In the sprawling Hydra constellation, 137 million light-years away, lies NGC 3285B—a dazzling spiral galaxy recently ...
The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars.
The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it's sensed light from a ...
The James Webb Space Telescope could target tiny and bright galaxies in the early universe to unveil some secrets about the universe's most mysterious stuff, dark matter.
Yet, in 2023, the JWST spotted a shocking number of large and bright galaxies just 500 million years after the Big Bang, when the universe was only around 3% of its current age of 13.8 billion years.
Stars and galaxies are shown in the bright white points of light, while the more diffuse dark matter and gas are shown in purples and reds. Aaron M. Geller, Northwestern, CIERA + IT-RCDS.
Strangely bright galaxies spotted by the James Webb Space Telescope (JWST), called “little red dots”, may have more stars packed into them than any other galaxies we know of.
Even though the remaining galaxies aren’t wildly bright any more, they are still much more numerous than expected. There are roughly twice as many massive galaxies found as had been predicted.
A composite of Stephan’s Quintet, a visual grouping of five galaxies, constructed from almost 1,000 separate image files from the James Webb Space Telescope. UCLA astrophysicists believe if cold ...
Jan 31, 2024: Bright galaxies put dark matter to the test (Nanowerk News) For the past year and a half, the James Webb Space Telescope has delivered astonishing images of distant galaxies formed not ...
