With the passage of time and the advancement of technology, new discoveries have come when we talk about space, and this has been reflected in important discoveries in the form of new stars, even materials that were previously unknown due to outer limitations. There was atmosphere of exploration. And now, a new milestone has been reported that’s worth mentioning, because let’s remember that there’s so much to discover out there, and we’re not just referring to our solar system.
Astronomers have discovered the oldest known galaxy ever observed JADES-GS-z14-0, which provide valuable information for current galactic formation models. It shows what the universe looked like 290 million years later the big bangIt provides an opportunity to study the Cosmic Dawn, the period 100 to 1,000 million years after that event, when the first galaxies formed and the structures of the universe began to take shape.
The discovery was made in January 2024 using the space telescope’s Near-Infrared Spectrograph (NIRSpec). James Webb. This instrument, which breaks light into spectra to analyze the physical properties of objects, allows astronomers to observe JADES-GS-z14-0 for about 10 hours, confirming that this galaxy is even older than UHZ1, the previous most distant galaxy that formed 470 million years after the Big Bang.
The galaxy is more than 1,600 light-years in diameter, indicating that its light comes from young stars rather than nearby emissions, such as from an accreting supermassive black hole. The discovery is important for understanding how the universe formed after the Big Bang 13.8 billion years ago, according to researcher Stefano Carniani of the Scuola Normale Superiore in Italy and Kevin Heinlein of the University of Arizona.
Through: the nature
Author’s Note: It is always positive that new discoveries are made, and it is important to know if there will one day be a new habitable galaxy. It will take time to become a reality, but it will be interesting for the new generation to achieve it.
