Starwatch: red marvel that is a lunar eclipse

Friday's red moon comes as part of the longest total lunar eclipse of the century.

However, during a lunar eclipse the glow from the moon is not almost as strong.

Mostly a lunar eclipse occurs twice or thrice a year, but this one will be rare owing to its long duration and visibility from globally.

The entire celestial event will last more than six hours, according to NASA.

The lunar eclipse will begin about 3.15 am (AEST) Saturday, July 28.

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".

Andrew Batchelor, founder of Dundee Culture, said: "The longest lunar eclipse this century takes place on Friday". Although U.S. residents won't be able to see the eclipse, there's still a reason to be excited. The moon will turn into a dark glowing red disc, which is from the sun's rays passing through Earth's atmosphere and being filtered by it.

According to the reports in ANI, the moon will be in ideal alignment with the sun and the earth, with the moon in the middle of the earth and the sun.

After this, the moon will get deeper and deeper into the earths shadow.

"This smaller and slower-moving full moon takes more time to cross the Earth's shadow than does a full moon that is closer to Earth and moving faster in orbit". This part of the eclipse is known as the penumbral eclipse, as the Moon is under partial influence of the shadow cast by the Earth (called Umbra). Additionally, if they wait a few more months, they'll be able to witness a combo of a total lunar eclipse and Supermoon on January 21st, 2019. It is safe to look at a lunar eclipse. Even after all these years, scientists are still learning about the moon from lunar eclipses. The Lunar Reconnaissance Orbiter, NASA's robotic spacecraft orbiting the moon, will experience it first-hand. If an area of the moon's surface is flat, it will cool quickly.

Protective eyewear was recommended during the recent solar eclipse to protect people's eyes from the sun's bright light. The corona is the sun's top layer.

The last time Mars was bigger and brighter than this was in 2003, when it was less than 56 million kilometres away from Earth.
