3176 - MOON - eclipse turns red?

  -  3176   -  MOON  -   eclipse turns red?  The only total lunar eclipse of the year will light up the sky this Wednesday, May 26, 2021, when the full moon, a supermoon due to the satellite's nearness to Earth,  passes through Earth's shadow. During this lunar eclipse, the face of the moon will turn a brick-red hue.


- -----------------------  3176   -  MOON  -   eclipse turns red?

-  The fiery glow is the most dramatic of the three types of lunar eclipses, the other two are called partial and penumbral. A total lunar eclipse happens only when the sun, Earth and moon are perfectly lined up. 

-

-  When enters the outer portion of Earth's shadow, becoming totally bathed in the darkest part of that shadow, why isn't the result a "lights out" for the sky? Why instead does the moon become engulfed in a light-orange to blood-red glow? 

-

-  Picture yourself standing on the moon, looking down on Earth during the spectacular night-sky event. When the Earth is directly in front of the sun, blocking the sun's rays from lighting up the moon, you'd see a fiery rim encircling the planet. 

-

-  The darkened terrestrial disk is ringed by every sunrise and every sunset in the world, all at once. Even though our planet is way bigger than the sun, our home star's light bends around the edges of Earth. This light gets reflected onto the moon.

-

-  But not before it travels through our atmosphere, which filters out the shorter-wavelength blue light, leaving the reds and oranges unscathed to bathe the moon's surface. 

-

-  The moon will change various shades during different stages of a total lunar eclipse, going from an initial grayish to orange and amber. Atmospheric conditions can also affect the brightness of the colors. For instance, extra particles in the atmosphere, such as ash from a large wildfire or a recent volcanic eruption, may cause the moon to appear a darker shade of red. 

-

-   The moon doesn't always hide completely behind Earth's shadow. During partial lunar eclipses, the sun, Earth and moon are slightly off in their alignment, and so our planet's shadow engulfs just part of the moon.

-

-  You might not even notice the third type of lunar eclipse, the penumbral kind, in which the moon sits in Earth's penumbra, or its faint outer shadow.

-

-  Our 2021 total lunar eclipse is expected to be visible in Australia, parts of the western United States, western South America and Southeast Asia.   Other areas of the world, including the entire U.S., will be able to see at least some stages of the lunar eclipse, including its partial and penumbral phases. ------------------- Other reviews available:

-

-  3165   - WATER  -  on the moon, asteroids?  The moon has been considered a waterless world. However, a discovery has shown that at least some parts of the moon, such as the large, permanently shadowed craters at its poles, contain significant deposits of water. 

-

-  2936  -  MOON  -  facts from moon-watching?  -   If  you view the crescent moon seen from Mill Valley set behind Mount Tamalpais, Marin County, California, you see the brightness of the portion of the Moon not directly lit by the Sun, but instead illuminated by “Earthshine“. It will change over time, dependent on how reflective the Earth is, which is dependent on a number of factors, including cloud cover, ice cover, the time of day and the Earth's rotation, and even the seasons. 

-

-  2919  -  MOONS  -  in our solar system?  The discovery of moons around another planet left centuries’ worth of astronomers desperate to learn more about what other natural satellites the solar system holds. Increasingly powerful telescopes and interplanetary spacecraft have revealed that there are many of the moons in the solar system and they are far stranger than anyone could have imagined.

-

-  2527  -  MOON -  Take Me to the Moon. -  Twin astronauts, Mark Kelly and Scott Kelly, were part of a survival experiment. From March 2015 to March 2016 Scott spent a year on the International Space Station while his brother, Mark, remained on Earth.  In April 2019, the results of a 3 year study was published of what changed between them with the two different year experiences.  Can we survive on the Moon?

-  2791  -  MOON  -  measuring the distance?  -  The distance to the Moon is 240,000 miles.  I learned that in High School.  Today the average distance is measured to be 238,856 miles.  Actually that distance can be measured to within less than an inch.

-

-  2752  -  MOON  -  mining the Moon?   Forty-five years have passed since humans last set foot on an extraterrestrial body. Now, the moon is back at the center of efforts not only to explore space, but to create a permanent, independent space-faring society.

-

- 2450  -  MOON  -  new analysis 50 years later.  The Apollo missions brought back 200 pounds of rocks and soil samples.   Half of these samples were locked in a vacuumed safe to be analyzed 50 years later with more advanced scientific instruments.  New sample testing inspired these new theories about the formation of the Moon.
