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.

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 ...

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 ...

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 -- ...
