Lunar eclipse. A lunar eclipse is an astronomical event that occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. [1] Such an alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit.
Umbra (A) and penumbra (B) The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object. Assuming no diffraction, for a collimated beam (such as a point source) of light, only the umbra is cast. These names are most often used for the shadows cast by celestial bodies ...
A symbolic orbital diagram from the view of the Earth at the center, showing the Moon's two nodes where eclipses can occur. Up to three eclipses may occur during an eclipse season, a one- or two-month period that happens twice a year, around the time when the Sun is near the nodes of the Moon's orbit. An eclipse does not occur every month ...
Screen grab from Universe Odyssey on YouTube The answer: A total lunar eclipse, like the one happening this month on Sept. 27. Read on to learn what this red ring really is and why it's important.
A symbolic orbital diagram from the view of the Earth at the center, with the Sun and Moon projected upon the celestial sphere, showing the Moon's two nodes where eclipses can occur. An eclipse involving the Sun, Earth, and Moon can occur only when they are nearly in a straight line, allowing one to be hidden behind another, viewed from the third.
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of Earth, totally or partially. Such an alignment occurs approximately every six months, during the eclipse season in its new moon phase, when the Moon's orbital plane is closest to the plane of Earth's orbit. [1]
Baily's beads. The Baily's beads, diamond ring or more rarely double diamond ring effects, [1] are features of total and annular solar eclipses. Although caused by the same phenomenon, they are distinct events during these types of solar eclipses. As the Moon covers the Sun during a solar eclipse, the rugged topography of the lunar limb allows ...
Description Eclipse vs new or full moons, annotated.svg. English: A diagram illustrating the difference between a full moon and a lunar eclipse, and the difference between a new moon and a solar eclipse. This is caused by the 5° incline of the moon's orbital plane around earth, meaning that an eclipse can only happen when the moon is nearly in ...
