Earth is set to experience its first eclipse of the year on April 30. A solar eclipse will occur when the new Moon passes in front of the Sun, blocking the sunlight. The first eclipse of the year will be partial as the Moon will only block a fraction of sunlight.
According to Nasa, during the April 30 eclipse, 64 per cent of the sun's disk will be blocked by the Moon as seen from Earth. The eclipse is partial, also, due to the fact that the Moon, the Sun, and Earth will not be aligned in a perfect straight line. The Moon will cast only the outer part of its shadow, which is known as the penumbra.
