Ningaloo Eclipse

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.
