Device settingsongoing, and we should wait until the summer before the real scientific research begins. However, we have seen that the first image published showing as well as in the background after the first setup of all hexagonal shape, was already spectacular in terms of .
We quickly verify this by comparing this image with the image of the same star and the same region of the sky observedto whom we owe many discoveries in the field .
This is not surprising since the JWST has a collecting surface seven times that of the HST and was expected to be 100 times more sensitive than previous infrared (1 to 27°) space telescopes. .from ) as Iras, as well as .
Therefore, we will not be surprised by rumors circulating about already intriguing and potentially revolutionary observations that will start to appear as a result of processing other observed targets to enable the use of JWST tools, such as MIRI (Middle infrared instrument), produced by a European consortium under the auspices ofwhich will work in the mid-infrared (or thermal, i.e. in spectrum 5 – 28 μm), to which CEA and Cnes contributed.
The observations in question would have a disturbing interpretation if one accepted the calculations and ideas proposed in the late 1960s by twooriginal and whose reputation is firmly attached to one of them, because he great exobiologist-innovator . Actually the father was from the Khmelnitsky region in the territory of modern Western Ukraine.
Iosif Chklovsky, Soviet Carl Sagan
The other astronomer, like many brilliant researchers of the Soviet era, is certainly unknown to the general European public, and yet he is the Soviet Sagan as far as the Set program is concerned. This is Iosif Chklovsky, born on 1uh July 1916 in Glukhov, Sumy region of Ukraine, died March 3, 1985
As astronomer Kirill Maslennikov explains in the video below, Chklovsky made a name for himself by first correctly interpreting the origin of Earth’s radiation.namely production synchrotron ultrarelativists moving along a line his central. But, as you can see from the same video, his contributions and ideas go far beyond, be it where .
One of the very interesting popular videos of astronomer Kirill Maslennikov, filmed at the famous Pulkovo Astronomical Observatory, located south of St. Petersburg. It is dedicated to the contribution of Joseph Chklovsky. For a fairly accurate French translation, click on the white box in the lower right corner. After that, subtitles in Russian should appear.

Iosif Chklovsky was a radio astronomer, as wasand his colleague and collaborator also actively involved in the equivalent of the Network program in Soviet Russia and to whom we owe the famous classification of civilizations in consumption .
Chklovsky and Sagan also knew each other very well, since in 1966 they co-authored a book translated into English called ”which may be regarded as the first serious exposition of the subject. This prompted them, in particular, to study more closely the possible technosignature of an advanced extraterrestrial civilization, “Type III” on that is, having at its disposal all the power emitted by the galaxy in which it is located.
Galaxies filled with Dyson spheres?
Let’s go back to what Futura has already written about the concept of a Dyson sphere. We owe this famoussadly deceased, who in 1960 sent a letter published in a newspaper . Influenced by a science fiction book called starmakerOlaf Stapledon, Freeman Dyson decided to check whether the ideas expressed in Stapledon’s work are credible in terms of without worrying about the complex technological problems that arise in their implementation.
Extrapolating the curve of growth in the consumption of energy and matter by mankind, we inevitably come to the conclusion that we will eventually need all the energy released by mankind.Every year. Dyson then calculated that with material equivalent to material , it is possible to surround our Sun with a semi-solid shell two to three meters thick, capable of delaying the radiation of our star. This is what a Type II civilization would do to its star on the famous Kardachev Scale.
However, according to the laws ofeven using most of the energy thus available, the shell will heat up and re-radiate in the infrared as excellent quality. in the star is close to a black body, but a fairly accurate observation quickly shows that it is actually split by a series of rays even, sometimes, groups. This would not be the case with the object Dyson is studying.
Therefore, the method he proposed for detecting extraterrestrial civilizations is to go in search of cold objects emitting in the infrared, like an almost perfect black body, and the size of which will be on the order of several.
The concept made a fortune under the name “Dyson sphere” and was notably popularized by Carl Sagan in his writings, for example Space.
Sagan and Chklovsky extended Dyson’s idea of a technosignature to the case of a Type III civilization, and it is this signature that JWST would begin to see at the level of at least one galaxy in infrared.
Caution is needed because, as we have explained, the telescope setup is not finished and it could be an artifact of one of the poorly calibrated instruments.
