The reason the first generation (Pop III) stars were massive is that a 75%/25 % hydrogen molecule/helium atom mix is pretty hard to cool down and get to collapse to a star forming disk. There is not enough atom and molecular bands for efficient IR emissions as in more complex elements mixed in...

Science site articles span press releases to interviews. So if a topic interests you, you have the right to complain but you can also often find an answer in other site's articles. In this case the paper itself is just a Q value progress report while the phys.org article contains interview parts...

That was a poignant last routine. I'm not sure I understand your rant, if it is meant to be understood. But we don't "prove" facts, we test them. And e.g. the arrival of Ingenuity to Mars tests that current astronomy is correct (if the opposite was what you wanted to claim). I'm not sure I...

There is a large latitude in models, and it will take more missions to Uranus and Neptune to sort it out. "Although the [composition] model considered above is reasonably standard, it is not unique; other models also satisfy observations." https://en.wikipedia.org/wiki/Uranus Then you don't...

Bon voyage, Voyager!

A shield volcano on the high side could make more sense of the erosion channel of Valles Marineris with lava and/or water flows. It sits with the Tharsis bulger region of a deep mantle diapir potentially feeding it to its size and longevity. Missing the /i sign? Mars is another planet. The LPSC...

Scientists consider pseudoscience harmful. https://en.wikipedia.org/wiki/Plasma_cosmology Science usefulness comes in that it is evolving, expanding descriptions, so claiming that it must be like a pseudoscience belief is like claiming that a hammer is failing because the building is under...

I had heard that Freedman is working with JWST, This article vets my appetite for the result! (Though if she is still using Cepheids the result won't likely tell on the distance ladder problems. Based on Planck data Efstathiou show that its problems lies above the pivot scale z > 0.005, which is...

To add to what KMcB said, I agree that JWST hasn't "broken" cosmology but that the ongoing work confirm that science and scientists work as they should. Even if today's supernova results were a fact the DES survey results showed that the universe would follow standard LCDM (being flat, i.e...

Frenk goes on:

What a difference two months do, the origibal Conversation article was written as the first Webb observations - as hoped for - would entice and confound the astronomical community. Since then the early question have had - as expected - mainstream explanations and Webb has joined the ever...

The paper was looking at possibilities: "could have evolved life more advanced than our own." Anatomically modern humans almost certainly is a rare outcome of evolution - if that and not intelligence is your yard stick - but the planet numbers stack up. The so called "paradox" was a question...

There are many scientists that wish that the Webb telescope (or other observations) turn over the consensus model for professional reasons (since academia advances are hard). I note that you rely on general popularizers instead of scientists to form your ideas about the science, and as a...

The early universe was a busy place:
