Stars are uniform spheres, but only to first order. The way in which stellar rotation and magnetism break this symmetry places important observational constraints on stellar magnetic fields, and ...

"Studies of magnetic fields in massive stars in galaxies with young stellar populations provide crucial information on the role of magnetic fields in star formation in the early universe." When you ...

A study extends the definition of a habitable zone for planets to include their star's magnetic field. Interest in Earth-like planets orbiting within the habitable zone of their host stars has surged, ...

Middle-aged stars can experience their own kind of midlife crisis, experiencing dramatic breaks in their activity and rotation rates at about the same age as our Sun, according to new research ...

Our planet is doomed. In a few billion years, the sun will exhaust its hydrogen fuel and swell into a red giant — a star so big it will scorch, blacken and swallow up the inner planets. While red ...

The Einstein Probe space telescope has captured a powerful X-ray outburst from a nearby K-type star, offering a rare, high-resolution look at how stellar magnetic fields unleash sudden bursts of ...

The great majority of exoplanets discovered so far are orbiting cool, low-mass stars whose properties are relatively similar to the Sun. However, the stellar magnetism of these stars can be ...

The original version of this story appeared in Quanta Magazine. Our planet is doomed. In a few billion years, the sun will exhaust its hydrogen fuel and swell into a red giant—a star so big it will ...

Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own Jupiter, according to a new study by a team of astrophysicists. It is the first time the ...

Shedding light on why some massive stars have magnetic fields even though these stars’ interiors layers don’t undergo convection, researchers report observational evidence that magnetic fields form in ...

In the vastness of the known universe, few things are more wondrous than a magnetar. These stars are deceptively pint-sized; they squeeze multiple suns’ worth of mass into an orb no bigger than a city ...
