What is a lunar eclipse?

A lunar eclipse is one of the most spectacular sights the night sky has to offer. As the Moon slips into Earth’s shadow, the normally pale white Moon is turned a deep shade of red, and it can stay that way for a long time.

Lunar eclipses can be either partial or total, just like solar eclipses, and they only occur during one phase of the moon: the full moon.

As opposed to one solar eclipsewhere the moon falls between the earth and the sun, “lunar eclipses occur when the moon passes right behind it Earth and in the shadows of the earth,” Dhara Patel, a space expert at the UK’s National Space Center in Leicester, told Live Science. “That means they always happen on a full moon,” Patel said (a full moon occurs when the moon is on). the opposite side of the earth Sun).

Why is a lunar eclipse red?

When the Moon is in Earth’s shadow, our planet blocks sunlight from reaching the Moon’s surface directly. It would be natural to think that we could not see the moon at all during this time. “But because Earth has an atmosphere, red light is diffracted onto the moon,” Patel said, “that’s why lunar eclipses tend to be this blood-red color.”
