An "X-ray eye" designed to study distant galaxies and black holes has taken a remarkable photo of the Sun.

Nasa's Nuclear Spectroscopic Telescope Array (Nustar) was launched in 2012 to view the universe's high-energy X-rays.

It's hoped Nustar will help scientists better understand how the Sun works.

"Nustar will give us a unique look at the Sun, from the deepest to the highest parts of its atmosphere," said Prof Smith, a solar physicist at University of California, Santa Cruz.
