The lunar eclipse occurs in daylight in the Western Hemisphere, so people in North America will miss it.
Lunar eclipses can only occur during a full moon, and this one is special because it is also the blood of the moon. The moon will be in perfect agreement with the sun and the earth on Friday, with the moon on the opposite side of the earth from the sun.
The totality of this lunar eclipse will last approximately one hour and 43 minutes, but a partial eclipse before and after the total phase means that the moon will spend nearly four hours crossing the Earth's shadow
The Moon he moves into the shadows of the earth, he will darken, but he will not disappear. Sunlight flowing through the earth's atmosphere will dramatically illuminate and redden the moon. Depending on the weather conditions in your area, it can be rusty, brick-red or blood-red.
This happens because blue light experiences more atmospheric scattering, so that red light will be the most dominant color when sunlight flows through our atmosphere and hits the moon.
"The Moon is not always in perfect agreement with the Sun and the Earth Therefore, we do not get a lunar eclipse in any lunar cycle "said Brad Tucker, an astronomer from the Astronomy and Astrophysics Research School at the Australian National University. "You will see the sunrise and sunset of the Earth illuminating the surface of the Moon – over 350,000 km away – if you were on the Moon, you would see a total eclipse, as the Earth would block the sun." This full moon in July is also referred to as Full Buck Moon and Thunder Moon, when a male stag is in full growth and at a time of frequent thunderstorms, according to the Almanac of the Old Peasant. It is also a "mini moon" because the moon is farthest from Earth and appears small. The fact that the moon appears so small and takes longer to get through the shadow of the earth is also the reason why the eclipse takes longer.
Looking at the solar eclipse
Where can you see the total lunar eclipse?
People in Australia, New Zealand, Europe, Africa and Asia will have the best view, while the final phase of the solar eclipse will be visible after sunset in parts of South America.
For those in the Middle East and Madagascar, the solar eclipse will occur at midnight, and the people of Europe and Africa will have the best view between sunset and midnight. Asia, Indonesia and Australia will see it between midnight and Sunrise on Saturday.
North America, much of the Pacific Ocean and most of the Arctic I can not see anything. The entire US will not be able to see a complete lunar eclipse by January.
And unlike solar eclipses, especially the total solar eclipse in August 2017, the lunar eclipse is safe to see with the naked eye or binoculars.
Mars in the sky
Our red moon will have a company on Friday when Mars is closest to the Earth it is in 15 years.
Mars achieves its resistance when aligned on the opposite side of the Earth and the Sun. This happens at the same time that it will reach one of its closest points to Earth, about 35.9 million miles away. That's what makes it so bright in our skies early Friday morning.
While Mars will be overboard for people in Central Chile, South Africa and Australia, it will be low in the southern sky for those watching in the US and Europe.
"Despite its glorious size, the northern observers pay a price during this juicy Mars appearance, "Sky & Telescope contributing editor Bob King said. "For most peripheral oppositions, including this one, the planet retreats into the belly of the ecliptic in the southern sky."
Mars will have its closest access since 2003 on Monday and Tuesday, when it reaches 35.78 million miles. So, if bad weather on Friday disturbs your chance, there will be more opportunities. Experts estimate that the brightness of Mars lasts several weeks.
Although it will not look nearly as big as the Bloodmoon, Mars will be the greatest when you look through a telescope and close to its maximum brightness in our sky. Mars is safe to see even with the naked eye.
