The longest total lunar eclipse of this century can be witnessed on Friday night and Saturday morning. Friday's will be long, lasting 1 hour and 43 minutes.
Now's the time to catch Mars in the night sky.
"Hence the appellation of "Blood Moon".
It is, however, expected that citizens of the areas from the central province of Thua Thien - Hue southwards are able to see this curious phenomenon if there will be no rain here.
But with cloudy skies across the Philippines forecast for the whole week and a southwest monsoon, weather forecasters are not optimistic Filipinos will get a good view of the eclipse.
The neighboring planet will appear unusually large and bright, a mere 57.7 million kilometers from Earth on its elliptical orbit around the sun.
As this theory goes, the super-heated doughnut of molten, vaporized rock and liquid - called a synestia - cooled, then the moon emerged, after which the remaining cloud of vapor condensed to form the Earth.
The reason for this is that the only light reaching the Moon will have been passed through the Earth's atmosphere.

The red color is never quite the same from one lunar eclipse to the next due to natural and human activities that affect Earth's atmosphere.
As the moon lines up with the Earth and the Sun, the moon will darken in colour switching from its silvery glow to a rustic, dark red colour.

The combination of a supermoon and total lunar eclipse creating a blood moon last occurred in 1982 and will not happen again until 2033.
Closer to home, researchers could conduct experiments in chambers that simulate the early lunar environment, to see whether microbial life could remain viable.
