Red skies: 'Blood moon' and bright Mars on the rise

Longest lunar eclipse to take place on Friday

Nigeria: 'Nigerians Can See Blood Moon Tomorrow From 6:44pm to 9:21pm'

This lunar eclipse will also feature the longest blood moon that the Earth has witnessed in 100 years.

While lunar eclipse are more common to see than solar eclipses, the length of Friday's eclipse is unique and is just a few minutes shy of the longest lunar eclipse ever. The total eclipse will last 1 hour 42 minutes and 57 seconds.

The partial eclipse begins at 12:24 p.m. MDT with the full eclipse going from 1:30 p.m.to 3:13 p.m. Mars is also at its closest approach to Earth this week since 2003, making it appear bigger and brighter.

Whether a full moon turns coppery red depends entirely on the atmospheric conditions and how much dust is in the air to bounce off the light from the sun.

It noted that there would be total lunar eclipse on July 27, 2018 and January 21, 2019; partial lunar eclipse on July 16/17, 2019; transit mercury eclipse on November 21, 2019; and penumbral lunar eclipse January 10, 2020.

When the moon moves into the conical shadow of the earth, it goes from being illuminated by the sun to being dark.

Lunar eclipses occur as the moon passes through Earth's shadow. Stay with us to witness the rare phenomenon of the 21st century as we show the LIVE streaming of Chandra Grahan or Lunar Eclipse 2018. During this period, the total lunar eclipse will commence at 9:30PM and end at 11:3PM. Those who live in Asia and Australia will be able to see the eclipse between midnight and sunrise on July 28.

Scientists detect an underground lake filled with liquid water on Mars
"So, if there's a boundary between air and ice, or ice and dust, or ice and water , we get a reflection back", Stuurman said . Even if this new discovery is validated, experts are lukewarm about whether this body of water would be suitable for life.

According to Dr Duncan Steel from the Centre for Space Science Technology, total lunar eclipses in NZ occur roughly once every three years, whereas partial lunar eclipses are more common, happening roughly every year and a half.

"At this time, the moon passes into the shadow of the Earth, blocking the light from the sun".

In fact, in the Book of Revelation chapter 6 verses 11 - 13, where verse 12 says: "And I beheld when he had opened the sixth seal, and, lo, there was a great natural disaster; and the sun became black as sackcloth of hair, and the moon became as blood".

Dr Gregory Brown, of the Royal Observatory Greenwich, said: "We miss a section of the eclipse due to the moon being below our horizon when it starts". This is why the moon will appear red during the eclipse, and is therefore sometimes nicknamed a "blood moon".

"If Earth partially blocks the sun, and the darkest part of its shadow falls across the moon's surface, it is called a partial eclipse".

Mr Scagell said: "You may see this very eerie-looking deep-red moon rising".
