Galaxy secret ventilated: astonishing discovery after the big bang!
An international research team in which the University of Geneva is also involved has made a groundbreaking discovery of the development of the universe. According to a report by oe24 was identified that only 700 million years after the upper Bang stopped to form new stars. This discovery takes place much earlier than previous models for the development of the universe.
In the period of 700 million years, which corresponds to a twentieth of the total time since the big bang, these findings show that galaxies attract gas from their surroundings in order to form new stars, which favors their growth. Surprisingly, the process of "quenching", which stops star formation, is not yet fully understood by the researchers.
new knowledge of dead galaxies
The researchers discovered the distant and oldest massive dead galaxy with the James Webb WeltPraumelescope, which formed around ten billion stars in the first 600 million years after the Big Bang before the star formation set up 700 million years after the big bang. This newly obtained data suggests that such massive, dead galaxies have occurred over 100 times more often than previously assumed in the first billion years of the universe. The results were published in the journal "The Astrophysical Journal" and could lead to models for galaxy development.
The discovery raises important questions: How exactly did this sudden standstill of star formation occur? What makes these galaxies so different? The exact mechanism that drives this process remains a mystery that the astronomers continued.
A look at isolated dwarf galaxies
Another remarkable discovery was made around the isolated dwarf galaxy Leo P, which contains a few hundred thousand stars and is 5.3 million light years away from the Milky Way. Studies show that Leo P is not directly influenced by the Milky Way or Andromeda Galaxy. According to a report on World of Physics was analysis of around 15,000 stars in Leo P using the James-Webb-Telekops.
The history of the star development in Leo P was in three phases: The first phase lasted up to 12.6 billion years ago and includes the era of reilonization. This was followed by a second phase in which there was no star development for 2.5 billion years until the third phase began to date. Interestingly, the third phase in non -isolated dwarf galaxies in the area, which indicates possible specific circumstances in Leo P.
Possible explanations for the new star development in Leo P include the proximity to other galaxies or gas with low density that could have triggered reactions. A possible merger with another galaxy could also have caused gravitational changes that stimulated star formation.
These findings illustrate how much to learn about the processes in the early galaxies and the variety of star tension stories in the universe. The progress in astronomy, especially through modern telescopes such as the James Webb telescope, enable scientists to better examine isolated galaxies such as Leo P and their history.
