A lunar eclipse occurs when the Moon passes through the Earth's shadow. There are three types of lunar eclipses - total, partial, and penumbral - depending on how much of the Moon passes through the Earth's umbra or penumbra. During a total lunar eclipse, the Moon takes on a red color due to refraction of sunlight through the Earth's atmosphere. A solar eclipse occurs when the Moon passes between the Earth and the Sun, casting its shadow on parts of Earth. There are also three types of solar eclipses - total, partial, and annular - depending on the Moon's position and alignment with the Earth and Sun.
Moon is said to be the only natural satellite of the Earth. While there are many such satellites in the solar system it has the uniqueness of being the same size as the object around which it orbits.

The Sky
Astronomy is about us. As we learn about astronomy, we learn about ourselves. We search for an answer to the question “What are we?” The quick answer is that we are thinking creatures living on a planet that circles a star we call the sun. In this chapter, we begin trying to understand that answer. What does it mean to live on a planet?
The preceding chapter gave us a quick overview of the universe, and chapters later in the book will discuss the details. This chapter and the next help us understand what the universe looks like seen from the surface of our spinning planet.
But appearances are deceiving. We will see in Chapter 4 how difficult it has been for humanity to understand what we see in the #sky every day. In fact, we will discover that modern science was born when people tried to understand the appearance of the sky.
A "lunar eclipse" and a "solar eclipse" refer to events involving three celestial bodies: the Sun ("solar"), the moon ("lunar"), and the Earth. A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow obscures the moon or a portion of it. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun.

Moon Phases:
The moon's phases refer to the different appearances of the moon as observed from Earth during its orbit around our planet. These phases are primarily determined by the relative positions of the Earth, the moon, and the sun. As the moon orbits the Earth, different portions of its surface are illuminated by sunlight, resulting in the various phases we observe.
1. New Moon:
The new moon occurs when the moon is positioned between the Earth and the sun, with its illuminated side facing away from Earth. From our perspective, the moon appears dark and invisible in the night sky. This marks the beginning of a new lunar cycle.
2. Waxing Crescent:
Following the new moon, a small sliver of the moon becomes visible as sunlight gradually illuminates its surface. This phase is known as the waxing crescent. It appears as a thin crescent shape in the western sky after sunset.
3. First Quarter:
During the first quarter phase, the moon has completed approximately one-quarter of its orbit around the Earth. Half of the moon's surface is illuminated by sunlight, creating a half-moon shape. This phase is often referred to as the waxing half or the half moon.
4. Waxing Gibbous:
As the moon continues to orbit, more of its surface becomes illuminated by sunlight. The waxing gibbous phase occurs when the illuminated portion of the moon is greater than half but not yet full. It appears as a bulging, almost full moon in the night sky.
5. Full Moon:
The full moon occurs when the Earth is positioned directly between the sun and the moon, with the moon's entire illuminated side facing Earth. This phase marks the midpoint of the lunar cycle and is characterized by a fully illuminated, round shape. The full moon is often associated with cultural and religious significance and is the brightest phase of the lunar cycle.
6. Waning Gibbous:
Following the full moon, the moon begins to wane or decrease in illumination. The waning gibbous phase occurs when the illuminated portion of the moon is greater than half but gradually diminishing. It appears as a shrinking, nearly full moon in the night sky.
7. Third Quarter:
During the third quarter phase, the moon has completed approximately three-quarters of its orbit around the Earth. Half of the moon's surface is illuminated, but this time, the opposite half compared to the first quarter phase. It is often referred to as the waning half or the half moon.
8. Waning Crescent:
The waning crescent phase marks the final stage of the lunar cycle before the new moon. Only a small portion of the moon's surface is illuminated by sunlight, appearing as a thin crescent shape in the eastern sky before sunrise. This phase gradually transitions into the new moon, completing the lunar cycle.
These phases repeat in a continuous cycle, with each complete cycle lasting approximately 29.5 days, known as a synodic month. The moon's phases have significant cultural, religious, and scientific importance,

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Eclipse presentation[1]
1. Lunar Eclipse When Earth casts a shadow on the Moon, Earth blocks the Sun’s light from the Moon. Total Lunar Eclipse – occurs when the Moon passes completely into the umbra. Partial Lunar Eclipse – occurs when the Moon does not fully enter the umbra Penumbral Eclipse – occurs when the Moon passes through only the penumbra. They are hardly noticeable because the shadow of the Moon is very faint. A lunar eclipse can occur only during a full moon.
2. This image shows a complete transition during a lunar eclipse. Notice that the phase of the moon is "full." Totality lasts about 1 hour 4 minutes
3. Lunar Eclipse Types The types depend on what portion of the Earth's shadows the Moon interacts with
4. A Total Lunar Eclipse is not completely dark!! Refracted " Red " makes it through the Earth's Atmosphere, The " Bluer " colors are refracted more and do not make it through the atmosphere. The moon often does not totally disappear during a total lunar eclipse. Instead it can be seen as a very dark red color because of the refraction of sunlight through the Earth's atmosphere .
5. Solar Eclipse When the Moon comes between the Sun and Earth, the Moon blocks the Sun’s light and casts a shadow on Earth. A solar eclipse can occur only during a new moon. Total Solar Eclipse – occurs if you are at a spot within the Moon’s umbra. Partial Solar Eclipse – is visible if you are just outside the Moon’s umbra but still in the penumbra.
6. Partial Solar Eclipse A Partial Solar Eclipse also may occur when the Moon is not quite in line with the Earth-Sun line and therefore cannot block all of the Sun from view. When this happens, only part of the penumbra reaches Earth and the umbra does not touch Earth at all, but is off to its side in space.
7. Annular Solar Eclipse Annular Solar Eclipse – occurs when the Moon is farthest from earth in its orbit, resulting in the apparent size of the Moon being slightly less than that of the Sun.
8. There is another important factor to consider: the Moon's inclined orbit shifts, rather like the rim of a spinning coin just before it comes to rest. This means that the line of nodes slowly rotates in the opposite direction to the Moon's movement, an effect called the regression of the nodes. Why the path of totality changes with each total solar eclipse
