James Webb Space Telescope
A new study proposes that hypothetical dark stars, powered by dark matter, could account for three surprising observations from the James Webb Space Telescope in the early universe. These include ultra-bright blue monster galaxies, overmassive black holes, and mysterious little red dots. Researchers suggest these exotic stars formed quickly after the Big Bang and seeded supermassive black holes.

Scientists using the James Webb Space Telescope have produced the highest-resolution map of dark matter to date, based on distortions in 250,000 galaxies. This map uncovers previously unseen cosmic structures and could deepen understanding of the universe's evolution. The achievement highlights dark matter's dominant role, comprising 85 percent of the universe's matter.
Astronomers have a narrow window in February 2026 to observe asteroid 2024 YR4 using the James Webb Space Telescope, which could raise its impact odds on the moon from 4 percent to over 30 percent. The asteroid, discovered late last year, poses risks to satellites from potential lunar debris. This observation may determine if deflection missions are needed before a 2032 collision.

Astronomers have discovered phosphine gas in the atmosphere of the brown dwarf Wolf 1130C using the James Webb Space Telescope. This finding, led by researchers at the University of California San Diego, challenges expectations as phosphine has been absent in similar objects. The detection could reveal insights into phosphorus chemistry in low-metal environments.
