Galaxies die earlier than expected: Webb sees signs of halted star formation 700 million years after Big Bang An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by models.

Sagittarius C: Webb provides closest look yet at one of Milky Way's most extreme environments Sagittarius C is one of the most extreme environments in the Milky Way galaxy. This cloudy region of space sits about 200 light-years from the supermassive black hole at the center of our galaxy. Here, a massive and dense cloud of interstellar gas and dust has collapsed on itself over millions of years to form thousands of new stars.

Webb explores effect of strong magnetic fields on star formation Follow-up research on a 2023 image of the Sagittarius C stellar nursery in the heart of our Milky Way galaxy, captured by NASA's James Webb Space Telescope, has revealed ejections from still-forming protostars and insights into the impact of strong magnetic fields on interstellar gas and the life cycle of stars.

Supernova archaeology: Finding clues in the ruins of an ancient dead star with Chandra People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space.
