Earth awaits longest blood moon

Earth awaits longest blood moon

A lunar eclipse occurs when the Moon passes within Earth's umbra, or shadow, which appears to "cover" part of the orb, turning it a deep shade of red.

Total lunar eclipses are referred to as "Blood Moons" because they often appear dark red in color. Friday's will be long, lasting 1 hour and 43 minutes. Only partially see him in the Eastern part of South America. The total lunar eclipse is projected to last for an hour and 42 minutes, with the entire event lasting over 6 hours. Lunar eclipses happen when the moon passes behind the Earth into its shadow.

"The total lunar eclipse will be fully visible in Thiruvananthapuram". In addition, on July 27, the Moon will be at the most distant from the Earth distance. The reddish hue of the Moon is because the earth has an atmosphere and when the sun's light reaches the atmosphere, gases in the air actually scatter or bend the light.

During the total eclipse, which begins at 7:30am, the Moon will be much fainter than usual.

However, during a lunar eclipse the glow from the moon is not almost as strong. As the Moon continues to move towards the centre of the Earth's shadow, and then away from it, red light will bounce off its surface in different proportions. While some tabloids have predicted the lunar eclipse will mean some tragic event or even the end of the world, there is not cause for concern.

The first event to create a habitable environment on the Moon could be four billion years ago when a proto-Earth collided with some other body and ended up forming the Earth and the Moon. Viewers in a somewhat wider chunk of the planet, including both China and South America, might get a glimpse of the eclipse as the moon rises or sets.

The two planets will be just 57.6 million km apart on July 31, while Mars will appear brightest on July 27-30, making it easier to be seen with telescope or the naked eye. The moon will take on a red or brown colour during a selenelion because it will be eclipsed by the earth.

- From Whanganui to Wellington there's a chance of seeing the totally-eclipsed Moon as the Sun peeks above the horizon.

The super blue blood moon was covered by cloud for many Kiwis. As a result, the sunlight will be blocked from reaching the moon's surface and will cast a shadow over it.

Now's the time to catch Mars in the night sky.

You can see it all around the globe, but the best view will be reserved for the Eastern Hemisphere - New Zealand, Australia, Asia, Europe, and Africa.

When you live in a city, the trick is to find the biggest bit of sky you can, or get up as high as you can above the rooftops.
