The first stars in the universe are exceptional. A new podcast "Reviewing the formation of the universe's first stars", recently published on Scipod at https://www.scipod.global/prof-dr-ralf-klessen-reviewing-the-formation-of-the-universes-first-stars gives a concise overview of the astrophysics of their formation and their influence on the evolution of the universe. This podcast is based on a review article https://www.annualreviews.org/content/journals/10.1146/annurev-astro-071221-053453 by Heidelberg scientists Ralf Klessen and Simon Glover @zah_unihd. #firststars #astrophysics #universe #Heidelberg
Dark stars, which are thought to be the first stars in the universe, are predicted to have been made up of almost entirely hydrogen and helium, with less than 0.1% of their mass being dark matter.

Why we might finally be about to see the #FirstStars in the #universe
The first generation of stars changed the course of #CosmicHistory. Now, thanks to the #JamesWebbSpaceTelescope, we have a real chance of spotting them

#Astrophysicists discover a novel method for hunting the #firststars
The #NenuFAR #CosmicDawn project has taken an important step in the exploration of the Cosmic Dawn, this key period in our #universe marked by the formation of the #firststars. An upper limit on the amplitude of the #neutralhydrogen fluctuations at 21 cm has been established.
The #firststars of the #universe, made only of #hydrogen and #helium, about 300 times more massive than the #sun, formed the #heavierelements. A new #study suggests these ancient progenitors created more than just the natural elements.
Has JWST Finally Found the First Stars in the Universe?
In astronomy, elements other than hydrogen and helium are called metals. While that might make your high-school chemistry teacher cringe, it makes sense for astronomers. The two lightest elements were the first to appear in the universe. They are the atomic remnants of the big bang and make up more than 99% of atoms in the universe.

Stellar “Ashes” – Astronomers Discover Traces of Universe’s First Stars
Using ESO’s Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. They detected three distant gas clouds whose chemical composition matches what we expect from the first stellar explosions. These findings bring us one step closer to understanding the nature of the first stars that formed after the Big Bang.

The sober truth about finding the #Universe's #firststars - The Universe certainly formed stars, at one point, for the very first time. But we haven't found them yet. Here's what everyone should know.
