James Web discovers the impossible light at the dawn of the universe

he James Web telescope for space Record A An unexpected light signal from Gades GS-Z13-1It is in the era of the universe where light, according to the current models, should not be able to escape.

During hundreds of millions of years after The Big BangThe universe was drowned in a Incredible fog of neutral hydrogen. At that time, known as the name It was darkand The light of the first stars or galaxies cannot travel freelyDue to the absorption of photons by the environment between galaxies.

However, the Webb discovered a strong broadcast of Leman Alpha – Oz created by enthusiastic hydrogen atoms – in a galaxy that was present only 330 million years after the origin of the universe.

“We have discovered an intense emission from Lyman-Aalfa in a galaxy to Redshift 13”The team, led by astronomical physics Uwres knows In the magazine nature.

A bubble of clarity in the midst of the oral universe

The reference is not only challenging your expectations intensityBut for him Physical participation: So this light escaped, The galaxy had to generate its specific space bubbleCleansing the fog that surrounded it. This condition can only occur if Very hot stars or a super black hole They emitted enough radiation to transform the environment.

“A portion of 5 and 10 % of the flow can be transferred through the environment between galaxies,” the details of the article, support the hypothesis a Local Bourboga Maida.

Stars of population or primitive black hole?

The research team looks at two potential sources of this bubble:

1. Third population starsThe virtual giant stars without minerals would have formed the first stellar generations of the universe.

2. Active galaxy nucleusPayed by a The superior black hole He would have started his activity after a few hundred years after the big explosion.

The study says: “The active galaxy nucleus is an applicable possibility to explain the monitored properties,” the study says.

A small galaxy with a large effect

Jades -gs-Z13-1 is very smallWith a radius, only the estimated diameter 35 PARSECs (About 114 light years), but her spectrum reveals High efficiency in the production of ionized photons And one Very blue UV inclination (βuv ≲2.7). These signs indicate a group of small and very active stars, with a few dust particles that prevent light.

In addition, models show that the efficiency of their photon production It exceeds the limit of traditional stars (ξion ≈ 10^26.5 Hzz Erg⁻⁻), which enhances the hypothesis of an unusual object.

Has the universe become transparent in a greatest time of thought?

This result Classical schedule question for cosmic re -eternityThe process that turned the universe without transparent into transparent. According to the traditional model, only The most huge galax They were responsible for this change. but Jades-gs-z13-1With a decrease in its lower shine and size, it suggests this Small galaxies also played a major role When creating “windows” of clarity in the cosmic fog.

The study concluded that “the existence of an area that was rejected on this source of relatively weak UV rays imposes restrictions on the time sequence of re -cosmic.”

The cosmic dawn still keeps secrets

This discovery opens a A new stage in observation cosmology. The next stage of the study seeks to confirm whether this bubble is resulting Primitive Or by An active black holeWhat can reveal How the first light sources appeared in the universe.

With every new note, James Web telescope Not only does the old galaxies, but also Restructuring our understanding of the origin of the universe. This time, he did so Light where darkness should be only.
