On July 29, 2022, website It is reported that the Noosphere discovered 5121 Since 51 Pegasi B, the discovery was made later thanks to the Nobel Prizes Michel Mayor and Didier Queloz. Futura recently gave an interview to Now world famous, French Jean Schneider.
Knowing the existence of these exoplanets is an extraordinary advance in the history ofsane man But it’s still very partial because, most of the time, we only have estimatesand distances for these exoplanets, a few of which are rare give Consists of for his fault.
Obviously, we would at least like to have pictures of the details of these exoplanets, especially if they areAbility. Ideally, we would even like to discover biometrics and even technical signatures there.
TheI recently allocated new funds to study an amazing project that can be implemented in the 21st centurye century for this. The project itself is only in the cards and there is no doubt that it has actually been implemented yet. Related For a concept proposed by a Stanford University researcher, VR Eshleman in 1979: Solar gravity.
Concretely, this means taking advantage of the fact that the field ofFrom a celestial body it deflects rays of light like a lens, thus providing a magnification factor for image formation. By standing at a distance from so it can be used as a file To form the image of an exoplanet with a stretch Record, as if we had a file Much larger than those that can be built on the ground due to who distorts a under its weight.
A swarm of telescopes powered by solar sails
Currently, the general thoughts on this topic are as follows:
By using a gravitational lens directly, as with a telescope, to make images of an exoplanet, we will get somewhat nebulous results. The best is to have multiple instruments flying in a swarm and each observing a portion of the equivalent of a ring ofFor the solar lens, that is, distorting the image of an exoplanet forming a ring, as in the case of some observations Using a strong gravitational lens produced by a .
Concretely, this would require sending this swarm to distances between 548 and 900 times the distance from Earth to the Sun, making it possible to form images of exoplanets up to about 100 light-years from the Sun. So, in theory, there is no problem in observing the exoplanets around it And the for example.
Using a single instrument with a mirror diameter of about one meter, we can obtain images of the surface of these exoplanets with a resolution of a few tens of kilometers.
However, there are many difficulties with this idea. With current propulsion technology, it would take about a century to send devices a good distance. We can at best shorten the period to about 25-30 years, which is reasonable for . The technique of these sails has not yet been mastered, although reasonably close.The life of a person involved in this project, using
