Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe. Their progenitors, protoclusters, show these galaxies in their infancy, offering a window to study how ...
Astronomers from Serbia and Russia have conducted deep optical observations of a cloud of neutral atomic hydrogen, designated FAST J0139+4328. Results of the observational campaign, published December 31 on the arXiv preprint ...
After combing through NASA's James Webb Space Telescope's archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample of galaxies that have ...
Astronomers have captured the most detailed look yet at faraway galaxies at the peak of their youth, an active time when the adolescent galaxies were fervently producing new stars.
Scientists at the University of Missouri have identified a small group of unusual objects in the early universe. Using NASA's James Webb Space Telescope (JWST), Haojing Yan and his team at Mizzou's College of Arts and Science ...
An international team of astronomers has uncovered multiple evolutionary paths for the universe's most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion stars, show that less than ...
Nearly every galaxy has a supermassive black hole in its core. Whether the black hole forms first and then the galaxy around it—or the other way around—is still a matter of some debate, but we know the evolution of both are ...
Mid-infrared observations from NASA's James Webb Space Telescope, shown in white, gray, and red, are combined here with X-ray data from NASA's Chandra X-ray Observatory, highlighted in blue. Together, these different wavelengths ...
Using the Australian Square Kilometer Array Pathfinder (ASKAP), an international team of astronomers has discovered a spectacular bipolar outflow from the disk of a nearby galaxy known as ESO 130-G012. The finding was reported ...
By analyzing the archival data from the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has inspected the outflow of a nearby galaxy known as NGC 1266. Results of the new study, presented ...
