Main information – Astronomers have discovered unchanged galaxy
- This galaxy remained practically unchanged for 7 billion years.
- Kids J0842+0059 bypassed the second phase of formation of galaxies which involves significant mergers. Furthermore, changes in size and stellar populations.
- Scientists believe that future observations will discover other galaxies.
A team of astronomers has made a revolutionary discovery by observing a galaxy which has not changed for 7 billion years. For example, Kids J0842+0059. In addition, as it is called, offers a unique overview of the distant past and provides new information on the evolution of galaxies.
The galaxy is located about 3 billion light years from the earth. Meanwhile, It is distinguished by its exceptional stability. While most galaxies merge and evolve in a dynamic way over time, this object has remained practically intact. With its compact astronomers have discovered unchanged galaxy size and immense stellar density, it differs greatly from typical galaxies such as the Milky Way.
The discovery – Astronomers have discovered unchanged galaxy
This discovery sheds light on the process of training galaxies, which takes place in two stages. The first step is a rapid explosion in stars formation, which leads to a dense and compact nucleus. In a second step, the interactions between neighboring galaxies lead to mergers and significant changes in size and stellar population. Kids J0842+0059 seems to have jumped this second phase. Since its initial star training, it has retained about 75 percent of its mass. The reasons for this exceptional immobility remain obscure.
Astronomers suspect the black supermassive holes to play a role. This is what they reported to CNN. They would heat or expel gas, thus stopping the formation of new stars. However, additional research is necessary to confirm this hypothesis.
Observations et confirmation
Confirmation of Kids J0842+0059 as astronomers have discovered unchanged galaxy a fossil galaxy required detailed observations with the large binoculalar telescope. in Arizona. This telescope is renowned for its sharpness, even in the presence of atmospheric disturbances. The accuracy of the telescope allowed astronomers to determine the age, size and mass of the galaxy with remarkable precision.
Kids J0842+0059 joins a small group of fossil galaxies already discovered. One of the best known examples is NGC 1277, which has already been studied with the Hubble space telescope. Although the two galaxies have many common points, Kids J0842+0059 is located at a greater distance from the earth.
The future and meaning
The future of Kids J0842+0059 remains uncertain. Its current state probably persists due to an unknown mechanism which prevents interactions with other galaxies. Scientists think that the galaxy will remain unchanged. However, the lack of understanding of his isolation makes predictions difficult.
The identification and confirmation of fossil galaxies are astronomers have discovered unchanged galaxy a major challenge. They are rare and much smaller than typical galaxies. However, current efforts with advanced telescopes like Euclid should make it possible to discover more of these enigmatic galaxies. Researchers thus hope to better understand the training and evolution of galaxies.
