Summary

Story summary

Y1 is a galaxy forming stars 180 times faster than the Milky Way, challenging cosmic-evolution theories.
It lies over 13 billion light-years away, with dust at about 90 Kelvin driving the high star-formation rate.
Researchers led by Tom Bakx from Chalmers University will use advanced telescopes to study more galaxies like Y1.
The results imply early galaxies formed stars and dust more readily than thought, reshaping views of early-universe evolution.
