A blood moon is coming! Here's what you need to know

28 Juillet 2018

At 2:43 am, the total eclipse will end.

Speaking to JOE, David Moore, Chairman for Astronomy Ireland said: "We'll only see half of the eclipse in Ireland".

As commented by the National Center for Hydro Meteorological Forecasting, a successful observation of this rare lunar eclipse, along with the blood moon, requires the absolutely clear sky.

Dr Brown said: "At this time, the moon passes into the shadow of the Earth, blocking the light from the sun". As mentioned above, the moon will also fall under the region over which the earth casts its shadow.

Unlike with solar eclipses, you need no special equipment to observe lunar eclipses.

The Moon receives its "blood red" colour from a scientific phenomenon called Rayleigh scattering.

Director, B.M. Birla Science Centre, Dr B.G. Siddharth said, "First will be the penumbral eclipse, invisible to many".

Huzzah, all you fans of astral bonanzas and the nearby cosmos for this weekend the Earth shall witness the longest total lunar eclipse of the 21st century. An eclipse does not occur on every full moon because the moon's plane is tilted at an angle to that of the earth's. During Friday's eclipse, the moon will be passing nearly directly through the middle of the shadow, maximizing the time that moon spends in darkness.

In a lovely coincidence, on July 27, Mars will also appear large and bright in the sky as it moves towards its closest approach to Earth in 15 years.

Fortunately, Indians will be able to watch the total eclipse from start to finish. Atmospheres, similar to glass lenses, can refract sunlight.

Its appearance near the blood moon after sunset will give viewers a double vision in red. Many observers try to measure the precise extent of the Umbra during eclipses by timing the passage of its edge across identifiable Lunar features such as craters. Says Noton. "The latter is hard, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison".

"We should have a coppery red tint on the moon with Mars the "Red Planet" just next to it, very bright and with a slight orange hue itself", he said.

The phenomenon, known as perihelic opposition, will make the red planet appear larger and brighter than normal in the night sky. The same principle causes the early-evening sky to remain relatively bright, even though the Sun is below the horizon.

"They will move through reasonably quickly but if that coincides with the peak moment of the eclipse, they could obscure the moon".

To see the lunar eclipse better, you can use telescopes or binoculars. The moon will exit the secondary shadow, or penumbra, at 1:28 am on July 28.

During the total eclipse, which begins at 7:30am, the Moon will be much fainter than usual. It will last for 103 minutes, making it the longest eclipse of the 21st century.

- In Invercargill there will be five minutes between sunrise at 8:12 and moonset shortly thereafter, with the Moon entirely within Earth's shadow.

At 02:45 am Total Eclipse ends. The level of darkness is often described in terms of the Danjon Scale. Check out for a tracker of the best action for your location. Both of these Eclipses will be total.

However, this latest research paper lists a series of arguments showing that life could have endured on the lunar surface and not be immediately wiped off four billion and 3.5 billion years ago. For the best view, find a dark spot away from light pollution. It is expected to be the longest lunar eclipse witnessed in 100 years.
