  • Webb observerer den glødende aske af kolliderende neutronstjerner

    Gammaglimt er kortvarige udbrud af den mest energirige form for lys, som når os fra det fjerne Univers. De har deres oprindelse i stjerneeksplosioner, men de præcise omstændigheder er stadig uklare. Nu har et hold forskere, inklusiv astronomer fra Niels Bohr Institutet, brugt rumteleskopet James Webb til at studere et gammaglimt, som viste sig at være det næst-klareste nogensinde. Studiet, som netop er blevet udgivet i Nature, afslører skabelsen af grundstoffet tellurium, hvilket ikke er set før.

  • Webb observes the glowing embers of colliding neutron stars

    Gamma-ray bursts are brief flashes of the most energetic form of light, reaching us from the distant Universe. They have their origin in stellar explosions, but the exact circumstances are still debated. Now a team of researchers including astronomers from the Niels Bohr Institute has used the James Webb Space Telescope to study a gamma-ray burst, which turned out to be the second-brightest ever seen. The study, which has just been published in Nature, revealed the creation of the element tellurium which had not been recognized before.

  • Neutronstjerner giver astronomer en ny måde at måle Universets udvidelse på

    De seneste år har astronomien stået i lidt af en krise: Selvom vi ved at Universet udvider sig, og selvom vi ved nogenlunde hvor hurtigt, stemmer de to vigtigste måder til at måle denne hastighed ikke overens. Nu foreslår astrofysikere fra Niels Bohr Institutet en ny målemetode, som potentielt kan løse krisen.

  • Colliding neutron stars provide a new way to measure the expansion of the Universe

    In recent years, astronomy has seen itself in a bit of crisis: Although we know that the Universe expands, and although we know approximately how fast, the two primary ways to measure this expansion do not agree. Now astrophysicists from the Niels Bohr Institute suggest a novel method which may help resolve this tension.
