An international team led by the University of Geneva (UNIGE) has identified three ultra-massive galaxies—nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang.

Discovery of three galactic 'red monsters' in early universe challenges current models of galaxy formation

If another gravity theory is correct, "then the broader implications are enormous," astrophysicist Stacy McGaugh told Newsweek.

NASA Webb revelations challenge traditional theory of gravity

The formation of galaxies in the early universe will not respond to the most widespread theory among scientists, which contemplates the existence of dark matter, suggests a research team that used data from the James Webb Space Telescope and adopted another hypothesis.
The standard model predicted that Webb would see faint signs of small, primitive galaxies, but according to a study published in The Astrophysical Journal, the data doesn't confir…

A formação de galáxias no universo primitivo não responderá à teoria mais difundida entre cientistas, que contempla a existência de matéria negra, sugere uma equipa de investigação que utilizou dados do Telescópio Espacial James Webb e adotou outra hipótese.
O modelo padrão previu que Webb veria sinais fracos de galáxias pequenas e primitivas, mas de acordo com um estudo publicado no The Astrophysical Journal, os dados não confirmam que a matéri…

Study casts doubt on the theory of galaxy formation

Astronomers have identified three ultra-massive galaxies -- nearly as massive as the Milky Way -- already in place within the first billion years after the Big Bang. This surprising discovery was made possible by the James Webb Space Telescope's FRESCO program, which uses the NIRCam/grism spectrograph to measure accurate distances and stellar masses of galaxies. The results indicate that the formation of stars in the early Universe was far more …

Three galactic 'red monsters' in the early Universe

Once again, the James Webb Space Telescope has discovered galaxies that are forming stars so effectively so early that it does not fit the standard model of cosmology.

Wieder hat das Weltraumteleskop James Webb Galaxien entdeckt, die so früh so effektiv Sterne bilden, dass es nicht zum Standardmodell der Kosmologie passt.

James Webb Space Telescope: "Red Monster Galaxies" Problem for the Standard Model

Three galactic “red monsters” have been discovered in the early Universe by an international team led by UNIGE. Their measurement indicates that the genesis of stars in the early Universe was much more efficient than scientists thought. Existing models of galaxy formation probably need to be reviewed.

Trois "monstres rouges" galactiques ont été découverts dans l'Univers primitif par une équipe internationale dirigée par l'UNIGE. Leur mesure indique que la genèse des étoiles dans l'Univers primitif était beaucoup plus efficace que ne le pensaient les scientifiques. Les modèles existants de formation des galaxies sont probablement à revoir.

Three ultra-massive galaxies spotted surprisingly soon after the Big Bang

Modern astronomers have speculated that, in the beginning, all galaxies formed in large halos of dark matter, a mysterious-yet-abundant substance that doesn't shine or interact with light.These halos would have captured gas into gravitationally bound structures, turning about 20 percent of that gas into galaxy-residing stars. But new research from the James Webb Space Telescope, a collaboration of NASA and its European and Canadian counterparts,…

Webb telescope scientists forced to reckon with enormous galaxy outliers

Observations of the early universe made by NASA's flagship James Webb Space Telescope are challenging the traditional theory of gravity and how the first galaxies formed.
This is the conclusion of a new study by astrophysicist Stacy McGaugh—of Ohio's Case Western Reserve University—and his…

NASA Webb Revelations Challenge Traditional Theory of Gravity

Astronomers have spotted massive red galaxies dating back to the first billion years of the universe’s life. Some are almost as large as the Milky Way. Three Red Monsters. Credits: NASA/CSA/ESA, M.
