Nearby galaxies help astronomers understand distant galaxies
To better understand observations of the most distant galaxies, an international team of astronomers has built a sample of local galaxies which can be studied in much higher detail. In a newly published study they show how the amount of light that escapes from a galaxy is connected to its physical properties. The result has implications for how we interpret observations of galaxies in the early Universe.

Galakser i vores nabolag hjælper astronomer med at forstå de fjerneste galakser
For bedre at forstå observationer af de fjerneste galakser har et internationalt hold af astronomer opbygget et udvalg af lokale galakser, som kan studeres i langt højere detaljegrad. I et nyt studie viser de, hvordan mængden af ultraviolet lys, som slipper ud af en galakse, er forbundet til dens fysiske egenskaber. Resultatet har betydning for, hvordan vi fortolker observationer af galakser i det tidlige Univers.

The brightest explosion ever seen
Gamma-ray bursts are the most energetic explosions in the Universe, marking the end of a star’s life. A particularly bright burst was recently detected by several space telescopes. A team of scientists led by astronomers at the Cosmic Dawn Center measured the exact distance to the burst, allowing them to calculate the total energy released: During its duration of just five minutes it released much more energy than our Sun has emitted throughout its lifetime of 4½ billion years, making the burst the single most energetic ever detected.
