Coronal loops, well-defined hot strands of plasma that arch out into the sun’s atmosphere, are iconic to the sun’s imagery. But many of the supposed coronal loops we see might not be there at all.

Fast solar winds originating from the sun can have direct impacts on Earth – disrupting systems like GPS, aviation, ...

Fine grained structures have been detected in the sun’s outer corona. In a paper published on July 18 in The Astrophysical Journal, a team of scientists led by Craig DeForest — solar physicist at ...

The banana-size solar flares could lead to a better understanding of high-energy solar physics. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

A METHOD of determining the large scale structure of the coronal and interplanetary magnetic fields has recently been described 1. The model originated as an attempt to explain the observed large ...

We present the results of a detailed numerical simulation of the circumstellar environment around three exoplanet-hosting stars. A state-of-the-art global magnetohydrodynamic (MHD) model is considered ...

Many coronal loops -- ropey strands of plasma that scientists have long thought existed in the sun's atmosphere -- may actually be optical illusions, according to a new paper that challenges ...

In 1610, Galileo redesigned the telescope and discovered Jupiter's four largest moons. Nearly 400 years later, NASA's Hubble Space Telescope used its powerful optics to look deep into space -- ...
