  • 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.

  • Den kraftigste eksplosion nogensinde set

    Gammaglimt er de kraftigste eksplosioner i Universet, og markerer afslutningen på en stjernes liv. Et særlig kraftigt glimt blev for nylig observeret af flere rumteleskoper. Et team af forskere, ledet af astronomer ved Cosmic Dawn Center, målte den nøjagtige afstand til eksplosionen, hvilket gjorde det muligt for dem at beregne den totale udløste energi: I løbet af de blot fem minutter, glimtet varede, udløste det mere energi, end vores Sol har udsendt gennem hele sit 4½ milliarder år lange liv. Dette gør glimtet til det mest energirige, der nogensinde er opdaget.
