The journey of James Webb Space Telescope is a story of perseverance, innovation and international collaboration that promises to revolutionize our understanding of the universe.
His idea began to be developed in the 90s and, today, it is the largest telescope that has ever been launched into space. Thanks to its technology, which uses infrared wavelengths, we have had fascinating records.

However, the fascinating can also turn out to be a frightening fact! It turns out that the NASA has identified a nebula that could raise tragic questions about the future of the Sun.
Certainly, the future of our Sun is a valid concern when it comes to the long-term habitability of Earth and life as we know it.
Although our Sun is essential to sustaining life on our planet, it is not eternal and will undergo significant changes throughout its evolution.
A possible tragic trajectory for our Sun is linked to its life cycle and the changes it will eventually undergo.
The image recently revealed by NASA, captured by the space telescope, shows the impressive Ring Nebula, also known as “Messier 57”.

It is a planetary nebula located in the constellation of Lyra, approximately 2,300 light-years away from Earth. The term “planetary nebula” can be a little misleading, as it has nothing to do with planets.
Instead, it is an evolutionary stage in the life of a star similar to our Sun. As a star ages and uses up the hydrogen in its core, it begins to shed its outer layers in a bright, colorful sphere of gas.
Its characteristics are similar to those of our Sun, so scientists believe that our star will suffer the same fate as the nebula.
University College London professor Mike Barlow used the Nas website to explain that, in addition to the rings, some arcs formed when the star was still a red giant.
Subsequently, most of its material was expelled, giving rise to a hot white dwarf.
