When you look up at the sky on a sunny day, the sun might seem like a bright spot, unchanging in the sky. But the sun is a ...
Just as the amplified magnetic field peaked, these electrons settled again, locking in the strong field’s direction. Benjamin Weiss, an MIT professor and study co-author, explains the process like ...
Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those fields formed so fast. Observations from the Atacama Large ...
As black holes feed, they pull material into a disk around them. The material orbiting in this disk gets heated to extreme temperatures, and so it becomes a plasma — a state of matter in which some of ...

Astronomers just mapped a hidden magnetic 'flip' threading the Milky Way — a reversal in the galaxy’s field no one knew was there
Somewhere between us and the Sagittarius Arm, the Milky Way’s magnetic field quietly switches direction. A team of radio ...
Numerical simulations provide a mechanism that explains how celestial objects such as stars and galaxies can generate ordered, macroscopic magnetic fields. The mechanism arises from turbulence — ...
Scientists have shown that changing magnetic fields in precise ways can create exotic quantum matter that does not normally ...
It’s well established that the universe is expanding, but there’s serious disagreement among scientists over how fast it’s happening. Two of our best ways of measuring the cosmic expansion rate, the ...
Astronomers have uncovered a strange magnetic “flip” hidden inside the Milky Way. Using a new radio telescope, researchers ...
