Last Solar Eclipse 2021 livestream: The last solar eclipse or surya grahan of the year 2021 will occur on Saturday, December 4. It can be noted that a solar eclipse happens when the Moon moves between the Sun and Earth, casting a shadow on Earth, fully or partially blocking the Sun's light in some areas. For a total solar eclipse to take place, the Sun, Moon, and Earth must be in a direct line, according to NASA. The solar eclipse will not be visible from India while some people in the Southern Hemisphere will have the chance to experience a total or partial eclipse of the Sun on December 4.

The only place where this total solar eclipse can be seen is Antarctica, as per the information provided by NASA. In some places, while viewers won't get to see the total solar eclipse, they'll instead experience a partial solar eclipse. This happens when the Sun, Moon, and Earth are not exactly lined up. The Sun will appear to have a dark shadow on only part of its surface. People 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 solar eclipse on December 4.

According to NASA, in many of these locations, the eclipse will occur before, during, and after sunrise or sunset.

How to safely watch a total or partial solar eclipse

It is never safe to look directly at the Sun, even if the Sun is partly or mostly obscured. When viewing a partial solar eclipse, you must wear solar viewing or eclipse glasses throughout the entire eclipse if you want to face the Sun. It can be noted that solar viewing or eclipses glasses are not regular sunglasses and regular sunglasses are not safe for viewing the Sun.
