How real are the images from NASA’s James Webb Space Telescope

(ORDO NEWS) — Looking at the popular images transmitted by NASA’s James Webb Space Telescope , one involuntarily thinks about how perfect, amazing and attractive the Universe is, which at any point is a perfect work of art.

Of course, the universe is incredibly beautiful, but not as beautiful as the James Webb shows us … or any other predecessor space telescope that transmitted thousands of images.

NASA is fooling us?

No, NASA is doing a great service by giving non-specialists the opportunity to touch the mystery of the universe. And now you will understand everything.

So, the images from the James Webb Space Telescope are not what your eyes would see if you were close to this or that observed object, since these images are a visualization of the data.

And this data is the result of the impact of photons, light energy, on the extremely sensitive instruments of a space telescope located at a distance of 1.6 million kilometers from us.

The instruments, the James Webb sensors, measure the energy and transmit the data to Earth, where teams of scientists convert it into something that the human eye can see.

For uninformed people, such an unusual rendering may arouse suspicion, because some kind of “strange manipulations” are carried out with the images, and as a result something “artificial” is shown.

Sure, any dataset can be manipulated, but astronomers have clear standards and methods to ensure that their visualizations convey not only useful but also realistic information about the world.

In other words, the visualization of the data transmitted by “James Webb” is as accurate as the solution of a typical mathematical problem using specific formulas.

NASA is interested in making the Universe exciting, as it is a reliable way to make science exciting, inviting and encourage people (especially the younger generation) to be interested in it, and at best, to do it.

Scientists, on the other hand, can do without visualization, since all the data that is most interesting to them is presented in spreadsheets or on spectrograms, diagrams that show the presence of certain elements based on the frequency of light reflected, absorbed or emitted by a space object.

Conclusion: Images from NASA’s James Webb Space Telescope are a great opportunity provided by science to see what is inaccessible to the human eye.
