Heavenly observers are looking for fun this week, while the Moon passes between Earth and the Sun, resulting in a complete solar eclipse.
It will be the first full solar eclipse since August 2017 when millions of people in the United States could witness a spectacular first-hand phenomenon.
However, this complete solar eclipse will not be visible anywhere in the northern hemisphere.
If you are not on a ship in the middle of the South Pacific, the best places to see are Chile and Argentina.
For this reason, it is called the total solar eclipse of 2019.
Here's what you need to know.
What is the total solar eclipse?
The solar eclipse occurs when the moon passes between Earth and the Sun, hiding the sun from the sight.
When it seems that the moon of a disk completely covers the sun's disk in the sky, it is known as the complete solar eclipse. If the sun part is still visible, it is known as a partial solar eclipse.
The solar eclipses occur because the moon circulates around the Earth on an average of 239,000 miles – which is at a fair distance to appear in the same magnitude as the much larger sun, which is 93 million miles away.
This incredible coincidence means that when a moon passes in front of the sun, it seems to cover it perfectly.
How does it look like?
Occasional observers and professional astronomers agree that Total Solar Eclipse is one of the deepest and most spectacular in the world.
"Only as a whole can be seen glimpses like the pink galaxy of a nuclear blast with naked eyes from the sun's extremity," Robotics Telescope Service Slooh said.
"Only then brighter stars and planets emerge from the black sky, while the sun's ultra-hot crown reveals far above the sky, and its plump shields are channeled along the giant lines of the Sun's magnetic field.
"The same shape of the solar corona appears to be different and distinctive for any eclipse, and largely depends on the phase of the sunshine cycle."
When is South America a complete eclipse of 2019?
A rare heavenly event will be held on Tuesday, July 2, shortly after 16:30 local time (20:30 BST).
The moon will first appear in contact with the sun above the Pacific at 12:55 am EDT (17:55 BST). This will be the beginning of a partial phase of eclipse.
Totality will be first seen on Oeno Island, British territory in South Pacific, at 10:24 local time (17:24 BST).
The first place in South America to see the total will be near La Serena in Chile, where the total eclipse will be visible at 16:39 local time (20:39 BST).
Where can I watch the sunset?
The complete solar eclipse is visible from small parts of Chile and Argentina just before sunset.
Some regions in the Pacific Ocean and South America, including locations in Ecuador, Brazil, Uruguay, and Paraguay, will also see a partial sunburn, if weather permitting.
"The South American ambush in 2019 is not easy to capture," said Paul Cox, chief astronomer of the Slooh Observatory.
"Unlike the 2017 eclipse, the road of totality (90-mile wide Moonshade skewed path) makes landfall across the narrow part of Chile and Argentina.
"After running over Pacific Ocean at more than 6,000km / h, until the Moon's shadow reaches the west coast of Chile, the Sun will be low until the horizon, while the phases of the partial eclipses occur just as the Sun sets."
If you are not happy enough to be on the road to totality, you will be able to watch live from numerous observation spots in Chile and Argentina.
When is the next solar eclipse in the UK?
The next real good eclipse visible from the United Kingdom will be August 12, 2026, when Britain will experience a very large partial erosion, from 96% in Cornwall to 91% in Aberdeen.
The next complete ecstasy visible in the UK is not until September 23, 2090.
