Spectacular NASA Astronomy Pictures of the Week: Eagle Nebula, Dark Sunspots and more
sunniest spot on Earth
1/5 The mesmerizing Eagle Nebula (May 15) - This is a snapshot of M16, also known as the Eagle Nebula which spans about 20 light-years across. The nebula, discovered in 1745 by the Swiss astronomer Jean-Philippe Loys de Chéseaux, is located 7,000 light-years from Earth in the constellation Serpens, according to NASA. (NASA/Gianni Lacroce)

2/5 Sun’s Corona visible during solar eclipse (May 16) - Sun’s Corona was shot during a total solar eclipse. Temperatures in the Sun’s Corona can reach up to 2 million degrees and it is also the region where solar wind originates, according to NASA. While the hottest part of the Sun is its core, one of its most puzzling features is its Corona which extends more than 1 million kilometers from its surface. (NASA/Reinhold Wittich)

3/5 Sun’s Dark Sunspots (May 17) - Sunspots on the surface of the Sun in the active region AR 3297 were captured in this image. According to NASA, Sunspots are dark areas on the solar surface that contain strong magnetic fields that are constantly shifting and can form and dissipate over periods of days or weeks. They occur when strong magnetic fields emerge through the solar surface and allow the area to cool slightly. (NASA/Mark Johnston)

At the center of the Nebula is the Wolf Rayet star WR 134 named after French astronomers Charles Wolf and Georges Rayet. (NASA/Craig Stocks)

5/5 Snapshot of M63 Curly Spiral Galaxy (May 19) - The celestial object captured in this image is the M63 Curly Spiral Galaxy which is located about 30 million light-years away towards the constellation Canes Venatici. Also known as NGC 5055, this spiral galaxy spans almost 100,000 light-years. Spiral Galaxies like M63 are disks of stars, gas, and dust that have bright bulges in their centers made up primarily of older and dimmer stars. (NASA/Sophie Paulin/Jens Unger/Jakob Sahner)

Venus is a planet known for its un-Earthly temperatures. NASA says surface temperatures on Venus are about 900 degrees Fahrenheit (475 degrees Celsius). However, on planet Earth, there is a sun-soaked hellish place on our planet too and it is nestled in the heart of Chile and it is as sunny as the surface of Venus. But it is not the temperature that makes it so, it is the radiation hazard.

Scientists have recently disclosed that a desert in the vicinity of the Andes Mountains officially holds the title of the sunniest place on Earth. Situated in the Atacama Desert in northern Chile, the Chajnantor Plateau, standing tall at over 15,700 feet (4,800 meters) above sea level, boasts unparalleled levels of sunlight due to its remarkably cloudless conditions, according to a Washington Post report.

A Glimpse into Venus-like Radiance

The intensity of sunlight on the Chajnantor Plateau is so potent that being there is akin to experiencing the solar radiance found on the planet Venus. This astonishing revelation stems from an analysis conducted by researchers from the University of Santiago, who examined the region's climate and weather patterns.

Atacama Desert, Chile

The Atacama Desert, with its exceptionally arid and rainless conditions, experiences minimal cloud cover. Consequently, the Chajnantor Plain receives an abundance of sunlight.

During the summer months, average temperatures hover slightly above 39.2°F (4°C) due to the adjacent Pacific Ocean receiving frigid water currents from Antarctica. This mitigates the desert heat, making it a relatively chilly desert by day, despite its immense sunlight. However, this desert location is not an ideal spot for leisurely sunbathing.

An Extreme Solar Experience

In such extreme conditions, conventional sunscreens like Factor 20 prove inadequate to protect against sunburn. The sun's intensity at this location is unparalleled anywhere else on Earth, making it a unique and extraordinary scientific discovery.

Raul Cordero, a study author, remarked on the findings, stating, 'The radiation you would be receiving in summer if you were standing on Venus is comparable to what you experience at this particular location.'

To gather data, scientists utilized a five-year dataset collected at an observatory situated on the northwestern edge of the Chajnantor Plateau, approximately 17,700 feet (5,418 meters) above sea level. This data confirmed that the plateau not only possesses the highest level of horizontal shortwave radiation on the planet but also displays various other intriguing features.

One such phenomenon, known as 'forward scattering,' was observed among nearby clouds. This phenomenon often leads to intense bursts of sunlight, further enhancing the already sun-drenched landscape. In contrast to other places on Earth, where clouds tend to be dense enough to obstruct a significant portion of sunlight from reaching the ground, the Chajnantor Plain basks in a continuous stream of dazzling sunshine.

As this discovery sheds light on the extreme nature of the Chajnantor Plateau's climate, it stands as a testament to the astonishing diversity of Earth's landscapes and weather patterns. Though it might not be the ideal place for sunbathing, it certainly offers scientists a unique opportunity to study the solar phenomena that occur in such an exceptional environment.
