Eclipse 2018: What happens if you look at an eclipse? What happens during a solar eclipse? | Science | New

The solar eclipse of August 11 should be the most watched of 2018, according to TimeandDate.com, because the viewing opportunities around the world are the best

The partial eclipse should be visible from Northern Europe and the East, the United States and Northeast Asia during the day

The working group of the International Astronomical Union on solar eclipses said: "The partial solar eclipse of August 11, 2018 will be visible from the northernmost regions of the world

.The Norwegian Archipelago of Svalbard, site of visibility of a total solar eclipse in 2015, will have a partial eclipse of 45%.

"In the Scandinavian capitals of Oslo, Stockholm and Helsinki, the coverage will be five percent, four percent, and eight percent, respectively; with a nine percent coverage in St. Petersburg, Russia

What if you look at an eclipse?

A solar eclipse occurs when the moon moves between the sun and the Earth and blocks the sun's rays. the types of solar eclipses and partial eclipses occur when the moon partially obstructs the sun, casting its penumbra – outer shadow – on the Earth.

Watching the sun is extremely dangerous and can cause blindness or other forms of permanent eye damage. 19659002] NASA has already explained the dangers in an eye safety paper.

The document states: "When a person looks repeatedly or long in the sun without adequate protection for the eyes, this photochemical retinal damage may be accompanied by a thermal injury – the high level of visible and near-infrared radiation causes a warm-up (19659002) "This thermal injury or photocoagulation destroys rods and cones, creating a small, blind area.

5] "The danger to vision is important because photic retinal lesions occur without any pain (there are no retinal receptors) and visual effects do not occur for several hours after that the damage is done. 19659002] To safely observe a solar eclipse, use special eclipse glbades or make a pinhole projector with two maps

What happens during a solar eclipse? The sun and the Earth are in a three-line configuration known as syzygy.

During a partial eclipse, the three do not align symmetrically, meaning that the moon will only project its outer shadow onto the sun

the moon took a small sun sting.

During a total eclipse, the moon will cast its darkest part of its shadow, known as the umbra, on Earth.

The effect will make believe that the day has become night.
