The star that transforms into a red supergiant does so at a cost. It loses a large percentage of its mass out to space. As a result, while red supergiants are counted as the largest stars in the universe, they are not the most massive because they lose mass as they age, even as th...
galaxies: clusters: generalcosmology: theorydark matterThe Einstein radius plays a central role in lens studies as it characterizes the strength of gravitational lensing. In particular, the distribution of Einstein radii near the upper cut-off should probe the probability distribution of the largest ...
TheBOSSis named after theBaryon Oscillation Spectroscopic Survey—an international effort to map galaxies and quasars in the early universe—and is like cosmic webbing. This wall is made up of 830 separate galaxies that gravity has corralled into four superclusters, connected by massive filaments of...
A Hungarian-US team of astronomers have found what appears to be the largest feature in the observable universe: a ring of nine gamma ray bursts – and hence galaxies - 5 billion light years across. The scientists, led by Prof Lajos Balazs of Konkoly Observatory in Budapest, report their wo...
Earlier such images had used galaxies to map the universe and were only able to go seven billion years back in time.The map could find the answer to the puzzles of how the universe expanded and may give clues to the nature of dark energy. Scientists from the Sloan Digital Survey studied ...
Instead, the large star-filled objects clump together in a web, and this is the large-scale structure of the universe, according to ESO. Scientists working with the Very Large Telescope found that the rotation of the quasars is parallel to the large-scale structures where the galaxies are ...

Galaxy clusters, known as the largest self-gravitating objects in the universe, are home to a vast expanse of high-temperature gas. This gas emits brilliant X-rays, making these clusters visible. When these colossal clusters merge, it culminates in an astronomical event of unmatched magnitude, ...
Magnifying The Universe: Interactive Journey from the Smallest Particles to the Largest Galaxies By Dr. Winston Ewert Published: Jun 16, 2022 Updated: Jul 28, 2023 Zoom in and out for fun, or stop and read, the choice is yours. We take you from the smallest known things in the universe...
That may sound chilly and tenuous, but it means the cloud is five times hotter and 10 to 100 times denser than what's typical in galaxies like the Milky Way, researchers said. In addition to shedding light on the early universe, the huge vapor cloud also reveals some important information...
