At www.jpl.nasa.gov/news/news.php?release=2014-440 … we have this picture of the Sun
X-rays streaming off the Sun. This is the first picture of the Sun by NASAs nuclear spectroscopic telescope array (NuSTAR). It was designed to look into deep space in order to study x-rays from black holes and supernovas etc. It was launced in 2012 but only now has it been turned around to focus on the Sun.
At the moment we are in the middle of solar cycle 24 so there is a lot of noise – or activity. It is thought that as the Sun cycle becomes quieter over the next few years even better images will be possible.
