- Euclid ESA has revealed images of two of the most distant galaxies selected from 31 objects, with a telescope time of 670 million years.
- The discovery of the most distant galaxies is expected to take time, which the Euclid telescope will spend observing, with a total of 670 million years. This is about 5% of the total time of 13.8 billion years.
- The materials named the galaxies EUCL J172902.75+641018.1 and EUCL J125308.55+705432.3; the names are given for internal use for identifying the sources from the images.
According to the ESA, the Euclid space telescope has revealed images of two of the most distant galaxies, which appear to be in the early universe. The images show galaxies that are expected to be among the earliest observed, with a telescope time of 670 million years.
The materials state that the 5% of the total time in which the observations were made corresponds to 13.8 billion years. In addition, the paper explains that the galaxies, which are identified as EUCL J172902.75+641018.1 and EUCL J125308.55+705432.3, are likely among the earliest galaxies ever observed, dating back to 2021. The paper also notes that the galaxies are located at a distance of 20 million years.
The materials also state that the two newly discovered galaxies may have names EUCL J172902.75+641018.1 and EUCL J125308.55+705432.3. An ESA publication notes that the images with the names are part of the early universe research, which is being carried out with the help of the telescope.
The materials add that the research suggests that the galaxies are likely to have formed through gravitational collapse. The paper also states that Euclid, which was launched in 2024, is designed to map the universe, and the telescope’s observations are expected to cover a sky area of 1.5 million square kilometers on Earth.
The materials are also said to be related to Daming Yang, the lead author of the study, published on June 6, 2026. He says: “The galaxies are so distant that Euclid’s observations are expected to reveal their formation and evolution. Euclid’s data may help researchers understand how galaxies formed in the early universe.”
It is also noted that the new galaxies may be located in a region of space where the first galaxies formed, which is why the researchers believe that the galaxies are among the earliest ever observed. The materials also note that Daming Yang believes that the galaxies are “a rare example” of how galaxies might have formed in the early universe.
The materials also state that the James Webb space telescope will observe the galaxies, and Joseph Hennawi says, based on the results, that the observations will help researchers understand the “chronicle of galaxy formation” over the past million years.
