X-rays stream off the Sun NASAs Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first picture of the sun. “The NuSTAR data, seen in green and blue, reveal solar high-energy emission (green shows energies between 2 and 3 kiloelectron volts, and blue shows energies between 3 and 5 kiloelectron volts). The high-energy X-rays come from gas heated to above 3 million degrees. The red channel represents ultraviolet light captured by SDO at wavelengths of 171 angstroms, and shows the presence of lower-temperature material in the solar atmosphere at 1 million degrees.” Source: jpl.nasa.gov/spaceimages/details.php?id=pia18906 #nasa #nustar #sun #xrat
