The ring of fire, also known as the diamond ring or Baily's beads, is a feature of solar eclipses that occurs when the Moon covers the Sun and beads of sunlight shine through the Moon's rugged topography. The term "diamond ring" is used when only one or two beads remain, creating a ring of shining "diamonds" around the Moon.
An annular eclipse is a type of solar eclipse that occurs when the Moon's apparent size is not large enough to completely block out the Sun, resulting in the Sun appearing as a bright ring around the Moon. The word "annular" comes from the Latin word anulus, which means "ring".
Solar eclipses occur when the Moon passes between the Earth and the Sun, and the alignment of the three celestial bodies must be almost perfect
