There is a possibility. That astronomer found the first planet that orbits 3 stars.

 

Image: I: The anomaly in dust disk around GW Orionis

The star is GW Orionis. Distance to that star is 1300 light-years. The planet itself is not visible. The system that has made that detection is ALMA (Atacama Large Millimeter/submillimeter Array). And the researchers worked for Nevada State University. The following months will confirm or not confirm that observation. 

The planet itself is not visible. But that object causes an anomaly in the dust that orbits the central stars. And the planet can be seen because of that anomaly. The straight observations of exoplanets are hard to get. 

But non-straight observations like changes in the brightness of the stars or the gravitational interaction between planet and dust are also visible. The gravitational interaction between the planet and the dust requires that the dust disk is visible.  

The change of the brightness of the stars is a good method to track the exoplanets. But that requires that the planet travels between Earth and that star. The last method can use also with distant objects.

And that is the thing that might confirm the scenario that the planetary systems are more common than astronomers expect. In the universe are confirmed exoplanets that are orbiting multi-stellar systems. The most well-known of those planets is Proxima Centauri B. That planet orbits the red dwarf at the closest stellar system Alpha Centauri. In those cases, the exoplanet is orbiting the distant member of the multi-stellar entirety. 

Those distant members of the triple- or multi-stellar systems are offering the possibility for their solar system. In those cases, the multi-stellar system is "open". The distant member of the entirety has its planetary system as Proxima Centauri has. But in another case, there is the possibility that the triple-star system is "closed". In that case those central stars are are very close to each other. And the planets can orbit them as the entirety. 

When we are thinking about the possibility that planets are forming around the triple-star system there is lots of dust and other particles around those stars. That means that there could be forming planets around them. But the other version of the form of the planetary system is that the stars or multi-stars are capturing the rogue planets. 

The common gravitational effect of the multi-stellar systems is huge. And that means that kind of solar system can pull objects from great distances. The thing is that this finding was a great step for science. Stars are bright things. They are covering planets in their shine. The thing is that the existence of planets doesn't mean that there are lifeforms in the solar system.

The grey aliens and the Hydrogen-Ocean (Hycean) planets are interesting topics for discussions about alien lifeforms.

Can the grey color of the mysterious "Grey aliens" be the brains of the creature? 

Cosmobiology researchers have introduced that some intelligent aliens have their brains in the skin. The idea is that the grey skin of the mysterious alien creatures is the intelligent fungus. That means the brains of those aliens would be their skin.

There is one interesting theory about the "Grey aliens". The idea is that the "grey skin" of those creatures is the thinking part. Or the brains of that mysterious creature. In that vision, the grey skin would be the brains. That is interacting with a body that it uses.

So in this part of writing the idea is that "Grey skin aliens" are somehow true. Or even if they are not true they can give models for thinking what the intelligent alien creatures might look like. 

And the conclusion is that maybe there is the possibility that the alien creatures have thinking skins. The intelligent fungus is covering their bodies and controls them. The "grey aliens" are used as the model, what kind of intelligent alien creatures can have intelligent skins. But let's go to think about the primitive alien creatures, that might live in the oceans of giant water-covered planets.

The Hycean planets can support life. 

The Hydrogen-Ocean or "Hycean planets" are giant, water-covered exoplanets with a thick hydrogen-based atmosphere. Some of those planets are orbiting their sun so close that they are locked. And the temperature on the dayside can be over 200 degrees celsius. The idea is that the ocean which depth can be hundreds of kilometers would not be so hot in depth. And the nightside will also decrease the temperature of the water. So maybe in those oceans is the living creatures. 

The clouds of steam that are rising from the oceans can decrease the temperature in the oceans. And the creatures that are living in those oceans are fully adapted to that environment. 

What kind of creatures those hypothetical and primitive alien species could be? Can they use photosynthesis or maybe the temperature of the extremely hot ocean for energy production?

The lifeforms can be algae or some other type of amoebas. There is the possibility that the algae are positioned to the bottom of the extremely deep ocean. And they might send the short-living cells to the surface. Those cells can produce oxygen and then they can store that oxygen in the vesicle that will fall back to the ocean for the food of that algae. The other version of these hypothetical lifeforms is algae or polyps. They have long tentacles that they will push to the surface of the ocean. 

The ends of those tentacles will burn, but they have enough time to create photosynthesis. Or those creatures might use the temperature of the hot ocean for making energy for them. Similar organisms have been met near "black smokers" at the bottom of the ocean on Earth. So why the hypothetical alien lifeform cannot benefit the temperature of the hot ocean as energy production? 

But when we are thinking about the form of the hypothetical alien creatures we must remember that we cannot close any possibility out before we are seeing those creatures. We know that the cells can resist high temperatures. One version is that the cell is covering itself by using slime. The slime isolates it from the hot water. Or maybe those cells are dividing so fast that the hot water cannot burn their genomes.

Why Tau Ceti and Epsilon Eridani was selected to target for Ozma message?

Why Tau Ceti and Epsilon Eridani was selected to target for Ozma message?

The "Project Ozma" (1)from the year 1960 was the first attempt to make contact with other civilizations. It was the pilot experiment for the SETI (2)-program and another kind of interesting stuff. When this program was failed to making the contact, that means that things like searching the exoplanets got the scientific basement, and at that time, we didn't have a single observation of the exoplanet. Today we know thousands of exoplanets, and maybe we would make contact with another civilization. 

The famous "Ozma" message to another star was sent to Tau Ceti (3) and Epsilon Eridani (4). The attempt was to make contact with super civilizations, and the idea was that those stars and their solar systems were so different than our own that those civilizations would not threaten us. If the solar system would not have oxygen, there would be no water and the "Ozma" researchers thought that they could find the civilization, what would be the silicon-based, what means that the hypothetical civilization would not even want to land on our planet. 

Epsilon Eridani was another object, where the scientists send so-called "Ozma-Message". The thing is that the Epsilon Eridani is too young to be the home of the advanced civilization is putting brakes to those people's operations, who are working with SETI-program. 

And sometimes people would ask, why those researchers selected the Epsilon Eridani to target for "Ozma-message"? The star was too young for the intelligent civilization, and the answer would not even be hoped to get.

If the answer to Ozma-message would come near the young star, that means the answerer is the colony of a very advanced civilization. "Ozma" was projected, what mission was to look for intelligent and advanced civilizations. And it was the pathfinder for a modern way to make science. Today we know that most of the stars might have some kind of planets around them, and the thank to this thing would belong to the "Ozma"-team. 

The dust and ice makes difficult to see the planets near Epsilon Eridani

They opened the eyes of the people to see, that there would be something, that we don't know. In modern times the way to make science is that the team would research and make observations before we would not laugh or punch anybody. The thing is that the Tau Ceti, Epsilon Eridani, and Alpha Centauri have at least suspected planets orbiting them. And the Tau Ceti and Alpha Centauri (5) have confirmed planets, and Epsilon Eridani has suspected followers. The disk of dust and ice makes difficult to see planets, what are orbiting it.

So the answer is that the scientists thought that if the answer for those messages would come from Epsilon Eridani, the hypothetical answer to out message would come from the transmitter from the very advanced civilization. This hypothetical civilization had the technology, which allows them to create colonies to another star system. 

And if the answer would come near the young star, that must be the colony, what will answer to the message, what the scientists have sent. The target stars would be carefully selected, because "Ozma" was looking for intelligent and advanced civilizations. So the thing, what those people had to find was the star, where is no planet, what has endemic lifeforms.

The hottest exoplanet in the universe

The hottest exoplanet in the universe

Extreme exoplanets are a good source for making interesting theories about the other exoplanets and their role in the planetary systems and even the bearer of lifeforms, which might be very primitive. The hottest known exoplanet KELT9b has a strange meteorological phenomenon, where the rising gas pylon causes the situation, that the atmosphere is heating in ultra-hot temperature. The temperature of an atmosphere of that planet is hotter than the star, what it orbits. 

This strange world might not have any lifeforms, because it's like some hot Jupiter. In some scenarios, this kind of planet would have the gas-geyser in the atmosphere, and that kind of thing allows that the gas from the atmosphere would not flee to the universe or central star of that system. 

In this kind of scenario, the gas would rise to upwards and when gas layers and dust are touching together the temperature of that planet's atmosphere would raise extremely hot because of friction, which would turn the planet extremely hot. If the distance of the planet to the central star is high enough the gas would drop back to the atmosphere.  

But if the planet is too close, that gas would be sucked to the star. If the planet would consist of the heavy elements, that distance can be quite small, and if the entire planet would be made by Crypton, that would be a very heavy object, because element or noble gas Crypton is the heaviest stable element on nature. And if that element forms the Jupiter-size object, that would have an extremely high power gravity field, because that element is so heavy, but the question is "could the noble gas form the planet?". 

That thing has caused the thoughts that are it possible that some planet a similar phenomenon would make the planet, which is a very long distance away from the central star's ability to have liquid water. The theory of this phenomenon has caused because there is a possibility that the friction between the gas layers in the planet atmosphere would make it possible that the temperature on the surface of that planet would allow the existence of liquid water. 

That doesn't mean that there could be any kind of animal or other life forms, except the primitive bacteria, which would live in the water. Those hypothetical organisms get their energy from volcanic heat. In this case, the upper atmosphere of this hypothetical planet would shine in the extremely high temperature, and the friction would shine heat to the surface of that planet. 

The reason why the higher life forms would not probably live on that yet fictional planet would be that the distance between that planet and the central star could be so big, that the radiation of that star would be extremely low, and that's why photosynthesis would not be possible. In some other theories or scenarios, the fast-rotating atmosphere of the planet would melt its entire lithosphere. 

If the planet would have that thing, and then the heated atmosphere would work as the sun for some moons, which is orbiting that planet. The idea is that in this kind of cases the moons of this kind of extreme hot planet would be habitable if their atmosphere would be stable.

The planet of water drops

The planet of water drops

The "water drop alien" (or robot) is mentioned in one book, and the thing is that this kind of organism is not so imaginational as we might want to believe. One version of those things is the structure, which seems a little bit like sea-urchin. This structure would have long cilium, which keeps the water above it, and the water makes the protective core for the body of the organism.

Or actually, it might seem like the fluff and the kinetic particle would be inside the water drop. If we are thinking about the alien, what wants to move the fetus in the stomach of some other organism, it can simply create this kind of semen. The mission of the water drop is to deny the operations of the detectors, what mission is to warn the living organisms about the bio danger. And that kinetic semen might be transparent.

Here we must realize that those things might be systems, what mission is to transfer the nerve cells to the body of the other species. So if they are artificial, they might be creatures, that are created by using highly advanced bio- and robotics technology, and they might be very deadly systems. The thing is that those machines could make the layer between the brain core and the inner brains, and that allows taking the body to the control. Or they just can release the morula to the stomach, of the creature, what eats them. So this kind of thing is really dangerous, and that would give breaks for the plans of the journeys to the other solar systems.

Do you know, why I'm talking about structure? The thing is that when we are talking about exobiological systems, we might also mean things like automatized factories, what are left on the planet when living organisms have been gone somewhere. In this case, the hypothetical aliens would simply fill the water storages and make repairments in the solar system before they would continue their journey.

So if we are thinking about the case that some alien civilization could make the base to some water planet that thing means that some kind of systems like "Von Neumann" factories might be below the surface, and if rescue crew doesn't know about them, they can leave those robot factories below the surface. In this case, the robot factories would continue their mission.  Or the aliens would just forget to cut the power when they are disbanding their systems to some planet.

But this kind of system is also interested in the military because that kind of thing allows delivering poisonous material like nerve gas to some bases. In those cases, this kind of hairy ball robots would transfer the nerve agent to the military base, and sensors would not be alarmed, because those systems would be covered by water. And when the water drop is drying those robots would release the poisonous agent in air.

Artificial intelligence and water covered planets and their influence on science

Artificial intelligence and water covered planets and their influence on science

Artificial intelligence and brightness of the stars

Artificial intelligence can follow the changes in the brightness of the objects, and that system can also connect every data, what has ever collected from some area in the Universe. That allows seeing also the short term changes in the brightness of certain stars in giant star clusters, even the astronomers cannot separate one single target from the cluster of thousands of stars.

Those changes in brightness would take only a couple of minutes, and the period between the eruptions can be years. The artificial intelligence would observe multiple targets at the same time by collecting all data, what is collected from some area by using telescopes, what are different sides of Earth.

That would help to choose targets for planet hunters, where they can turn their extreme large telescopes. The thing how the search the planets is done is similar, what is used in the hunt of asteroids. The smaller telescopes are taking images, where is seen multiple stars, and then the system waits for the change of the brightness, or make spectroscopic analysis with multiple stars in the same time, what makes possible to use water maser emission in the multiple stars.

The emission happens, when the star would tune hydrogen and oxygen atoms to send the radiation with their frequency, that means that there could be a habitable planet orbiting that star. But the thing is that also water worlds are giving that kind of emission, and the thing is that the water covered planets might have an atmosphere, what is poisonous for humans. The water worlds would maintain the lifeforms, what might look like fish or some other water animals.

Water planets and SETI (Search for Extraterrestrial Intelligence) program

The thing in those water worlds is that some of them might have islands. And another thing is that if the planet covers by the giant oceans, those sea areas will make it cooler. The star would cause the forming of the clouds, and that cloud layer effectively absorbs the radiation, what comes from the star. This means that the water planet might locate near the center star. And there could be mountains what would form islands. So what if there would be intelligent lifeforms. Could they be curious, and climb to some of those islands, and would they have the ability to use suits, where is the oxygenizing system?

If we think that those aliens would need weapons in raising of drylands, they might just open the water tanks below the surface. Then when they open the ventilates, the water impulse would hit the target. And as you might notice, this is the topic in many SciFi tales thing straight from Hollywood, where every explorer must have guns. Those things make possible to put a little bit more action in those films.

But let's go back to topics. When we are thinking about intelligent civilization, what could be the lifeform, what is living in the sea, we must remember that intelligence is an ultimate tool for creatures, what might have gills. That thing might give limits for their life on the dry land, but there is a possibility, that those hypothetical aliens would use the inverse versions of the diving suit. In this hypothetical case, the alien would simply create the suit, what is filled with water, and that allows them to operate on the drylands, and create the artificial fire.

Of course, they could benefit the volcanic eruption holes for creating metals. But if we think the intelligent civilizations and creatures, maybe they would be curious. That means those underwater aliens would make the explorations to the drylands, and then they can fly to space by using spacecraft, what cabin will be filled with water. That kind of hypothesis is a really interesting way to spend time in the nice morning.
