It is a new record that takes us far in space and time. Researchers from Harvard (USA) announced on April 7, 2022 in the journal Astrophysical Journal the discovery of the most distant galaxy ever observed. “HD1” is 13.5 billion light years away from us. That’s 100 million more than “GNz11”, the defending champion. And … Read more
The glimpses of ‘Earendel’ and ‘HD1’ mark two milestone advances in astronomy, allowing us to better discern the earliest remnants of the universe, dating back billions of years. Astronomy is a formidable time machine: the more modern the tools, the more advanced the technologies, and the better we manage to uncover the first remnants of … Read more
Dwarf galaxies are affected by the same evolutionary processes that operate in large galaxies such as the Milky Way or the Andromeda Galaxy. They are less luminous and less massive than their older sisters, and they are particularly sensitive to the environmental mechanisms caused by the presence of a giant galaxy in their vicinity. In … Read more
Since ancient Greece, people have wondered about the material composition of the material… of the material. The philosopher Democritus had proposed that everything that exists actually consisted of infinitely small and indivisible bodies: atoms. It is clear that Democritus could not scientifically prove the existence of the atom; it was just a guess. His reasoning … Read more

Observing the distant stars born shortly after the Big Bang is a real challenge. However, astronomers have succeeded by using an innovative method: they use certain galaxies that deform light and play the role of a natural telescope. As telescopes become more sophisticated every day, they reveal ever more distant and detailed objects to us. … Read more
Half of the stars similar to our sun are what astronomers call double stars. In reality, systems are formed by two stars orbiting each other. A configuration that is not without significance for the composition of the planets that surround them. Including planets that could host extraterrestrial life. There are so manystarsstars in our UniverseUniverse. … Read more
Half a century after Rubin’s work, astronomers have still not been able to directly observe dark matter. It neither emits nor reflects light. It does not interact directly with ordinary matter, although its gravity affects the behavior of observable objects such as stars and galaxies. Scientists also believe that dark matter is necessary for galaxies … Read more
Since Thursday, May 12, 2022, and the publication of the 1st image of the supermassive black hole at the center of our galaxy, much has been communicated about this strange and mysterious object, whose existence we suspected for a long time time, but which we had never “seen” before. But what is its influence on … Read more
It dates from the beginning of the universe, more precisely about 500 million years after the Big Bang. It is the oldest rotating galaxy ever observed and provides clues to the formation of primordial galaxies. Scientists have just discovered galaxygalaxy furthest rotation ever observed. It crossed over 13.26 billion light years before reaching us and … Read more
