Ephemeral Snapshots of Solar Eclipses

Though solar eclipses can happen two to five times a year, total solar eclipses with the Sun fully covered by the Moon are rare. The total solar eclipse of 22nd July 2009 was a once-in-a-century event because it lasted so long – 6 minutes and 39 seconds; an event not to be surpassed until at least June 2132. If you missed it, here are some incredible pictures from this rare occurrence.

A solar eclipse almost literally takes place when the stars align, that is to say when the Moon passes between the Earth and the Sun, covering the Sun fully or partially. In addition, it occurs only during a new moon when the Sun and the Moon are in conjunction, meaning they appear closer from Earth than they really are.

Wednesday’s total solar eclipse was only visible from a narrow corridor of countries around the world, namely the northern parts of the Maldives, India, Bangladesh, Philippines, Myanmar, eastern Nepal, central China and Bhutan, as well as the Pacific Ocean.

In other parts of the world, at least a partial solar eclipse was visible; still very stunning as the following pictures show.

Let’s see how the July 22 solar eclipse compares to other recent ones.

The solar eclipse on August 11, 1999 was an annular solar eclipse, meaning the apparent size of the moon was smaller than that of the Sun, making a red ring (or annulus) appear around the moon.

Because solar eclipses have been observed throughout the ages, different cultures have tracked them and attached religious significance or auspiciousness to them. In India, for example, it is customary to take a bath in one of the holy rivers to wash away one’s sins during a solar eclipse.

Probably since the 1999 eclipse, which was visible from a densely-populated area of the Earth, solar eclipse watching or hunting has become extremely popular, with people throwing parties or even travelling many hundreds of miles to view the event. Though the spectacle may only last minutes, we can definitely understand the hype around this stellar event, whose aftereffects on viewers can last months or even years.
