"Millions are being captivated by a rare total lunar eclipse that is rising around the world tonight. Sky watchers are amazed as the full moon turns red, known as a 'Blood Moon'. During a total lunar eclipse, Earth lines up between the moon and the sun, hiding the moon from sunlight. As a result, the moon will turn a deep, dark red - hence the 'blood moon' title."
"It takes place when the Earth lies directly between the sun and the moon, and the moon is in the shadow of Earth. For a total lunar eclipse to happen, all three bodies must lie in a straight line. 'When this happens, the only light that reaches the moon's surface is from the edges of the Earth's atmosphere,' Royal Museums Greenwich explained. 'The air molecules from Earth's atmosphere scatter out most of the blue light."
A rare total lunar eclipse causes the full moon to pass fully into Earth's shadow, turning it a deep red and earning the name 'Blood Moon'. The phenomenon occurs when Earth lies directly between the sun and moon so that only sunlight refracted by Earth's atmosphere reaches the lunar surface. Blue wavelengths scatter out, leaving red light to illuminate the moon. In the UK the eclipse peaks at 19:33 BST and ends at 21:55 BST, but visibility depends on moonrise and a low horizon position. Observers are advised to seek high, eastern-facing vantage points, such as hills or rooftop viewing spots, and can view the event safely without eye protection.
