A solar eclipse is one of those natural phenomena that attracts people all over the world – if you’re lucky enough to see it.
But what exactly is this sensational representation of light and shadow in the sky? Here’s what you need to know.
What is a solar eclipse?
eclipse is a beautiful celestial event that sees the Sun blocked by the Moon – casting a shadow over the Earth.
This partial or total blockage occurs when the Sun, Moon, and Earth are aligned.
When the Moon is between the Earth and the Sun in one new moon phase, it blocks light and casts shadows around the globe.
When the Sun’s rays are blocked, it allows everyone a chance to witness its fiery halo.
Total solar eclipse will happen on December 4, 2021and will reach the total at 2:44 a.m. EST (7:44 a.m. GMT).
There will be more penguins than people witness as it will only be visible in Antarctica.
But the partial eclipse will be visible from a few places in the Southern Hemisphere and The event is also available to watch live online.
Solar eclipse will be visible next year on October 25, 2022, from across Europe, northeast Africa, the Middle East and West Asia.
It will be a partial lunar eclipse – meaning only a small part of the Sun will be eclipsed when the Moon passes in front of it.
The Moon will partially obscure the Sun’s image to viewers on Earth, creating a spectacular effect for the skies.
This year June 10 event is a “ring of fire” solar eclipse, named for the red halo that appears around the Sun during alignment.
As the Moon envelops the center of the Sun, the edges emit a glowing circle creating an illuminated “ring of fire”.
What are the different types of eclipses?
There are four types of eclipses.
Total solar eclipse
This happens when the orbital planes align and the Moon appears to completely block light from the Sun.
The Sun is 400 times more massive than the Moon, but it is also 400 times farther from Earth.
These are the perfect proportions for the moon to completely obscure the sun, as long as the alignment on the Earth’s surface is correct.
When a total eclipse occurs – when the Sun is completely covered – the “halo” is revealed, which is the outer atmosphere of the Sun.
This happens when part of the Sun is always in view, creating “ghosting” or partial shadows.
A partial eclipse means that the center of the Moon’s shadow is off Earth, but it still creates a spectacular effect on the sky.
The amount of Sun eclipsed by the Moon depends on where the viewer of the event occurs.
This can range from a relatively small bite-sized piece appearing to the Sun in the shape of a slender crescent.
Annual solar eclipse
An annual eclipse is rare and is considered a variant of a partial eclipse.
An annular eclipse appears similar to a total solar eclipse in that the Moon appears to pass through the center of the Sun, creating a “false twilight”.
The event occurs when three objects that are not perfectly aligned with the Moon are much smaller than the Sun and the Sun is not completely covered.
As Space.com “During such a lunar eclipse, the antelope, a theoretical sequel to the umbra, hits the ground and anyone inside it can peer through either side of the umbra and see,” explains. an annular, or”ring of Fire“around the Moon.
“A good analogy is to place a coin on top of nickel, the coin is the Moon, the nickel is the Sun.”
They are also known as total annular (“AT”) lunar eclipses.
They occur when the moon’s distance approaches the limit of umbra to Earth.
An AT eclipse usually begins as an annular eclipse due to the umbra’s tip falling just short of contact with Earth; then it becomes whole, because the curvature of the planet rises and stops the darkness near the middle of the path, then it eventually returns to an annular shape towards the end of the path.
Of all eclipses, about 28% is total; 35% is partial; 32% are annular and only 5% are hybrid.
How often do eclipses happen?
Solar eclipses do not occur at every new moon.
The number of eclipses that occur varies, but is usually between two and five per year.
On average, a total lunar eclipse occurs somewhere on Earth about once every 18 months.
