The James Webb Space Telescope investigated low-mass galaxies from the early universe, finding most of these dwarf galaxies' light drove a vital phase of cosmic evolution.
With the help of a magnifying glass 4 million lightyears wide, astronomers may have solved the riddle of what burned away the hydrogen fog that pervaded the early universe.
Astronomers using the James Webb Space Telescope (JWST) have discovered a massive galaxy that's so old its existence should be impossible, posing a challenge to current theoretical models on dark matter. As detailed in a new study published in the journal Nature, the so-called quiescent galaxy, ZF-UDS-7329, contains more stars than the Milky Way — […]
For the first time since its discovery, scientists have found stars within the Magellanic Stream, a mighty river of hydrogen gas emanating from two small galaxies in the outskirts of the Milky Way.
