Life in space is very likely but millions of light years outside our solar system. On Mars, it may have existed once when there was water on Mars. However, currently, according to current data, life on Mars does not occur. Perhaps life exists in the oceans under the ice on one of the moons of Jupiter, i.e. called Europe (Jupiter II). Jupiter's natural satellite - Europe is the fourth largest moon of Jupiter in the Galilean moons group and the sixth largest satellite in the Solar System. The moon Europa has not yet been thoroughly researched in this matter, so science fiction movies have already appeared, suggesting that there are mysterious forms of life in the oceans of Europe.
Do you agree with me on the above matter?
In the context of the above issues, I am asking you the following question:
Can there be life somewhere in the Solar System outside Earth?
Please reply
I invite you to the discussion
Thank you very much
Best wishes
> Can there be life somewhere in the Solar System outside Earth?
Asking whether life can exist is very different from asking whether life does exist.
We have barely begun to explore possible biomes in the solar system - the subsurface arctic cryosphere of Mars has not been explored by anything other than radio waves.
Can life exist there? Maybe. Psychrophiles exist on Earth that tolerate similar conditions.
Can life have started there? We do not know.
We've explored Europa from flybys - no landers are foreseen for the near future, let alone probes able to explore its oceans. Similarly, the subsurface seas of Enceladus are at present utterly unknown to us - we simply know that they exist.
Can life exist there? Maybe. Ocean-going lifeforms are ubiquitous on Earth.
Can life have started there? We do not know.
Not all questions in science have answers: I certainly do not think that we can answer 'can life thrive under Europa's crust' in any simple fashion: we're still very much in the dark about the origin of life on Earth, let alone its development and progression in other biomes.
Note: We do not have evidence for life on Mars (although Dr Levin and many others might disagree). We cannot say that ' life on Mars does not occur' as it is quite impossible to demonstrate that that is so.
It is rather "academic question" what all our Mother Nature needs to create the life. If only a plentitude of chemical compounds + liquid water + some energy (heat, light, electric discharge, ionization radiation) + lot of time, ..... then some kind of life should exist e.g. on Jupiter's moon Europa. All is available there: chemicals from ocean rocky bed, liquid water under icy cover, lot of heat from Jupiter's tidal force and billions years of time... But it is really enough ?
Yes. Whether there is, is another matter. But all you need is some kind of liquid that allows movement of molecules from one place to another and some kind of energy source. The basic 'organic' molecules that are required for life are present even in inorganic sources, such as meteorites, and are almost certainly present in many places in the Solar System. So there certainly could be life elsewhere in our neighborhood.
Since the Earth is the only planet whose surface is not exposed to either the vacuum of space or high-intensity cosmic and solar radiation, the most likely places are somewhere inside one of the moons of Jupiter or Saturn, some of which appear to have oceans beneath their icy crusts, and also appear to have some kind of internal heat source (probably as a result of tidal stresses caused by their planets). So, for example, Europa and Enceladus are thought to be good places to look, though looking at the bottom of an ocean covered by miles of ice is not going to be easy. I more or less reject Titan, because although it has a thick atmosphere and a surface made of solids and liquids, the temperature is almost certainly far too low to allow for the development of any kind of life. And although some of the other large moons might harbor life, when and if we are capable of looking for it, it is probably just as likely as not that we will not find any evidence of it.
Various objects on different hierarchy levels of organisation had been suggested earlier. (Let us mention only Bertalan Nagy, and Claus Klein?) However, structures on more than one hierarchy level had been found in the Martian meteorite ALH-84001 by David McKay et al (1996). More and more strict requirements are fulfilled, if those are considered, which ahd been found by the groups of Gyollai et al (2019), and Polgári et al (2019) as shown in their papers in Open Astronomy. Earlier conference papers concluded the possibility of existence of life in the form of Fe-oxidizing microbes in EANA, (Aarhus,) Chondrite (London) and other events. The last papers had shown the possibility of existence 3 or 4 hierarchy levels coherently. So my answer is: yes.
The direct answer to the question "Can there be life..." is that there is potentially a non-zero possibility. Testing the null hypothesis, that there "cannot be life" is quite difficult. Evidence for and against both positions exists. However strong the arguments for life, space provides many harsh environments, yet we know deep in our oceans at hydro-thermal vents or in volcanic geysers there is life. Seeing volcanism on other worlds at least provides a necessary energy source. But the null hypothesis has a fatal flaw. We know of one location where there is life, and we discover over and over again that its conditions are not very special in the Universe. The famous Drake equation goes much further, to single out intelligent life that still exists today and wishes to communicate. But in very sad news for the null hypothesis, even it is non-zero.
Most scientists are sure that life outside of earth can exist and emerge. Microbial life that is. Even now on Mars life may be present. And possibly on Europe...

NASA Rover on Mars Detects Puff of Gas
That Hints at Possibility of Life
The Curiosity mission’s scientists picked up the signal this week, and are seeking additional readings from the red planet.
By Kenneth Chang
- June 22, 2019
Mars, it appears, is belching a large amount of a gas that could be a sign of microbes living on the planet today.
In a measurement taken on Wednesday, NASA’s Curiosity rover discovered startlingly high amounts of methane in the Martian air, a gas that on Earth is usually produced by living things. The data arrived back on Earth on Thursday, and by Friday, scientists working on the mission were excitedly discussing the news, which has not yet been announced by NASA.
“Given this surprising result, we’ve reorganized the weekend to run a follow-up experiment,” Ashwin R. Vasavada, the project scientist for the mission, wrote to the science team in an email that was obtained by The Times.
The mission’s controllers on Earth sent new instructions to the rover on Friday to follow up on the readings, bumping previously planned science work. The results of these observations are expected back on the ground on Monday.

Investigation going to say some livings posibility but
No proxies
I think that life is omnipresent, anywhere in space, once we think of Consciousness as the life-generator par excellence while not being bound to a definite enclosure (ex. body)!
Understanding that Consciousness performs non-locally plus enclosure-independently, life is necessarily omnipresent, so virtually everywhere, even when deprived of the known enclosure forms!
Based on the above interesting discussion, I formulated the following key questions: - When will man check if life has existed on Mars before?
- When will a man-sent probe-lander reach Jupiter's moon Europe, which will examine whether there are any forms of life under this ice cover in the ocean on this moon of Jupiter?
- Is there any other planet or moon in the solar system where you can search for any life forms?
What do you think about this topic?
What is your opinion on this topic?
Please reply
Earth is the only place that we know for certain supports life. In the meantime, NASA is working hard now to discover whether there is life on Mars. The United States and other countries have been sending spacecraft to orbit or land there since the 1960s, and each mission teaches us more about this fascinating planet. We have learned that even though Mars is more similar to Earth than anywhere else in the solar system, and therefore is a good place to look for life, it is still different from Earth in many ways.
A compass points to the north pole on Earth because our whole planet acts like a giant magnet, but Mars does not act this way. Besides turning a compass needle, Earth's magnetic field turns away dangerous particles of space radiation. Without a magnetic field on Mars and with much, much less air than on Earth, more harmful space radiation reaches its surface. Although some measurements tell us there probably is water on Mars, there is far less than on Earth. And it is so cold there that most of the water is probably not liquid but rather is ice. Overall, Mars would be a pretty uncomfortable place to try to live!
Nature can not sustain singularity. It must have life some where in the universe may be outside this solar system. Now the question is when we are going to get exact and clear information about this. Only time can tell. Hope for the best at earliest.
Forget all other planets of the Solar System for life like ours. Maybe some of the moons can support small forms of life like microscopic plants or animals.
Need to look elsewhere in the Galaxy.

...Of all the proposals put forth to account for the observed Martian phenomena, the idea of life on Mars seems to be the most tenable. And if this idea is accepted, we are immediately drawn to the conclusion that this life is a very well-adapted and flourishing one—not the struggle for existence so often suggested in light of the obvious difficulties earthly organisms would have in living on Mars. The suggested criteria seem to eliminate all the known life forms, but of all these forms, a higher plant would require the least modification in order to meet the criteria. The basic shape of the leaf of a higher plant seems suited to conditions on Mars, but the lower gravity might well result in some interesting modifications in morphology.

Since the mid-20th century, active ongoing research has taken place to look for signs of extraterrestrial life. This encompasses a search for current and historic extraterrestrial life, and a narrower search for extraterrestrial intelligent life. Depending on the category of search, methods range from the analysis of telescope and specimen data[3] to radios used to detect and send communication signals.
The concept of extraterrestrial life, and particularly extraterrestrial intelligence, has had a major cultural impact, chiefly in works of science fiction. Over the years, science fiction has introduced a number of theoretical ideas, each having a wide range of possibilities.

life in the cosmos...The Large UV/Optical/Infrared (LUVOIR) Surveyor is a concept for a powerful general-purpose observatory spanning the far-UV to the near-infrared. Two variants are being studied: LUVOIR-A (15-m diameter primary mirror) and LUVOIR-B (8-m mirror). These powerful and flexible observatories will enable revolutionary new studies in astrophysics and planetary science. LUVOIR is being designed to take the next great leap in exoplanet studies, with direct images and spectra of rocky Earthsized exoplanets in the habitable zones of other stars. These data will allow a wide range of investigations, including analysis of terrestrial planet atmospheres, discovery of potentially habitable exoplanets, and searches for evidence of global biospheres. A key goal for LUVOIR is to conduct these studies on a set of candidate habitable exoplanets large enough to constrain the frequency of habitable conditions (dozens of rocky planets orbiting solar-type stars). LUVOIR will also provide revolutionary advances in a broad range of astrophysics — from the epoch of reionization, through galaxy formation and evolution, to star and planet formation. The observatory could also enable powerful remote sensing observations of Solar System bodies. The LUVOIR-A architecture offers up to 25 km resolution at Jupiter, enabling sensitive, high resolution observations over long time baselines and a broad wavelength range. Finally, perhaps LUVOIR's most important scientific capability is its ability to address not only the science questions of today, but those of the 2040s and beyond that we have not yet thought to ask...

While the bulk abundance of (inorganic) building blocks appears not to be a factor limiting the distribution of life on Earth (with subsurface environments as a possible exception, e.g., Hoehler and Jørgensen, 2013) and, potentially, other planetary bodies, the availability of a solvent is considered to be a key factor. While the potential for other liquid solvents to sustain extraterrestrial life is discussed in detail elsewhere (Schwieterman et al., 2018 and references therein), water is considered the most likely liquid solvent because of its cosmic abundance and physicochemical properties (Michiels et al., 2008; Schwieterman et al., 2018)...

Alien life, such as microorganisms, has been hypothesized to exist in the Solar System and throughout the universe. This hypothesis relies on the vast size and consistent physical laws of the observable universe. According to this argument, made by scientists such as Carl Sagan and Stephen Hawking, as well as notable personalities such as Winston Churchill, it would be improbable for life not to exist somewhere other than Earth. This argument is embodied in the Copernican principle, which states that Earth does not occupy a unique position in the Universe, and the mediocrity principle, which states that there is nothing special about life on Earth. The chemistry of life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the universe was only 10–17 million years old.

Outside the solar system, quite possible!!
But, its confirmation is not easy.
Ys it's possible. On earth we take years to discover it's hidden pieces of regions where persons are surviving so it take time of other planet.... We just imagined such things now.
I am very glad that in our discussion the dominant view is that in our solar system, beyond the planet Earth, there is or once existed life.

Dear Marius Budeanu,
Yes, this is very promising information. In recent years, a great deal of new data and evidence has emerged to suggest that certain simple life forms exist or have existed on some other planets in the Solar System beyond Earth. Perhaps life in certain simple forms came to Earth billions of years ago from space.
Best wishes,
Dariusz Prokopowicz
Its probability is quite high. The presence of the former or existent living creatures will be proven by the occurrence of their trace fossils or life traces first.
Dear Árpád Dávid,
Yes, I also believe that the probability of certain life forms in our solar system beyond the planet Earth is quite high now and / or in the past.

When we think of life, if we do not immediately think of places suitable for our own living conditions, but the environment in which any life can exist, some living things on our planet can have features that can live even on different planets. If hardy creatures such as tardigrades can adapt to different environments, many more undiscovered creatures may have adapted to living in different places in our solar system.
Dear Senem Çabuk,
You added a very interesting and relevant point to our discussion. Yes, the ability to adapt to life in various environments on planet Earth has many forms of living organisms. Therefore, there is a high probability that the analogous adaptability of various other life forms in other exoplanets, in other planetary systems, in other constellations, in other galaxies is equally high.
Thank you, Best wishes,

Now that the American Pentagon officially recognized the UFO's as life from space, there is no end to this story.
Since no one can explain how UFOs travel at astronomical speeds, it will be an exciting subject to investigate at universities with government or Pentagon funding.
If I was younger I would be first to apply for funding.
I think it is possible, the human being has not yet had the possibility to explore the limits of the universe, steps are being taken but the real possibility exists, there are many galaxies with many suns. Although there is always doubt. An important fact about research in this field is that human beings know more information about Mars and other planets than about the oceans and their sea beds. Greetings
Given the size of the solar system and the extent of currently available data on living conditions on individual studied planets, it leads to the conclusion that it is very likely that there is still life elsewhere in the solar system.
“Can there be life somewhere in the Solar System outside Earth?”
- any scientific answer on this question is impossible before the phenomenon/notion “Life” isn’t scientifically defined and elaborated; for what, it turns out to be necessary to define/elaborate scientifically one of utmost fundamental for humans now phenomenon/notion “Consciousness” – and all other fundamental phenomena/notions, though; whereas all fundamental phenomena/notions are fundamentally transcendent/uncertain/irrational in mainstream philosophy and official sciences.
So all what is possible in the mainstream – and so what is in this thread posts, is “I believe that… … ….”, and all these beliefs are completely transcendent.
Including that
“….I also believe it. In addition, more and more data resulting from the conducted research more and more confirms the thesis about a very high level of probability of the occurrence of other forms of life in the universe.…..”
- is rather transcendent proposition, which, though really is experimentally verified, say, an instrument on a planet can find some bacteria, however if nothing will be found, that would not be a proof that Life is possible only on Earth.

Dear Nenad Milosevic,
Thanks for the answer. I am glad that we think similarly regarding the high probability of possible other life forms in our solar system beyond the planet Earth.

The James Webb Telescope is superior to the Hubble Telescope in terms of infrared observations. James Webb Space Telescope - an infrared space telescope built in 2007–2021. In a sense (observing the cosmos only in the infrared range) it is to be the successor to the Hubble Space Telescope. The project, supervised and largely financed by NASA, is being developed in cooperation with ESA and CSA. Thanks to the James Webb telescope, it will be possible to take pictures and study exoplanets in other planetary systems, in other constellations, and to photograph distant galaxies that are up to 13 billion light years away from Earth. Therefore, the James Webb telescope is already referred to as a kind of cosmic time machine. The James Webb Space Telescope is scheduled to orbit the Earth in December 2021. The date of placing this telescope into Earth orbit has been postponed many times since 2007. The construction cost is approximately USD 10 billion. It will be the most powerful telescope ever built by man, and it will be placed in the Earth's orbit.

Extraterrestrial life is hypothetical life that may occur outside Earth and which did not originate on Earth. Such life might range from simple prokaryotes (or comparable life forms) to intelligent beings and even sapient beings, possibly bringing forth civilizations that might be far more advanced than humanity.
Life in space is very likely but millions of light years outside our solar system. On Mars, it may have existed once when there was water on Mars. ... Perhaps life exists in the oceans under the ice on one of the moons of Jupiter, i.e. called Europe (Jupiter II).
Except earth, there is no significant evidence of life in our solar system.
Dear Faraed Salman,
Yes, that's right. Extraterrestrial life is still a great mystery.

Dear Colleagues and Friends from the Research Gate portal,
The image presented by NASA shows the result of a study of the composition of the atmosphere of exoplanet WASP-96b. It is one of the first images published on 12.7.2022 and taken thanks to the state-of-the-art James Webb Space Super Telescope located in Earth's orbit. The image shows a graphic depiction of the results of the WASP-96b NASA/ESA/CSA/STScI measurement of the composition of the exoplanet's atmosphere. Through this image, NASA has shown the result of the extremely sensitive instruments found on the James Webb Telescope. The image shows the most accurate measurements to date of the composition of the atmosphere of an exoplanet, or planet, located outside the Solar System. The exoplanet whose atmosphere the telescope has studied is WASP-96 b, a gas giant located just beyond the edge of the Solar System, at a distance of about 1,100 light years from Earth. It is particularly interesting that the telescope detected, among other things, noticeable traces of water in the studied composition of the exoplanet's atmosphere! The collected data also suggest that the atmosphere of this celestial body contains water vapour and clouds. So, we are probably gradually approaching research results which will confirm that, with a high level of probability, there is water, Earth-like environmental and climatic conditions and some form of life on many exoplanets located many thousands and millions of light years from our Solar System.
Best regards,

Probably yes! but still we don't have any clear evidence for this to say yes!. and within solar system still we have not received any mysterious radio signals from the planet.
There could be life somewhere in the Solar System outside Earth. Scientists have found evidence of water on Mars and Europa, one of Jupiter’s moons. Water is a key ingredient for life as we know it. There are also other moons in the Solar System that could potentially harbor life.
It does seem that there might be, but I don't know if we want it to visit us on Earth. We have enough home grown unrest without anything else upsetting us!
