A small group of young researchers at the Cosmic Dawn Center, Niels Bohr Institute, University of Copenhagen, have, through ...

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...

An inexplicably hot, fast-growing cluster of galaxies in the early universe has scientists questioning theories of galactic ...

HOUSTON—NASA’s SPHEREx observatory completed the first of four planned all-sky surveys in 102 infrared wavelengths as 2025 neared its end to help answer some key astrophysical questions about the ...

The universe may have been born out of nothing, with an "anti-universe" twin where time runs in the opposite direction—rather than exploding from an infinitely small and dense point, or "singularity." ...

With the spectacular ability of the James Webb Space Telescope, the earliest ever-known supernova was tracked back to the very dawn of the universe. This supernova is, in fact, the first in a long ...

New research suggests the universe may be lopsided. Cosmic microwave background and galaxy data hint at directional differences, challenging cosmology’s assumption of uniformity and standard ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

NASA’s SPHEREx telescope has combined 100+ infrared maps into the universe’s first all-sky cosmic atlas, revealing galaxies, interstellar clouds, and cosmic inflation patterns never seen before.
