Ultralight dark matter could explain early black hole formation

A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. There are two main types of black hole; stellar mass and supermassive black holes, and they differ in size, formation, ...

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 ...

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.

Jets from powerful black holes can point astronomers toward where to look for life in the universe

One of the most powerful objects in the universe is a radio quasar—a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by its gravitational pull, or burn up from ...

Dark matter could make planets spin faster

Dark matter is a confounding concept that teeters on the leading edges of cosmology and physics. We don't know what it is or how exactly it fits into our understanding of the universe. We only know that its unseen mass is ...
