NASA’s James Webb Space Telescope has revealed an ancient galaxy cluster with an unexpectedly dense concentration of dark matter, challenging theories about how the universe developed. The discovery also uncovered a surprising connection between scattered starlight and invisible dark matter that could transform how astronomers study the early cosmos.
Galaxies warp and multiply as if in a house of mirrors in this image from NASA’s James Webb Space Telescope released on Sept. 29, 2026. The brilliant golden galaxies seen here are part of a galaxy cluster called MACS J0454.1-0300. The orange galaxies bunched together on one side of the image, however, are not actually […]
Diligent sleuthing by astronomers uncovered a surprising chemical clue that indicates the white dwarf star HS 0209+0832 may host a second-generation planet. This artist’s concept released on Oct. 5, 2026, depicts that possible explanation. The white dwarf is the “dead” core of a star that burned through all of its nuclear fuel and lost its outer […]
Galaxies, vast collections of billions of stars, gas, and dust held together by gravity, are scattered across the immensity of space. But every so often, a coincidence occurs: Two galaxies line up from our point of view on Earth (or from a space telescope) and appear to overlap in the sky. These rare overlapping galaxies […]
Her new album ‘The Meaning of Flowers’ tackles much more than just flora, as the Danish musician and composer explores the sounds and sentiments of the very beginning of human life.
