extraterrestrial life in the skies above Ohio spotted a powerful radio signal so loudly that he wrote enthusiastically "Wow! next to his data

The 72-second explosion, spotted by Dr. Jerry Ehman with the aid of a radio telescope, came from Sagittarius but did not correspond to any known celestial object.

Conspiracy theorists have stated that the & # 39; Wow! Signal, which was 30 times stronger than the background radiation, was a message of intelligent aliens.

Fossilized Martian Microbes

In 1996 NASA and the White House made the explosive announcement that the rock contained traces The meteorite, cataloged Allen Hills (ALH) 84001, s & # 39 is crushed on frozen waste from Antarctica 13,000 years ago and was recovered in 1984.

Photographs were published showing elongated segmented objects that seemed incredibly realistic.

However, the excitation did not last long.Other scientists wondered if the meteorite samples were contaminated.

They also argued that heat produced when the rock has been dynamited into space may have created mineral structures that could be confused with microfossils.

Behavior of the Tabby Star in 2005

L & rsquo; Star, known as KIC 8462852, is located 1,400 light-years away and has amazed the astonomers since its discovery in 2015.

a much faster rate than other stars, that some experts have suggested is a sign of extraterrestrials exploiting the energy of a star.

The star, also known as KIC 8462852 AT 1,400 light-years, astonomers have been baffled since their discovery in 2015 (artist's impression)

Recent studies have "eliminated the possibility of a foreign megastructure", and suggest rather that it is not the same. a ring of dust could be at the origin

Exoplanets at the Goldilocks in 2015

This year in February, astronomers announced that they had spotted a star system of which satellites could support life only 39 light-years away.

Earth-like planets have been discovered in orbit around the neighboring dwarf 'Trappist-1', and all could have water on their surface, l & # 39; 39, one of the key components of life.

Three of the planets have such good conditions, life may have already evolved on them.

Researchers say that they will know if there is life on one or the other planet over a decade, and they said "this is only the beginning ".
