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 […]

Using the Very Large Telescope (VLT), astronomers have discovered a compact binary system consisting of two white dwarfs in the center of a nearby globular cluster designated NGC 6397. The finding was presented in a […]

For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically expect […]

Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver important information regarding the […]

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields remain poorly understood. Recently, researchers at McGill University […]
