James Webb telescope took its first direct exoplanet image.



"The HIP 65426 b gas giant planet photographed by the James Webb Space Telescope on the background of the Digitized Sky Survey (Image credit: NASA/ESA/CSA, A Carter (UCSC), the ERS 1386 team, and A. Pagan (STScI))(Space. com/James Webb Space Telescope snags its 1st direct photo of an alien world)

JWST telescope took the first image of an exoplanet. That exoplanet is HIP 65426 b, the gas giant 348 light years from Earth and located in the constellation Centaurus. 

The HIP 65426 b is carbon-poor. But an oxygen-rich version of "our" gas giants. The exoplanets are named similarly to their binary star. But there is a letter b or c, etc. behind that name. 

The binary star HIP 65426 is spectral type A2V and its color is blue. The surface temperature of that star is about 7500-10 000 kelvin. The surface temperature of the sun is about 5778 K. The HIP 65426 burns its fuel very fast. And this means the lifetime of HIP 65426 is not so long, that there can form some kind of intelligent and technically advanced civilization. But the HIP 65426 b is otherwise a very interesting object. 

Maybe later we will get better images of the Proxima Centauri b. And there is the possibility that the JWST can find some kind of alien life from some planets. The HIP 65426 b is a harder target than Proxima b. Its binary star is much brighter. And the distance to that star is much longer than to Proxima b, which is about 4 light-years from Earth. 

Maybe JWST finds more exoplanets and uncovers their moons. And there is the possibility that JWST will solve the mystery of the existence of Gliese 581 g and d in that multiplanet solar system that orbits the M3-class red dwarf 20 light years from Earth in the Libra constellation.

James Webb-telescope detected carbon dioxide in the exoplanet's atmosphere.



Above: Artists' impression of exoplanet Wasp-39B


Exoplanet Wasp-39b has carbon dioxide in its atmosphere. That thing is one of the possible marks of the lifeforms. But there is also the possibility that oxygen is connecting to carbon in the atmosphere of Wasp-39b. The Wasp-39b is a giant exoplanet. It's so-called hot Jupiter and the atmospheric temperature of that planet is 900 degrees Celsius. That is an extremely hot planet, so there should not be any lifeforms. 

But there is one possibility that is not what somebody wants to hear. The possibility is that the carbon dioxide is coming from the high atmosphere of some invisible target near Wasp-39b. The object can be some kind of moon near Wasp-39b. There is also water (H2O) and sodium (Na) in that planet's atmosphere. 

The Wasp-39b orbits its central star in four days. The mass of the Wasp-39b is one-quarter of Jupiter. So its mass is similar to Saturn but the size is larger than Jupiter. The reason for that is that the Wasp-39B is forming of lighter elements than Jupiter. And that means it's lighter but 1,3 times bigger than Jupiter. The question is why Wasp-39b doesn't lose its atmosphere to its star G-class star Wasp-39 ("Malmok"). That star is slightly smaller than our Sun.  




The Wasp-39b orbit time around its star is 4 days. So why Wasp-39 didn't burn that planet to an interplanetary cloud? Why Wasp-39's star wind of ions doesn't blow the Wasp-39b to space? The gravitation on Wasp-39b is not so powerful that it could keep that gas giant in one piece. And Wasp-39 is not any red dwarf. It's quite similar to our sun. 

So some people say that Wasp-39 b should not even exist. Many other exoplanets are orbiting their center star in a couple of days. But those planets are orbiting red dwarfs whose surface temperature is about 3500 celsius. Wasp-39's surface temperature is about 5000-6000K (about 4726-5726 degrees Celsius) (The temperature of the Sun's photosphere is 5772K)

There is the possibility that there is another small dwarf or so-called real planet in those solar systems. Even Earth-mass rocky planets are hard to detect if their size is very small. If the earth-mass planet forms mainly of heavier elements like iron and other heavy metals that thing means that its size is smaller than Earth if its gravitation is the same as Earth.

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.

There is a possible planet outside the Milky Way



The founding of the exoplanet candidate from the other galaxy is not very surprising. The thing is that other galaxies are similar to Milky Way. And that means there must be solar systems and planets like in our galaxy. 

That means the universe is "full of planets" and we are just waiting to find a planet that can have lifeforms. The most feared moment is when we are first making contact with other civilizations. That time will be someday in the future. Even we would be alone in our galaxy, there is the possibility that there are other intelligent species in other galaxies. 


The visions of the future of the human race


And now I will explain why I believe that someday the human race will meat aliens. Even there is no other intelligent species other than humans in our Galaxy there is the possibility. That someday in the future we are moving to space and other planets. 

In the future, the human race will travel to our solar system. And during that project, the goal would be the case that some colonists are born and die in the colonies. The thing is that those colonists are sooner or later stopped to keep in contact with their families. Maybe the persons who are moving to the colonies from the Earth will keep in contact. But for people who were born in colonies would never see Earth. 

In some visions, the evolution would form the creature called "Homo Sapiens Spaces". In that vision. Some people would spend their entire life in zero-gravity conditions. In that case, the muscles and bones of those people are turning weak. And if that thing happens. Those people who were born in space stations that have no artificial gravitation would crush in gravitation fields. 





"Solar Warden" is the hypothetical station in which zero-gravitation conditions make crew unable to return. 


That idea is an origin for the conspiracy theory that the genetically engineered engineers would put to live in the space station. That environment makes it easy to control those people. That crew could communicate with computers by using a brain control interface. 

And those crews could connect to the entirety with each other and central computer. So that a hypothetical space station can use as the data handling center. In that system, the brains of the crew and central computers will be acting as an entirety. 

So those people cannot ever land on planets. The same thing happens if the crew of the space station stays too long in that place. So that's why artificial gravitation is necessary for space stations and long-term space journeys if we want to get crew back to Earth. 

During those journeys, our descendants need very advanced bio- and genetic engineering. For making the colonists fit their new home planets. That kind of thing makes the colonists aliens to other colonists. That means that the colonists who are genetically engineered for their environment might not even look like being members of the same species that have conquered the entire galaxy. 

But if that kind of thing is the future of mankind we must say that we are a little bit too lucky. In that kind of situation, we would be the luckiest civilization in the entire universe.
