Sky gazers and scientists have all been counting down to witness today"s annular solar eclipse which will pass over parts of the Americas. A solar eclipse is nothing more than an alignment of the Sun, Earth and Moon that has the Earth passing through the Moon"s shadow. But why is the solar eclipse in today"s image different? It occurs when the Moon is farthest from the Earth because of its elliptical orbit. When this happens, it appears smaller, letting the sun"s brilliance peek through and creating a halo—the "Ring of fire". Viewers in specific regions can witness this cosmic show, but please be cautious. This eclipse should not be looked at directly without wearing specialised eye protection.
