- The longest total lunar eclipse or blood moon in a century will take place on the night of July 27th.
- From the moon, the Earth will appear surrounded by a circle of fire – with its sunset and its rising connected in a loop.
- NASA has an animation showing what might look like the bright red ring of the Earth during a total lunar eclipse
-
North America will not see the eclipse, but no matter who can watch via a live video broadcast. 19659006] A total lunar eclipse occurs when the Earth glides in front of the sun to project a red-orange to deep-red shadow on the moon.
That is why the astronomical event is often called blood moon. People in the eastern hemisphere of the Earth can see the longest lunar eclipse of the 21st century starting at 7:30 pm UT on Friday, July 27th.
However, imagine that you are an astronaut who lies on the surface of the moon during a total lunar eclipse, and you look at the house. What would you see?
The NASA Science Visualization Studio illustrated the answer to this question with an animated video.
At some one on the moon during a lunar eclipse, the Earth would seem to be surrounded by a bright red ring.
The above image is taken from the animation of NASA, which actually illustrates the precise appearance of the Earth and the Moon during the total lunar eclipse that s & # 39; 39; is produced on 27 September 2015.
But apart from the position of the terrestrial continents The lunar eclipse this week will appear more or less the same according to the perspective of the moon
Here's why.
Which gives total lunar eclipses an orange-red color
Total lunar eclipses and total solar eclipses are essentially the inverse of
However, their appearances are very different (as you observe them Earth or its natural satellite).
During a total solar eclipse, the Moon pbades between the Earth and the Earth. one, casting a small dark shadow on our planet. For those who look on Earth, the ring of sunlight surrounding the moon seems colorless because the moon does not have any atmosphere. (Atmospheres, similar to glbad lenses, can refract sunlight.)
The Earth is surrounded by an air cover, and this crystalline refraction is ultimately the reason why Lunar eclipses make the moon orange-red. in volume, about 80% of the Earth's atmosphere is made up of nitrogen gas, or N2, and most of the remainder is gaseous oxygen, or O2. Together, these gases take on the white light of the sun – a mix of all the colors of the spectrum – and disperse around the blue and purple colors. Human eyes are much more sensitive to bruises than to purples, which is why the sky is blue and the sun yellow during the day.
During sunset or sunrise, sunlight has gone through much more atmospheric gas, and this effectively filters the blue and makes the light orange or even red.
A similar thing happens during a lunar eclipse. The Earth's atmosphere bends and concentrates sunlight into a cone-shaped shadow, called the Umbel
The red color is never quite the same from a lunar eclipse to another. 19659007] "Pollution and dust in the lower atmosphere tend to tame the color of the rising or falling sun, while fine smoke particles or tiny aerosols coiled at high altitudes during a major volcanic eruption can deepen the color until the sun rises. to an intense red hue. " David Diner, a global scientist at NASA's Jet Propulsion Laboratory, wrote in a blog in 2010.
What the Earth looks like from the Moon during a total lunar eclipse
About 240,000 miles to the Moon »« If you were standing on the surface of the moon during a lunar eclipse, you would see the sun go down and get up behind the Earth, "wrote Diner. "You would observe the refracted and scattered solar rays that pbad through the atmosphere surrounding our planet."
On the moon, you would see the sunrise and sunset of Earth connected together in a loop of about 25,000 miles. And on the ground around you, normally the dull gray lunar dust, or regolith, would look a little orangey red.
The tinted shadow of the Earth is still there – if you had enough money and a spaceship, you could fly however, the moon 's slightly inclined orbit means that' s. it only crosses the shadow of our planet twice every 11 months
Where and when to see the total lunar eclipse of Friday
The upcoming eclipse will occur during that time 39, we call a "micro" moon – the opposite of a super moon. This occurs because the moon 's orbit is not perfectly circular, so it seems larger at times and smaller at others during its orbit of about 29 days around. of the earth. In this case, it will seem a little smaller.
North America will not have any luck during the lunar eclipse, since the moon will be below the horizon. You can still watch the phenomenon on a live webcast, however.
If weather cooperates, most of East Africa, the Middle East and Central Asia should see the complete lunar eclipse and total. Antarctic scientists should also have a magnificent view
Europe, East Asia, Australia, Indonesia and other parts of the world. Other regions will benefit from a partial lunar eclipse, where the moon pbades in part through the shadow of the Earth. The moon first touches the penumbra or the outer shadow of the Earth. According to NASA, this should happen at 17:14 GMT on July 27th.
The total eclipse – when the moon is fully inside the Earth's red ombra – starts at 7:30 pm and ends at 9:13 pm. UTAH. According to EarthSky, the partial eclipse will resume immediately after, as the moon begins to leave the Earth's shadow. The entire event will be finished at 23:28 UT (which could be technically early on July 28, depending on where you live).
