<p>The European Space Agency's (ESA) and NASA's Solar Orbiter have captured images of the Sun in unprecedented detail.</p>

<p>Spacecraft took the images on March 7, as it passed directly between the Earth and Sun at a distance of 75 million kilometres, on the halfway point between the Earth and its parent star, according to an ESA statement.</p>

Mysterious vortex waves discovered on the Sun travelling faster than expected</a></strong></p>

<p>Among the images, taken by the Extreme Ultraviolet Imager (EUI), is the highest resolution image ever taken of the Sun's full disc and outer atmosphere, the corona.</p>

<p>The Spectral Imaging of Coronal Environment (SPICE) instrument captured the first image of a full Sun -- the first of its kind in more than 50 years. Lyman-beta wavelength ultraviolet radiation emitted by hydrogen gas was used to capture the image.</p>

<p>To capture the entirety of the Sun with the high-resolution telescope at EUI, a mosaic of 25 individual pictures would need to be taken at that close distance. Since each tile takes about 10 minutes, including the time required for the spacecraft to move from one segment to the next, the full image was acquired over a period of more than four hours.</p>
