NuSTAR: The most sensitive solar portrait ever taken in high-energy X-rays.

Tags: , , , |

For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun. NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first picture of the sun, producing the most sensitive solar

Supercomputer Simulation of Magnetic Field Loops on the Sun

Magnetic fields emerging from below the surface of the sun influence the solar wind—a stream of particles that blows continuously from the sun’s atmosphere through the solar system. Researchers at NASA and its university partners are using high-fidelity computer simulations to learn how these magnetic fields emerge, heat the sun’s outer atmosphere and produce sunspots

Composite Map of Far and Near Solar Hemispheres. Line-of-sight magnetic field in the Sun's near hemisphere is rendered in blue-gray, in Gauss. Seismic map of the Sun's far hemisphere is rendered in yellow. The far-side seismic image maps a phase shift between solar acoustic noise with periods of about five minutes embarking into the
