A rare type of solar eclipse is taking place this week across large parts of the world, as the Sun, Moon and Earth align.
The total annular solar eclipse takes place when the moon is too far away in its orbit of the Earth to completely block out the sun, causing light to appear around the edges of the moon.
The name annular is derived from the Latin word for ring and the effect it creates has been referred to by astronomers as a "ring of fire".
It takes several minutes for the moon to pass in front of the sun but the total eclipse lasts less than a second.
The path of the annular solar eclipse takes it across Africa, Central Asia and South East Asia on Sunday, 21 June.
Nasa has made a map of its trajectory, showing where the annular phase of the eclipse will be visible, weather permitting.
A second solar eclipse is set to take place on 14 December this year across South America, the Atlantic and Pacific Oceans, Antarctica and Africa.
It will be a total solar eclipse, meaning the moon will completely block out the sun and cast a shadow across the Earth.
