The partial solar eclipse over Brewster, New York on March 29, 2025.

The Down Under is about to witness a partial solar eclipse as the moon comes between the sun and Earth to obscure a portion of our solar system's blazing star.

While the Northern Hemisphere was treated to the celestial phenomenon most recently in March, now it's the bottom half of the world's turn for a partial solar eclipse. The looming cosmic show also follows a recent total lunar eclipse that dazzled in Europe, Africa, Asia and Australia earlier in September.

So, yes, that means if you're reading this from the U.S., you're probably going to miss seeing the upcoming eclipse in person – also the last of its kind for 2025. In fact, only about 16 million people, or 0.2% of the Earth’s population, are in its path.

Here's everything to know about the partial solar eclipse.

What is a solar eclipse?

A solar eclipse is what occurs when the moon comes in between the sun and the Earth.

During the total solar eclipse in April 2024, spectators in the path of totality witnessed a stunning sight as the Earth, sun and moon perfectly aligned for a few minutes. The rare process not only ushered in uncharacteristic darkness, but unveiled the outermost layer of the sun's atmosphere.

But spectators in some states outside the path of totality were still treated to a partial solar eclipse, which is what will be visible Sunday, Sept. 21.

A partial solar eclipse is what happens when the moon imperfectly passes between the sun and Earth.

Will partial solar eclipse be visible in US?

Sorry, but no.

Though parts of the U.S. were treated to a partial solar eclipse in March, this time around, it will only be visible on the Southern Hemisphere. Australia – which includes New Zealand – and Antarctica are the only two continents to get a view of the eclipse, which will also pass over the Pacific and Atlantic oceans over various islands, according to NASA.

What time is the partial solar eclipse?

In general, the partial solar eclipse will begin at 1:29 p.m. ET Sunday, Sept. 21, which will be Monday local time on the bottom of the world. The maximum eclipse phase, when the moon covers the largest portion of the sun, will occur at 3:41 p.m. ET, according to Space.com.

Exact timings, though, will depend on a spectator's precise location. Visit the website Time and Date for a more detailed breakdown.

What will happen Sept. 21?

Instead of unveiling the sun's signature circular ring, as occurs during a total solar eclipse, the moon will only partly cover the sun, giving it a crescent shape, according to NASA. The sight will resemble someone taking a bite out of the sun.
