Astronomers Say They Have Spotted the Universe’s First Stars




"A group of astronomers poring over data from the James Webb Space Telescope (JWST) has glimpsed light from a rare isotope of helium in a distant galaxy, which could indicate the presence of the universe’s very first generation of stars."

"These long-sought, inaptly named “Population III” stars would have been ginormous balls of hydrogen and helium sculpted from the universe’s primordial gas. Theorists started imagining these first fireballs in the 1970s, hypothesizing that, after short lifetimes, they exploded as supernovas, forging heavier elements and spewing them into the cosmos. That star stuff later gave rise to Population II stars more abundant in heavy elements, then even richer Population I stars like our sun, as well as planets, asteroids, comets and eventually life itself.

(The one creating the stars didn't create life the star did?

Come on now, these people crack me up...)


'Even if the researchers are wrong, a more convincing detection of the first stars may not be far off. JWST, which is transforming vast swaths of astronomy, is thought capable of peering far enough away in space and time to see them. Already, the gigantic floating telescope has detected distant galaxies whose unusual brightness suggests they may contain Population III stars."


"A definitive discovery

(This isn't at least not yet)

 would allow astronomers to start probing the stars’ size and appearance, when they existed, and how, in the primordial darkness, they suddenly lit up.

“It’s really one of the most fundamental changes in the history of the universe,” Bowler said."



Lets review.

Day one = Universe inflation = Light.




Genesis 1:3

Then God commanded, “Let there be light”—and light appeared.





1st stars, 400 million years in development.

Day four = Let the lights appear in the sky =  = Star formation.

Genesis 1:14

Then God commanded, “Let lights appear in the sky to separate day from night and to show the time when days, years, and religious festivals begin;


This is why the creation of light is mentioned twice in Genesis.

Where's the more complete creation story?

Good luck.


"Population III

About 400,000 years after the Big Bang, electrons, protons and neutrons settled down enough to combine into hydrogen and helium atoms. As the temperature kept dropping, dark matter gradually clumped up, pulling the atoms with it. Inside the clumps, hydrogen and helium were squashed by gravity, condensing into enormous balls of gas until, once the balls were dense enough, nuclear fusion suddenly ignited in their centers. The first stars were born."

"The German astronomer Walter Baade categorized the stars in our galaxy into types I and II in 1944. The former includes our sun and other metal-rich stars; the latter contains older stars made of lighter elements. The idea of Population III stars entered the literature decades later. In a 1984 paper that raised their profile, the British astrophysicist Bernard Carr described the vital role this original breed of star may have played in the early universe. “Their heat or explosions could have reionized the universe,” Carr and his colleagues wrote, “… and their heavy-element yield could have produced a burst of pregalactic enrichment,” giving rise to later stars richer in heavier elements."
