![]() When the umbra’s diameter decreases, it creates a V-shaped shadow core, and if it falls on Earth, it creates an annular solar eclipse. In the case of the antumbra, it can only cause annular solar eclipses. When it comes to the penumbra, it is responsible for the partial solar eclipse, partial lunar eclipse, and the penumbral lunar eclipse. Total eclipses are among the rarest types of eclipse, and apart from them, the umbra may is responsible for a partial eclipse. If a celestial body, such as the Earth, enters the Moon’s shadow, then we will experience a solar eclipse however, if the Moon travels through Earth’s shadow, we will witness a lunar eclipse.Įvery category of the eclipse depends upon the type of shadow which is cast upon a celestial object. The penumbra is the outer part of a shadow, while the antumbra is the shadow that begins where the umbra ends. If an observer is standing inside the antumbra during an annular solar eclipse, that person will be able to see the edge of the Sun’s disk as a “ring of fire” around the Moon. We can witness the light source’s outer rim around the object casting the shadow in the antumbra. The antumbra is the lighter part, and it solely exists if the light source has a larger diameter than the opaque object. The umbra is the darkest and central part of the shadow. This shadow has three different areas, the umbra, antumbra, and penumbra. ![]() ![]() The Antumbra ShadowĪny opaque object illuminated by a light source will create a shadow into space. Let’s see exactly what an antumbra shadow is and how it creates annular solar eclipses. The antumbra is the lighter part of a shadow, similar to the penumbra however, it forms at a certain distance from the object casting the shadow. The other two types of shadows, the umbra, and antumbra create three different types of eclipses. The antumbra shadow is the only area of a shadow responsible for just one type of eclipse, namely the annular solar eclipse.
