A 'ring of fire' occurs when the moon comes in front of the sun in a way that the Sun's light sneaks from behind, in the shape of a ring. The 'ring of fire' for this year is all set to arrive this Sunday, on June 21, 2020. As per astronomers, the event is highly anticipated because it is coinciding with the summer solstice. In the last 40 years, such a coincidence has happened only twice, so it makes all the more special.
