A diamond ring that occurs when the Moon moves in between the Earth and the Sun.
An eclipse occurs when two astronomical bodies go in front of each other. The most famous one occurs when the Moon goes right in front of the Sun’s disk to cause a solar eclipse. Right before and after totality, for a few seconds a beautiful “diamond ring” appears when just a few rays are still getting through. Totality lasts for only a few minutes. During that time, the Sun’s faint halo and gas streams emanating from the surface become visible because the sun’s bright light is completely blocked. The sky gets dark during an eclipse and stars become visible also.
