That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion remains hotly debated, even challenging the standard model of cosmology. A research […]

An international collaboration using the Low Frequency Array (LOFAR) has published an exceptionally detailed radio sky map, revealing 13.7 million cosmic sources and delivering the most complete census yet of actively growing supermassive black holes. […]

The KM3NeT collaboration is a large research group involved in the operation of a neutrino telescope network in the deep Mediterranean Sea, with the aim of detecting high-energy neutrino events. These are rare and fleeting […]

In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible—low-surface-brightness galaxies dominated by dark matter and containing only a sparse […]

Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun’s outer atmosphere, using one of nature’s rarest events as their window: total solar eclipses. Drawing on more than […]

An international team of astronomers has performed multi-wavelength observations of the nearby Araish galaxy to investigate the origin of its radio emission. As a result, they detected an extended radio jet of this galaxy. The […]

Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years […]

A team of 48 astronomers from 14 countries, led by the University of Massachusetts Amherst, has discovered a population of dusty, star-forming galaxies at the far edges of the universe that formed only a billion […]

Astrophysicists from the University of Waterloo have observed a new jellyfish galaxy, the most distant one of its kind ever captured. Jellyfish galaxies are named for the long, tentacle-like streams that trail behind them. They […]

Dark energy is one of those cosmological features that we are still learning about. While we can’t see it directly, we can most famously observe its effects on the universe—primarily how it is causing the […]
