Could super earth host life?

An artist's illustration of the view. From the exoplanet LHS 1140b. That giant orbits an M dwarf star about one-fifth the size of the sun. 

The planet could be a prime target for follow-up studies in the search for life elsewhere in the universe. (Image credit: M. Weiss/CfA )(Astronomy.com/Newfound Alien Planet Is Best Place Yet to Search for Life). 

Water is fairly common in the universe. But the problem is that life needs liquid water. There are some models that in the water droplets of the vapor in the atmosphere of the hot planets can form the RNA molecules. In that case, the water droplets with RNA could be the most primitive organisms that we can imagine. Those hypothetical organisms would be only the RNA bites and organelle in the water droplet that can copy itself. 

The mass of that exoplanet is about 6,6 times Earth, and the size of it is about 1,4 times of Earth. There are calculations that this 6,6 Earth mass is the limit of the mass of the planet. That can host life. 

Super earth of giant rocky planets orbiting very close to red dwarf stars is causing discussions about alien life. There is the possibility some of those super earth have liquid water on their surface. There is the possibility that also yellow stars have super earth. 

Researching those super earth that are orbiting red dwarfs is giving data that can use to make models about the lifeforms of planets that are more similar to Earth. The idea is that life is almost always born in oceans or underwater conditions. 

Even if organisms on planets around red dwarfs remain at primitive level or underwater conditions there is the possibility, that there is a similar planet orbiting some yellow star. And the life forms on that super earth would turn more advanced, creating even civilization. 

And that always causes discussions about the lifeforms that could live on those planets. Those rocky worlds are locked, but vaporizing water from oceans can make those planets' surface temperature low, and freezing night-side of the planet will also lower the surface temperature. So could there be some lifeforms? 

Even if the dry land areas on those planets are hostile to lifeforms. There is a possibility that some kind of alien organisms can live in their oceans. When we are talking about alien life, we must realize that intelligent alien life is a different thing than alien life. There is the possibility. Primitive organisms like bacteria can live on many planets. 

But intelligent aliens are a little bit different thing. They might not be as common as some bacteria or algae. The water worlds or planets that are covered by water layers can host some primitive lifeforms. 

There is one thing that we must realize. That thing is that there could be lifeforms in the oceans. But those lifeforms might not able to rise to drylands. So there could be some algae or even fish-type alien organisms on those planets. 

The water layer protects those animals against the heat of the eruption of the red dwarf. The organisms that live in the alien planet's oceans can exist even close to deadly radiation sources. The water layer is a good protector against the radiation that comes from neutron stars or black holes. 

But the thing is that intelligent lifeforms need some other conditions. In all models technically advanced civilization requires the ability to live and operate in dry lands. All models that are made of alien lifeforms are models. Nobody saw those lifeforms yet. Or there is no concrete evidence that certain planets are hosting life. 

Silurian hypothesis: are aliens visited on Earth? The fact is we don't know. 

There is a so-called "Silurian hypothesis" about the ancient alien visitors to Earth. The evidence of those things is weak. And nobody can say 100% surely are those visitors true or false. And that's why they are under research. Those pieces of evidence are the Egyptian and Mayan artifacts and things like Nazca lines. 

And the artifact on the walls of some cathedrals, along with folk stories like American Indian and Buddhist stories of the blond-hair gods or warriors, give some kind of possibility that some kind of alien visit to Earth is possible. But the "smoking gun" evidence is missing. There is no concrete proof that some nation has alien bodies. Or the existence of those bodies wanted to deny. 

There are a couple of signals like Wow! and BLC1. The origin of the BLC-1 is in the direction of Proxima Centauri. 

The Wow! signal was captured by the "Big Ear" telescope. And the BLC-1 was captured by the Australian Parkes observatory. 

The programmer of the computer forgot to determine which of those two antennas are receiving the transmission. But astronomers calculated the origin of that signal for both antennas. So there are two possible directions where the "Wow! signal" can come. And in another direction is a Sun-like star 3000 light years from us. 

The origin of those signals can be in intelligent civilizations. But the fact is that those signals are captured only once. That makes mystery. There are opinions that the natural source of those signs requires that those signals are repeating or that the chemical compound of those transmitters should be unique. 

The thing is that the "Silurian hypothesis" is one of the versions of the theory that somewhere in our universe is an intelligent civilization. Or in the universe, there must be intelligent civilizations. There are billions of galaxies in the universe and we would be too lucky if we are alone. But how close are those civilizations? 

That thing remains a mystery. Until the first confirmed data transmission comes from another star. And, of course, we must realize that the origin of the data transmission must not necessarily come from endemic species. The source of those signals can be the alien outpost. Or it can be a man-made satellite. Without repeating. The source of those mysterious Wow! and BLC-1 signals remains a mystery.

A new exoplanet found near Proxima Centauri

"This artist’s impression shows a close-up view of Proxima d, a planet candidate recently found orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System. The planet is believed to be rocky and to have a mass of about a quarter of Earth. Two other planets known to orbit Proxima Centauri are visible in the image too: Proxima b, a planet with about the same mass as Earth that orbits the star every 11 days and is within the habitable zone, and candidate Proxima c, which is on a longer five-year orbit around the star. Credit: ESO/L. Calçada "(ScitechDaily/New Planet Detected Nearby – Orbiting Around Star Closest to the Sun)

This is one of the most amazing things in history. A new exoplanet has found the star system that is closest to our Sun. It's also the lightest found exoplanet. 

The planet is named Proxima d and that is one of the biggest things in history. That planet is not confirmed yet.  The distance between the Sun and Proxima Centauri is about 4,25 light-years. And that means that the star is very close to us. And the new exoplanet is telling that there are lots of things to find even close to our sun. 

Proxima Centauri is a red dwarf star that orbits the Alpha Centauri system. There are already two known planets orbiting that star. And that means there could be more exoplanets in the Alpha Centauri system. Probably the James Webb telescope can find the first exoplanet. That orbits the Alpha Centauri itself. The Proxima Centauri or Alpha Centauri C is much smaller to our sun. But it's heavier than Jupiter. And that means it could "steal" planets from Alpha Centauri. 

Computers detected Proxima b from old data of the Hubble telescope. And that thing means that there might be lots of data that involves many interesting things. The detection of those planets happened in 2016 and 2020. 

When we compare that thing with the Gliese 581 system. We might wonder why astronomers found Gliese 581 planetary system in 2010? The distance between Earth and Gliese 581 is 20 light-years. So why the exoplanets that locate 4,25 light-years are harder to detect than those exoplanets of the Gliese system? 

Does the brightness of the Alpha Centauri system cover those planets? The fact is that those exoplanets are fascinating. And there is the possibility that there is some kind of primitive lifeforms on those planets. Those organisms might be like some kind of fungus that lives at the border of light and darkness at those locked planets. But that is only vision.

The most exotic world in the Universe: PSR B1257+12 known as "Poltergeist"

 

Image: Artist's impression of "Poltergeist". The radiation of pulsar melts the dayside to liquid stone. And that planet would be sterile and one of the most hostile worlds in the Universe. 

The most exotic planet in the known universe is PSR B1257+12. Also known as "Poltergeist". The "Poltergeist" is the first found exoplanet And it orbits a pulsar PSR B1257+12 named "Lich". That exoplanet is a member of a three planet system. 

Those planets are Under powerful radio and particle radiation. The source of that radiation is in the pulsar. The fact is that powerful radio impulses would make the surface of "Poltergeist" one of the most frightening and unusual things in the known Universe. 

x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x

The SETI. And visions of the singularity of consciousness of the alien species.

The surface of "Poltergeist" is sterile. The pulsar will sterilize it. But it has brought a couple of visions about the possibilities of the powerful magnetic fields. "Poltergeist" is the planet that brought some interesting visions into the minds of researchers. One of the things is the hypothetical "Poltergeist creature". 

The idea of the "Poltergeist-creature is like the game of imagination. If some creature could live on that planet it might have a "Jedi force". That means this hypothetical creature could channel the powerful magnetic fields through its nervous system. So if that creature would be in an extremely high technical state. 

That thing could pump energy to its nervous system by using a superpositioned and entangled particle pair. So the creature would be the identical twin. The other part of twins is at "Poltergeist". And then that creature will transmit energy to the nervous system of another part of the twins. But that is only the hypothesis or philosophical model. 

That intelligent species at the surface of "Poltergeist" might not exist. But those visions about the singularity of minds are interesting. 

If the intelligent species would land on the surface of that planet the mind of those hypothetical creatures would turn into a collective singularity. The strong magnetic field will act as the carrier wave. And that turns the organisms into one entirety. 

The SETI researchers have created a hypothesis that the EEG of intelligent humanoids can collect by using radio telescopes. When radio waves of the pulsar travel through the brains of hypothetical aliens. 

That radio transmission acts as carrier waves. The alien EEG causes errors in the radio transmission. So, astronomers can detect those errors or changes from Earth by using radio telescopes. But how to separate those EEG curves from the natural radio transmission from pulsars is a little bit problematic. The fact is that nobody knows what the alien EEG should look like. 

If there would be some intelligent species at the surface of the "Poltergeist" they would not need any other energy source. The radio antennas can bring enough electricity to the technological advantages of that hypothetical civilization. The pulsar will sterilize the surface of "Poltergeist". And that means it's hostile for lifeforms. 

x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x

The "Poltergeist" can give information about how planets are forming. 

The "Poltergeist" is suspected to be the so-called post-stellar planet that formed from the supernova remnant of the "Lich" pulsar. The fact is that. Also, all other planets are forming of material that formed in some supernova explosions. But "Poltergeist" is probably formed from the dust. That material formed when the "Lich" exploded as a supernova. 

Before rocky planets can form the interplanetary nebula must have the elements that are forming rocky planets. Every single element in the universe is formed in stars except hydrogen. Elements like uranium and other very heavy elements form only when the largest stars in the universe are exploding. The fusion reaction in the stars is the source of all elements in the universe. 

And forming of the superheavy elements requires extremely or precise size stars. All uranium that is on Earth is a remnant of the ancient supernova.  

 The star should have a precise mass when it explodes is simple.  is if the star is too heavy. It turns into a black hole during the supernova explosion. If the star turns into a black hole during a supernova explosion. There is the possibility that the entire material that it releases is dropping back to it. 

The forming of a black hole begins in the center of the star. The explosion of the collapsing star causes giant fusion that presses the material to singularity. The event horizon is starting to expand and if the size of the star is high enough the event horizon that expands with the speed of light will reach the escaping material and close it inside the black hole. 

The speed of expansion of the gas bubble around the supernova is always slower than the speed of light. The expanding event horizon will always reach material. Because of the expansion of the event horizon reach a speed of light.  So it closes the material bubble inside it. And that thing will make the effect of the disappearing star.

The most extreme exoplanet has been found near Beta Centauri.

   The most extreme exoplanet has been found near Beta Centauri.

"This artist’s impression shows a close-up of the planet b Centauri b, which orbits a binary system with mass at least six times that of the Sun. This is the most massive and hottest planet-hosting star system found to date. The planet is ten times as massive as Jupiter and orbits the two-star system at 100 times the distance Jupiter orbits the Sun. Credit: ESO/L. Calçada" (https://scitechdaily.com/surprise-planet-discovered-around-extreme-star-pair/)

The Beta Centauri is the second brightest star in the Centauri constellation. The brightest star of that constellation is Alpha Centauri. 

The Beta Centauri (Beta Cent or Hadar) is a two-star system that has at least three components two stars and one planet. The members of this system are Beta Centauri Aa, Beta Centauri Ab, and Beta Centauri B. There is only one member of this system Beta Centauri A which has confirmed spectral type. 

That bight Beta Centauri Aa has a spectral class B1 III.  And that means the star is extremely bright. That brightness will make the Beta Centauri B disappear. The exoplanet that orbits in this system is so-called hot Jupiter. The observation is made by using ESO (European Southern Observatory). And that is the first case, where an exoplanet is found near extremely bright stars. 

The strong X-ray emission from the atmosphere of an exoplanet is the thing that uncovers the existence of Beta Centauri Bb. Which orbits the Beta Centauri 100 times more distant than Jupiter orbits the Sun. 

This means also exoplanets are forming X-ray emissions. The exoplanets that are orbiting bright stars are in the situation, that the high-energy electrons and ions are impacting their atmosphere. And that thing makes the exoplanets visible in X-ray images. 

The new exoplanet Beta Centauri Bb Is an example that also bright double stars.  Or stars, where are multiple members in the system, can have planets. The planet of Beta Centauri is extremely hostile to lifeforms, but it's the evidence that also other than lone stars can have planetary systems. 

The thing is that the exoplanets are very interesting targets for astronomers. They can have lifeforms and maybe someday astronomers can find the intelligent alien species on those planets. The thing is that there is the possibility that the Beta Centauri Bb is not formed in the system of Beta Centauri. It could be a rogue planet that is trapped in the gravity field of Beta Centauri.

This image shows the most massive planet-hosting star pair to date, b Centaur

"This image shows the most massive planet-hosting star pair to date, b Centauri, and its giant planet b Centauri b. This is the first time astronomers have directly observed a planet orbiting a star pair this massive and hot. The star pair, which has a total mass of at least six times that of the Sun, is the bright object in the top left corner of the image, the bright and dark rings around it being optical artifacts".

"The planet, visible as a bright dot in the lower right of the frame, is ten times as massive as Jupiter and orbits the pair at 100 times the distance Jupiter orbits the Sun. The other bright dot in the image (top right.) Is a background star. By taking different images at different times, astronomers were able to distinguish the planet from the background stars"

"The image captured by the SPHERE instrument. On ESO’s Very Large Telescope and using a coronagraph. Which blocked the light from the massive star system and allowed astronomers to detect the faint planet.
