NOAA's GOES-16 satellite captured the sun blast a "huge rush of mass" that warped the magnetic field, according to the ...

In a new paper published in Physical Review X, researchers present compelling evidence for a “helicity barrier”—a previously ...

Sunspots are the most striking phenomenon of the solar magnetic field. After the invention of the telescope early in the 17th ...

Some exoplanets in their stars' habitable zones may be distinctly uninhabitable due to solar flaring. Red dwarfs are known for powerful flaring, and since they're dim and their habitable zones are ...

While the Sun appears placid to the naked eye, it is a roiling sphere of ionized gas or plasma, shaped by powerful magnetic ...

A close-in exoplanet is triggering stellar flares and self-destructing. This is the first direct evidence of planet-star ...

The flares may heat up and inflate the planet's atmosphere, which is dominated by hydrogen and helium. Being lashed by these ...

And soon, a group of scientists can say they have. A UK-led space mission will see astronomers blot out the Sun by using a ...

Essentially, the helicity "barrier" alters turbulent dissipation, changing how fluctuations dissipate and how the plasma is heated. The team has now analyzed data from the Parker Solar Probe, and it ...

Historically, Earth's rotation has been slowing down over millions of years. Around 1 to 2 billion years ago, a day lasted ...

Parker Solar Probe flying in front of the sun The solar atmosphere, or corona, is far hotter than the Sun's surface, a ...

A planet that is snuggled up closely with its host star may be igniting colossal flares that strip it of its own mass.
