Polarized light observations from ALMA reveal the magnetic structures and galactic outflows in Arp 220, the nearest ultraluminous infrared galaxy to Earth, providing detailed field maps.
Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...
Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...
The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...
New radio observations of the Milky Way are exposing hidden patterns in its magnetic field. People have scanned the night sky ...

Earth’s magnetic field flips often, and some reversals drag on 70,000 years
Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity flips, when magnetic north and south swap places, happen several times per ...
We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed ...
A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...
Electrons in a magnetic field can display striking behaviors, from the formation of discrete energy levels to the quantum Hall effect. These discoveries have shaped our understanding of quantum ...
Astronomers have captured the first view of polarized light and the magnetic fields that surround Sagittarius A* (Sgr A*), the supermassive black hole at the heart of the Milly Way. The new EHT ...
