Something that will allow answering some questions … Read more
All stars are different. Each of them has its own character. His own “personality.” However, THE MECHANISM OF NATURE that has triggered the birth of most of those we can observe is always the same, so, in some way, we can consider that All are related. The stars are born from clouds of dust and … Read more

It was the year 1950. In Los Alamos, New Mexico, the best cafeteria conversation of all time took place. The physicist Enrico Fermi, eating with his colleagues Emil Konopinski, Edward Teller and Herbert York, asked: “Where is everyone?” The Fermi paradox was born. What does Fermi’s paradox say If our galaxy, the Milky Way, contains … Read more
Year 2019. In an underground laboratory, A kilometer and a half under the Masso del Gran Sasso in Italya dark matter detector witnessed something extraordinary: the radioactive disintegration of an atom of Xenon-124. It is the slowest process (And therefore, more rare) Never registered. They touched the cosmic lottery. The Xenon-124 has a semi-width of … Read more
Where is the dark matter is one of the great mysteries of the cosmos, but if someone thought we had all the barionic matter (the “conventional” matter) in the cosmos … it was wrong.

Astronomers They were convinced that the primitive universe was a dark place. That the galaxies took to appear after the Big Bang. But the new largest and most deep map of the universe, which extends until 13.5 billion years ago thanks to the observations of the James Webb space telescope, has just dynamited this idea. … Read more
The universe is full of spherical objects: stars, planets, black holes and a part of the satellites that we can find in our environment have more or less round shapes. However, there are other types of spheres (or rather other types), spheres that are not formed of compact matter but whose circular nature can be … Read more
From the first moments after the Big Bang, gravity has shaped the matter, giving rise to the intricate structures that define our universe. Galaxies, galaxy clusters and galactic filaments have evolved in ways that They almost always agree with Einstein’s general relativity theory. But something does not fit. The universe is more messy. A Recent … Read more
The immense capacity of the James Webb space telescope (JWST) to see the confines of the observable universe also allows us to see how our universe was billions of years ago. Recall that, the finitude of the speed of light implies that what we see further in space is also further in time, which makes … Read more
