For the 50th anniversary NASA has released some beautiful Panoramas pictures of Apollo missions.
As NASA has written on its blog/post it is never safe to look directly at the sun’s rays, even if the sun is partly obscured. It is very safe to wear eclipse glasses when you watch the Sun or want to face the Sun.
According to NASA “during the short time when the moon completely obscures the sun – known as the period of totality – it is safe to look directly at the star, but it’s crucial that you know when to take off and put back on your glasses”.
During the period of totality when the moon completely obscures the sun it is safe to look directly at the star, but it’s important that you know when to take off your sunglasses.
NASA explains as the moon moves in front of the sun, there comes a time when there is a single bright spot left – a bright spot that, in combination with the atmosphere of the sun still visible around the moon, looks like a giant diamond ring.
As the moon goes on to move, this bright spot may break up into several points of light that shine around the moon’s edges.
“Known as Baily’s Beads, these are light rays from the sun streaming through the valleys along the moon’s horizon. Baily’s Beads are very short-lived, and may not last long enough to be noticeable to all observers of the total solar eclipse. It is still not safe to look at the sun at this point! Only when these spots completely disappear can you safely look at the sun”.
When the Baily’s
Beads disappear and there is no longer any direct sunlight coming toward you,
you can look at the total eclipse safely.
