Dramatic 'half-blood' moon as New Zealand sees start of partial lunar eclipse

Dramatic 'half-blood' moon as New Zealand sees start of partial lunar eclipse

Lunar eclipses occur when the Earth lines up between the sun and the moon.

A penumbral lunar eclipse occurs when the Moon doesn't fall in the umbra at all and is always present in the penumbra.

A partial lunar eclipse could be visible from the United Kingdom on Tuesday, 50 years to the day since the USA mission to put men on the Moon lifted off.

United Kingdom watchers will need a clear view of the southeastern and southern horizon in order to spot the low moon during the eclipse. We will have to wait till May 26, 2021 for the next one when a total lunar eclipse will be visible from parts of the western U.S., Australia, western South America and southeast Asia, according to timeanddate.com.

The lunar eclipse happens when the Earth moves between the Sun and the Moon.

The eclipse takes place when Earth passes between the sun and the moon, but the three celestial bodies are not perfectly aligned.

What is a partial lunar eclipse? In India, the "Penumbral eclipse" begins shortly after midnight of July 16, i.e. 0013 hrs on Wednesday July 17.

North American were not quite happy, since this was the only area in which people were not able to see the eclipse.

What is a partial lunar eclipse?

From the United Kingdom, the eclipse should kick off between 9pm and 10pm.

This year's lunar eclipse holds added importance because it is the last eclipse of the year and coincides with one of the most important days for the scientific community - the launch of mankind's first mission on the Moon.

Stronger atmospheric scattering of blue light means that the light that reaches the lunar surface is predominantly red, so for observers on Earth the eclipsed part of the Moon may be rust-coloured, red, or sometimes dark grey, depending on conditions. This deepest stage of the eclipse will take place at 21:30 UTC, when the dark red-brown umbra will cover the northern 65 percent of the moon's diameter.

The voyage ended four days later when United States astronaut Neil Armstrong became the first man to step on to the Moon's surface.

The Moon herself - or himself, suit yourself - is getting in on the Apollo 11 anniversary action by putting on an early morning show.

The "Earthrise" photograph of Earth above a lifeless moon is said to have changed human perceptions of our shared humanity and the need to treat all life with respect and care.
