The highly irregular galaxy ESO 174-1, which resembles a lonely, hazy cloud against a backdrop of bright stars, dominates this image from the NASA/ESA Hubble Space Telescope. ESO 174-1 lies around 11 million light-years from ...
The universe is expanding, but how fast exactly? The answer appears to depend on whether you estimate the cosmic expansion rate—referred to as the Hubble's constant, or H0—based on the echo of the Big Bang (the cosmic ...
The universe is peppered with galaxies, which, on large scales, exhibit a filamentary pattern, referred to as the cosmic web. This heterogeneous distribution of cosmic material is in some ways like blueberries in a muffin ...
This image from the NASA/ESA Hubble Space Telescope features the galaxy LEDA 48062 in the constellation Perseus.
Using the Australia Telescope Compact Array (ATCA), an international team of astronomers has observed the population of submillimeter galaxies in a protocluster known as SPT 2349-56. As a result, they found a radio-loud active ...
In 1916, Einstein finished his theory of general relativity, which describes how gravitational forces alter the curvature of spacetime. Among other things, this theory predicted that the universe is expanding, which was confirmed ...
The James Webb Space Telescope Early Release Science (ERS) program—first released on July 12th, 2022—has proven to be a treasure trove of scientific finds and breakthroughs. Among the many areas of research it is enabling, ...
In celebration of Halloween, Hubble brings you this inky image of the galaxy cluster Abell 611, located over 1000 megaparsecs, or roughly 3.2 billion light years, from Earth. Like all galaxy clusters, the continued existence ...
Astrophysicists have performed a powerful new analysis that places the most precise limits yet on the composition and evolution of the universe. With this analysis, dubbed Pantheon+, cosmologists find themselves at a crossroads.
An international team of astronomers has conducted radio and optical observations of a peculiar giant radio galaxy known as GRG-J223301+131502. Results of the observational campaign shed more light on the properties of this ...
