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.

First light from student-built radio telescope
During the last six months, academic employee Gaurav Kumar, together with master students Kaj Grimstrup, Liazhe Li, and Omar Rashdan, have built two radio telescopes. One of them now observed its first light, while the other will follow soon. The two telescope will be mounted on the roof of the Niels Bohr Building, to be used for student projects in the future.

- W5: Pillars of Star FormationHow do stars form? Images of the star forming region W5 like those in the infrared by NASA's Wide Field Infrared Survey Explorer (WISE, later NEOWISE) satellite provide clear clues with indications that massive stars near the center of empty cavities are older than stars near the edges
