This is a long exposure image of the January 2019 lunar eclipse taken from Picacho Peak in southern Arizona. The combined light of all sunrises and sunsets casts the moon in a red color. The strong haze present is from lots of high clouds which threatened to obscure the eclipse at the time of capture, but instead added some nice flair.

BLOOD RED MOON ECLIPSE
SURI
Good morning!
Would like to know all about the BLOOD RED MOON ECLIPSE please!
Google Gemini
A Blood Moon is the term for a total lunar eclipse when the Moon takes on a red, orange, or coppery hue. This astronomical event occurs when the Earth passes directly between the Sun and the Moon, casting its shadow on the lunar surface. 🌎🌕☀️
How it Happens
The reddish color is not a result of a supernatural event but rather a natural phenomenon explained by science. During a total lunar eclipse, the Moon is in Earth's darkest shadow, called the umbra. However, it doesn't disappear completely. Instead, a small amount of sunlight filters through Earth's atmosphere, and our atmosphere scatters the blue light, a process known as Rayleigh scattering.
This leaves the longer, red and orange wavelengths of light to pass through and refract, or bend, toward the Moon's surface. The more dust, volcanic ash, or clouds in the atmosphere, the redder and darker the Moon will appear. The same process is responsible for the red and orange colors we see during sunrises and sunsets.
Types of Lunar Eclipses
Not all lunar eclipses are the same. There are three main types, which depend on how the Sun, Earth, and Moon align:
Total Lunar Eclipse:
This is when the Moon passes completely into the umbra, the darkest part of Earth's shadow. This is when the "Blood Moon" effect occurs.
Partial Lunar Eclipse:
In this type, only a portion of the Moon enters the umbra. It will look like a "bite" has been taken out of the Moon.
Penumbral Lunar Eclipse:
This is the most subtle type, where the Moon passes through the outer, fainter part of Earth's shadow, the penumbra. The Moon will only appear slightly darker than usual, and it can be difficult to notice without a keen eye.
The blood moon phenomenon, while historically associated with various myths and omens in different cultures, is today a reminder of the beautiful cosmic dance between our planet, its Moon, and the Sun.

Does it affect the earth and the human beings in any way?
Google Gemini
A total lunar eclipse, or "Blood Moon," has no known physical effects on Earth or on human beings. While the event is dramatic and can be viewed by anyone on the night side of Earth without special equipment, it doesn't cause any physical harm or changes.
Effects on Earth
During a lunar eclipse, the gravitational forces of the Sun and Moon still influence Earth, but their combined effect is very small. The Moon's gravity causes ocean tides, but a lunar eclipse doesn't significantly alter this because the Moon is still there, its mass hasn't changed, and it's still exerting its gravitational pull. Any gravitational changes are minimal and not noticeable to humans.
Effects on Humans
Any reported effects on humans, such as changes in mood, behavior, or sleep patterns, are not scientifically supported. Instead, these are considered psychological, or psychosomatic, effects. ðŸ§
Psychological Impact:
The dramatic nature and cultural significance of a total lunar eclipse can make people feel a sense of awe or excitement. This can lead to staying up late to watch the event, which may disrupt sleep and lead to fatigue or restlessness.
Safety:
Unlike a solar eclipse, which can cause eye damage if you look directly at the Sun, a lunar eclipse is completely safe to observe with the naked eye. The Moon is simply reflecting filtered sunlight and poses no danger.
Cultural Beliefs:
Many cultures have historically associated lunar eclipses with myths, omens, or superstitions. These beliefs can lead to people changing their behavior during an eclipse, such as fasting or performing certain rituals, but there's no scientific evidence that these actions are necessary for health or safety.
