Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...
Sunspots are dark regions on the Sun's surface (photosphere) approximately the size of Earth. They are formed by strong magnetic fields that emerge from the Sun's convective interior, becoming buoyant ...
Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The sun likes to remind us that Earth is merely one part of a joined ...
From the largest planets to comets, there are a variety of worlds in the Solar System that experience aurorae. On Earth, the Northern and Southern Lights are caused by electrically charged particles ...
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 ...
How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating ...
A radio signal has been detected, pointing to the possible existence of a magnetic field on YZ Ceti b, an exoplanet 12 ...
The magnetic fields that formed in the very early stages of the universe may have been billions of times weaker than a small fridge magnet, with strengths comparable to magnetism generated by neurons ...
A detailed suite of simulations conducted by astrophysicists at the Flatiron Institute and their collaborators showed that magnetic fields can produce black holes with masses that were previously ...
In 2008, Erez Ben-Yosef unearthed a piece of Iron Age "trash" and inadvertently revealed the strongest magnetic-field anomaly ever found. Ben-Yosef, an archaeologist at Tel Aviv University, had been ...
