The whole phenomenon is only visible from Antarctica, but astronomers in other parts of the Southern Hemisphere, including Chile, New Zealand and parts of Australia, can experience a partial eclipse of the sun.
There will be this week Only one total solar eclipse this year, But it is only known from Antarctica, according to Information From NASA. The event will take place next Saturday, December 4th. It will reach Its maximum magnitude at 07:33 GMT for visitors near the Filchner-Ronne ice sheet on the Antarctic continent.
However, astronomers in other parts of the Southern Hemisphere – including some parts Chile, New Zealand, Australia, Namibia, Lesotho, South Africa, the British Isles of St. Helena, southern Georgia and the South Sandwich Islands, the Crochet Islands and the Falkland Islands – all can experience partial eclipses. In most of these places, this event occurs before, during and after sunrise or sunset, which means visitors must have a clear view of the horizon to see it.
The next total solar eclipse will occur on April 8, 2024 and is widely known in Canada, Mexico and the United States. No such astronomical events were expected in Europe this century.
When does a solar eclipse occur?
When a solar eclipse occurs The moon is located between the sun and the earth, Casts a shadow over it, blocking the star’s light completely or partially in some parts of our planet, the US space agency said.
For a total solar eclipse to occur, the sun, moon, and earth must be aligned. When the natural satellite is placed in front of our planet the observer at the center of its shadow can see the entire eclipse. At the time, The sky is very dark, like sunrise or sunset. If weather conditions allow, those in the path of a total eclipse can see the solar corona, i.e. the sun’s outer atmosphere, otherwise obscured by the star’s brightness.
How to observe the event?
NASA warns that it is never safe to look directly at the sun, even if it is partially or largely obscured. To do this, it is necessary to wear sunglasses or eclipse goggles (they are not ordinary sunglasses) Throughout the event. If you are in the path of a total solar eclipse, you can only remove your solar vision or eclipse glasses when the moon is completely blocking the sun.
If solar or eclipse goggles are not available, an alternative method is a Pinhole projector, Which does not see the star directly, but is used to direct sunlight onto a surface.
In addition, if weather permits, NASA will broadcast footage of a total solar eclipse from the Union Glacier in Antarctica.
