  • Astronomers discover newborn galaxies with the James Webb Space Telescope

    With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the Universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed. But for the first time we now see signs that this relation between the amount of stars and elements does not hold for the earliest galaxies. The reason is likely that these galaxies simply are in the process of being created, and have not yet had the time to create the heavy elements.

  • Danske astronomer opdager nyfødte galakser med rumteleskopet James Webb

    Med opsendelsen af rumteleskopet James Webb er astronomer nu i stand til at kigge så langt tilbage i tiden, at vi nærmer os den epoke, hvor vi tror de første galakser blev dannet. Gennem det meste af Universets historie ser de fleste galakser ud til at følge en tæt relation mellem hvor mange stjerner de har dannet, og hvor mange tungere grundstoffer de har dannet. Men for første gang ser vi nu tegn på, at denne relation mellem mængden af stjerner og grundstoffer ikke holder for de tidligste galakser. Årsagen er sandsynligvis, at disse galakser simpelthen er i gang med at blive skabt, og endnu ikke har nået danne de tunge grundstoffer.

  • Tidlig galaksedannelse fanget på fersk gerning med James Webb

    Astronomer fra Cosmic Dawn Center har afsløret karakteren af det tætteste område af galakser, som rumteleskopet James Webb har set i det tidlige Univers. De finder, at det sandsynligvis er oprindelsen til en tung, Mælkevejslignende galakse, set på et tidspunkt hvor den stadig er i gang med at samle sig fra mindre galakser.

  • Early galaxy formation caught in the act with James Webb

    Astronomers from the Cosmic Dawn Center have unveiled the nature of the densest region of galaxies seen with the James Webb Space telescope in the early Universe. They find it to be likely the progenitor of massive, Milky Way-like galaxy, seen at a time where it is still assembling from smaller galaxies.
