'Blood moon' treat for stargazers

'Blood moon' treat for stargazers
The Moon turned orange during the total lunar eclipse yesterday, as seen here with the Toronto skyline. The eclipse is also known as a "blood moon" due to the Moon's colour as it passes into Earth's shadow.

WASHINGTON - Stargazers in the Americas and Asia were treated to a lunar eclipse yesterday, a celestial show that bathed the Moon in a reddish tint to create a "blood moon".

But unfortunately for Singaporeans, enthusiasts who had gathered for an Astronomical Society of Singapore observation at Labrador Park were left disappointed because the view was affected by the haze.

In Hong Kong, free viewing locations were set up on a harbourside promenade by the Hong Kong Space Museum for the public to observe the various phases on telescopes.

In Tokyo, enthusiasts performed yoga exercises under the blood moon. Many also climbed atop the city's skyscrapers to view the sky.

However, on Australia's eastern coast, a live video feed set up by the Sydney Observatory was hit by cloud cover, thwarting some viewers.

During a total lunar eclipse, light beams into Earth's shadow, filling it with a coppery glow that gives it a red hue.

This eclipse was the second of four total lunar eclipses, which started with a first "blood moon" on April 15, in a series astronomers call a tetrad. The next two total lunar eclipses will be on April 4 and Sept 28 next year.

The last time a tetrad took place was in 2003-2004, with the next predicted for 2032-2033. In total, the 21st century will see eight tetrads.
