This Friday, July 27, there will be a total lunar eclipse from 7:15 pm to 1:28 am on Saturday, (which would be one of the longest eclipses). The eclipse will be visible to the naked eye all over Umvoti, in many parts of South Africa and around the world.
The moon does not have its own light but shines because its surface reflects the sun's rays. During a total eclipse, the Earth enters the sun and the moon and blocks any direct sunlight from reaching the moon. The sun casts the shadow of the Earth on the surface of the moon
For this to happen, the sun, the Earth and the moon must be roughly aligned if the Earth can not project the shadow on the surface of the moon. directly reaching the surface of the moon during a total lunar eclipse, the moon is still visible to the naked eye. This is because the earth's atmosphere bends sunlight and indirectly illuminates the surface of the moon.
When light pbades through the Earth's atmosphere, it refracts to the surface of the Earth and its colors are scattered and filtered. , while the rest, the colors with longer wavelengths like orange and red, go through the atmosphere.
This light is once again refracted towards the surface of the moon completely eclipsed, thus illuminating it in a reddish-orange glow. For this reason, a total lunar eclipse is sometimes colloquially called a blood moon.
In addition, Venus, Jupiter, Saturn and Mars will be more visible than usual.
If a reader takes a picture of the Blood Moon please email it to the Greytown Gazette for publication next week.
