James Webb Space Telescope
Astronomers have produced the most detailed map of dark matter to date using NASA's James Webb Space Telescope, revealing how this invisible substance shaped the formation of galaxies and planets. The research, involving teams from Durham University, NASA's Jet Propulsion Laboratory, and Switzerland's École Polytechnique Fédéral de Lausanne, was published in Nature Astronomy. The map highlights dark matter's gravitational role in pulling ordinary matter together since the universe's early days.

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.
Observations from the James Webb Space Telescope suggest the presence of enormous stars in a distant early universe galaxy. These potential Population III stars could reach masses up to 10,000 times that of the sun. The findings may explain the origins of supermassive black holes.

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.
