Only this year total solar eclipse will take place tomorrow morning, plunging parts of Antarctica into darkness for two minutes, NASA said.
The rare sight of the moon blocking the sun reaches its greatest extent around 07:33 GMT for viewers on the edge of Antarctica Ronne ice tray.
The eclipse will be a brief respite from the long summer day Antarctica has been experiencing since October — in fact, the sun won’t set there again until April.
While this may be largely missed, viewers elsewhere in the Southern Hemisphere, including parts of Australia, Chile and New Zealand, will see a partial eclipse.
Solar eclipses only occur about every six months, because the moon doesn’t revolve around the Earth in quite the same plane as it does around the sun.
In addition, total solar eclipses are about three times rarer and seen only by those in the 60-160 mile wide path of the moon’s shadow.
The next total solar eclipse will not occur until April 8, 2024 but, unlike Saturday’s event, will be widely visible in parts of Canada, Mexico and the United States.
Meanwhile, a total solar eclipse is not expected in Europe this century.

SAFELY WATCHING A SOLAR Eclipse
It is never safe to look directly at the sun, even if the sun is partially or mostly eclipsed.
When viewing a partial eclipse, you must wear solar or eclipse goggles during the entire eclipse if you want to look at the sun.
Sunglasses or eclipse glasses are NOT regular sunglasses.
Regular sunglasses are not safe to look at the sun.
If you are in the path of a total solar eclipse, you can only take off your solar or eclipse glasses if the moon completely blocks the sun.
If you don’t have sunglasses or eclipse glasses, you can use an alternative indirect method, such as a pinhole projector.
Pinhole projectors should not be used to look directly at the sun, but to project sunlight onto a surface.
Solar eclipses occur when the moon passes between the Earth and the sun, casting a shadow on the Earth. There are several types, depending on how much of the sun appears obscured in a particular location to a viewer.
For a total solar eclipse, all three celestial bodies must be in a straight line.
Viewers see the sky getting very dark, as if it were sunrise or sunset, while also being able to glimpse the sun’s corona, or outer atmosphere, around the moon.
The corona is normally obscured by the bright face of the sun.
A similar phenomenon, an annual solar eclipse, occurs when the moon appears slightly smaller than the sun, does not block it completely, leaving what is known as an ‘annular ring’ around it at the time of the greatest eclipse.
The next annular solar eclipse will cross North America on October 14, 2023.
While tomorrow’s total eclipse is likely to be nearly unappreciated, many locations in the Southern Hemisphere will still be in for a treat, NASA explained.
“In some places, viewers will not see the total eclipse, but will instead experience a partial eclipse,” the statement said. blog post.
This happens when the sun, moon and Earth are not exactly aligned. The sun will appear to have a dark shadow on only part of its surface, and daylight will only be affected if more than 80 percent of the sun’s surface is obscured.
“Viewers in parts of Saint Helena, Namibia, Lesotho, South Africa, South Georgia and Sandwich Islands, Crozet Islands, Falkland Islands, Chile, New Zealand and Australia will see a partial eclipse on Dec. 4,” the space agency added. to.
For onlookers in Australia, Hobart will experience the largest solar eclipse of any capital city, but at most 11 percent of the solar surface will be obscured.
In Melbourne this figure will drop to just two percent, while in Canberra the phenomenon will be barely visible as the sun will cross the horizon at the time of the maximum eclipse.
New Zealand’s South Island will see a similar light show, with just four percent of the sun obscured for viewers in Invercargill and 0.7 percent to the north in Queenstown.

While tomorrow’s eclipse will be largely missed in Antarctica (pictured), viewers elsewhere in the hemisphere, including parts of Australia, Chile and New Zealand, will see a partial eclipse
NASA warned that for many of these locations, the partial eclipse will occur around the time of sunrise or sunset.
Accordingly, viewers wishing to observe the event will need to have a clear view of the horizon in order to actually see the eclipse.
Weather permitting, NASA plans to livestream a view of the total solar eclipse as seen from Antarctica’s Union Glacier, both on YouTube and the NASA website.
The stream — provided by the JM Pasachoff Antarctic Expedition — will begin on December 4 at 1:30 AM EST (6:30 AM GMT) and will run until 3:37 AM EST (8:37 AM GMT).
Totality starts at 2:44 am EST (7:44 am GMT).
WHEN WILL THE NEXT SUN REFRESHES TAKE PLACE?
The next solar eclipse in the US will take place on April 8, 2024, from Texas to Maine, with the Canadian city of Montreal also able to see the totality.
The next total solar eclipse after that will occur on August 12, 2026 and will be seen from the Arctic, Greenland, Iceland, Spain and northeastern Portugal.

On September 2, 2035, a large number of people in China, northern Japan and Korea will witness a total solar eclipse.
Australia will experience the greatest number of total solar eclipses between 2023 and 2038: between April 20, 2023 and December 26, 2038, five eclipses will be visible from the continent.
