What conditions are required for a lunar eclipse - For a lunar eclipse to occur there must be a full moon and at the same time, it should be at the lunar node. So that the Sun, the earth, and the moon are closely aligned in a straight line.

In this way, the full moon will pass through the shadow of the earth.

But, have you ever paid attention to know exactly what happens in the space that gives birth to the lunar eclipse? I mean, how does it happen? And what conditions are required for the lunar eclipse?

Let’s dive deep into it to know the real scenario.

How does a lunar eclipse happen? - What conditions are required for a lunar eclipse?

 It happens when the sun, the earth, and the moon align in a straight line, and the earth being in the middle blocks the sunlight from striking the moon’s surface directly and thus a shadow is formed which we call lunar eclipse.

We all know that the moon doesn’t have its own light. It shines by reflecting the sunlight from its surface. Therefore, when the Earth’s shadow blocks the sunlight from reaching the lunar surface, the moon’s surface gets dim and red in a few hours.

Such moons are termed blood moons!

Wait, if a full moon is required then why don’t we see it every month?

You caught me right but be clear, not just a full moon, it should be a full moon at its lunar node.

Remember! When the moon’s orbit forms an angle of 5 degrees with the earth’s orbit, the two orbital planes meet at a point called the lunar node.

Besides, these are quite admirable events for sky viewers worldwide. Have you ever experienced them? If not, get to know how often it happen so you don’t miss the next time it happens.

How often does a lunar eclipse happen?

On average, a lunar eclipse occurs twice a year. However, there may be three to five of them in one year.

But, these happen throughout the planet. If you stay at the same point, you’ll encounter it once in 2.5 years. Each lunar eclipse can be seen from either half of the earth.

When was the last lunar eclipse?

The last total lunar eclipse took place on 15-16 may, 2022 and was seen from different parts of America, Antarctica, Europe, and Africa.

Moreover, the next lunar eclipse is expected to happen on 8 November and will be seen in many portions of Asia, Australia, North and South America, and most parts of Europe.
