Teleskop Džejms Veb otkriva spajanje pet galaksija samo 800 miliona godina nakon Velikog praska
Astronomi sa Teksaskog univerziteta A&M otkrili su retku, zbijenu koliziju galaksija u ranom univerzumu, što sugeriše da su galaksije bile u interakciji i oblikovale svoje okruženje mnogo pre nego što su naučnici smatrali.
TL;DR
- Astronomers discovered a dense collision of at least five galaxies in the early universe, about 800 million years after the Big Bang.
- The "JWST quintet" shows galaxies interacting in a compact region with evidence of heavy elements dispersed outside the galaxies.
- This finding contradicts previous expectations that such complex mergers and widespread element enrichment would only become common much later in cosmic history.
- The discovery suggests that theories on galaxy assembly and the speed of these processes need to be updated.
- This early, rapid merging could help explain the existence of massive, quiescent galaxies observed in later epochs.
