Webb discovers Lyman-Alpha emissions from ancient galaxy in early universe

The universe continues to reveal its secrets as science advances in its exploration. An international team of astronomers has managed to detect signs of oxygen and heavy metals in the most distant galaxy of the Milky Way known so far, located 13.4 billion light years from Earth.This finding, made thanks to the capabilities of the James Webb space telescope and ALMA observatory, challenges what was known about the formation of galaxies in the pri…

Webb discovers Lyman-Alpha emissions from ancient galaxy in early universe

The light of Lyman Afa from Jades-GS-Z13-1 took us nearly 13.47 billion to contact us, as it dates back just 330 million years from the Big Bang. This image shows the Jades-GS-Z13-1 (middle red dot) imaged with Webb’s near-infrared camera (Nircam) as part of the Jades program.

Astronomers have identified the presence of oxygen in the most distant galaxy ever observed, JADES-GS-z14-0, whose light took 13.4 billion years to reach Earth. This discovery challenges theories about the early formation of galaxies and suggests that they evolved much faster than expected. How is the presence of oxygen detected on other planets and what does it mean? The finding, made with the ALMA telescope, indicates that the galaxy is surpri…

Kornmesser , CC BYThe top image represents JADES-GS-z14-0, the newly discovered galaxy in the southern constellation of the Oven. It could be one more galaxy among the billions that populate the universe, but it holds a record of enormous scientific interest: it is the furthest away from planet …

The discovery of oxygen, an element that was not present in the primitive universe and can only emerge from the interior of evolved stars, suggests that JADES-GS-z14-0 was formed and enriched chemically much faster than the current models predicted.
