James Webb finds surprisingly mature galaxies in early cosmic megastructure
Using the powerful James Webb Space Telescope, an international team of researchers led by a Danish astronomy student at the Cosmic Dawn Center in Copenhagen showed that some of the most massive galaxies in the early Universe were evolving more rapidly than expected. Studying a recently-discovered enormous galaxy cluster, the “Cosmic Vine”, the astronomers found that the huge structure hosts many additional galaxies, including several massive “dead” galaxies that have already stopped forming stars.

James Webb finder overraskende modne galakser i tidlig kosmisk megastruktur
Ved hjælp af rumteleskopet James Webb har et internationalt forskerhold, ledet af en dansk astronomistuderende ved Cosmic Dawn Center i København, vist at nogle af de tungeste galakser i det tidlige Univers udviklede sig hurtigere end forventet. Ved at studere en gigantisk, nyligt opdaget galaksehob, “Cosmic Vine”, fandt astronomerne, at den enorme struktur rummer mange flere galakser, herunder flere tunge “døde” galakser, som allerede er stoppet med at danne stjerner.

Galaktisk støv afslører skjulte mønstre i nye imponerende billeder fra James Webb
Ved hjælp af rumteleskopet James Webb har et forskerhold, ledet af en dansk bachelorstuderende, afdækket overraskende nye detaljer om finstrukturen af kosmisk støv i nære galakser. Dette støv — bittesmå partikler, der svæver rundt i rummet — spiller en nøglerolle i, hvordan stjerner og planeter dannes, og hvordan galakser udvikler sig. Det nye studie viser, at forskellige slags støvskyer opfører sig på meget forskellige måder, og kan endda hjælpe med at præcisere størrelsen af de mindste mønstre, som støvskyer danner naturligt i galakserne.

Galactic dust reveals hidden patterns in stunning new images from James Webb
Using the James Webb Space Telescope, a team of researchers led by a Danish bachelor student has uncovered surprising new details about the fine structure of cosmic dust in nearby galaxies. This dust — tiny particles floating in space — plays a key role in how stars and planets are born, and how galaxies evolve. The new study shows that different kinds of dust clouds behave in very different ways, and even helps pinpoint the size of the smallest patterns that dust clouds naturally form inside galaxies.

Astro-Pic Of the Day
- Hubble: Decagon Around Saturn's South PoleWhy are Saturn’s poles geometric? Saturn’s North Pole has been known to be surrounded by a hexagonal (6 sides) cloud since discovery in 1987 in data taken by NASA’s Voyager spacecrafts, which quickly flew past the ringed world in the early 1980s
