Here is where the initial galaxies are created.

Around 13.8 billion years ago, the Big Bang occurred. It was 400 to 600 million years later when the first stellar systems arose. Scientists have recently been able to observe the genesis of these ancient galaxies.

Scientists uncover astonishing finding. - Here is where the initial galaxies are created.

"Astrophysicist Kasper Elm Heintz (33) from Denmark's Niels Bohr Institute declares, 'We're witnessing the birth of the first stellar systems in the universe,' as his team uncovers images of galaxy formation with the help of the powerful infrared lens of the James Webb Space Telescope."

This fascinating revelation: "The JWST has previously captured pictures of forming galaxies in later stages, but here we're witnessing their conception and genesis."

Peering at the cosmic dawn

Heintz and his international crew employed the JWST's infrared sight to gaze towards the cosmic dawn, uncovering a signal that emanates from three galaxies. This signal originates from neutral hydrogen, a gas enveloping the celestial bodies, as it soaks up and radiates the galaxies' light.

"These galaxies resemble shimmering isles in a vast sea of otherwise opaque, neutral gas," explains Heintz. Cosmologist and astrophysicist Darach Watson of the Niels Bohr Institute also describes, "During the first few hundred million years after the Big Bang, the first stars swarmed into being, merging with both gas and space, thus fertilizing the grounds of abysses we now call galaxies. This is the onset we've captured in our observations."

How did we get here?

With this discovery, experts can delve deeper into these early galaxies, uncovering more knowledge about the universe's formation process, shedding light on humanity's most profound question: Where do we come from?

"We're putting together pieces of the answer by observing the formation of some of the first structures in the universe," says astronomer Gabriel Brammer. "We're continuing our research in the hope of answering more parts of this epic puzzle."

According to researchers, the galaxies are like sparkling islands in a sea of gas
