Ningaloo Eclipse

On April 20, 2023, people saw the Ningaloo Eclipse. Due to the curvature of the earth's surface and the transition from an annular to a total eclipse, it is a rare 'hybrid solar eclipse'.
The following one won't show up until 2031, the last of which was spotted in 2013.

What are the Key Aspects of the Hybrid Solar Eclipse?

Australia, Timor-Leste, and Indonesia's West and Papua provinces were able to see the total solar eclipse.
Southeast Asia, the East Indies, Australia, the Philippines, and New Zealand all witnessed a partial solar eclipse at the same time. India could not see it.
The region of western Australia from which the eclipse was best visible had already been given the name of Ningaloo due to its singularity.
Additionally, the Ningaloo region has been listed as a UNESCO World Heritage Site.

What is a Solar Eclipse?

A solar eclipse is a phenomena that happens when the Moon moves in front of the Sun and the Earth, creating a shadow on the planet's surface and temporarily dimming the Sun.
The umbra, or central zone, and the penumbra, or outside region, make up the moon's shadow.

types of solar eclipses:

Total Solar Eclipse: When the Moon passes directly between the Earth and the Sun, fully obstructing the Sun, a total eclipse occurs.
A total solar eclipse or annular solar eclipse causes a phenomena called the Baily's Beads effect, commonly referred to as the diamond ring effect.
An annular eclipse occurs when the Moon is furthest away from the Earth.
Only a tiny ring-like sliver of light emanating from the sun's disc is visible due to the way it is obscured. The ring of flames is the name for this structure.
When the Moon is partially eclipsed, it does so when it is partially aligned with the Sun when it passes between the Earth and the Sun.
So, only a portion of the Sun appears to be obscured.
Due to the viewer's position in relation to the Moon's shadow, a hybrid solar eclipse happens when the eclipse is total from certain spots on Earth but annular from others.
