Last April, scientists with the University of Texas published findings in Nature Astronomy that showed several galaxies that existed during the early universe, but appeared to have far greater mass than they should.
Astronomers using the James Webb Space Telescope (JWST) have discovered a massive galaxy that's so old its existence should be impossible, posing a challenge to current theoretical models on dark matter. As detailed in a new study published in the journal Nature, the so-called quiescent galaxy, ZF-UDS-7329, contains more stars than the Milky Way — […]
Distant galaxies that existed a few hundred million years after the Big Bang are brighter than expected in JWST images because they were experiencing bursts of intense star formation.
Using the James Webb Space Telescope, astronomers discovered that, between 7 and 10 billion years ago, there were fewer feeding supermassive black holes than previously thought
