How Australia’s Lake Hillier gets its pink color

Lake Hillier in the Recherche Archipelago of Western Australia off the coast of Cape Arid National Park is known for its pink color.

Scientists postulate that the lake’s solid bubblegum pink color results from the intermixing of Halobacteria and a salt-tolerant algae species called Dunaliella Salina.

Halobacteria produce red pigments mixed with salt-tolerant Dunaliella Salina, creating a stunning strawberry milkshake color.

The chemical reactions between the salt and the microorganisms make the lake ten times saltier than the ocean nearby.

There are 29 other pink lakes in the world. But unlike other pink lakes that morph into different colors, Lake Hillier retains its pink hue all year round. It’s also safe to swim in.

The Wave in Vermilion Cliffs Wilderness, Arizona

The Wave is a sandstone rock located in Vermilion Cliffs National Monument on the Arizona and Utah borders.

The swirling formation combines water and wind eroded sandstone dunes calcified vertically and horizontally and fossilized over 190 million years.

Only 20 people are permitted to visit the natural wonder daily, which can only be reached by foot.

Two ash-covered bodies from Vesuvius eruption uncovered at Pompeii

Archaeologists uncovered the body of a wealthy 40-year old man and his young slave in Pompeii, 2,000 years after the eruption of Mount Vesuvius. 

Excavations at the suburban villa Civita Giuliana, a suburb outside Pompeii, discovered the bodies covered in a bed of 6.5-foot ash.  

Researchers believe that the two men survived the initial eruption from Mount Vesuvius, only to succumb to a massive and more destructive cloud of scorching ash while seeking shelter in a cryptoporticus

The skeletal remains follow last year’s discovery of another Ancient Roman man crushed by a flying rock during Mount Vesuvius’s eruption in 79 A.D.

There are different types of tears

Did you know that we shed different types of tears based on our emotions?

Each tear type is composed of unique chemicals — mainly salt, water, and lysozyme — that give them their variable structure.

There are different types of tears

Emotional tears contain a natural painkiller

According to scientist Claire Phillips, tears of grief contain the neurotransmitter leucine enkephalin which helps relieve the body in times of stress. In such a way, our tear ducts can act as a natural painkiller.

There’s a biological and evolutionary reason we feel better shedding tears after experiencing a traumatic event.

Photographer captures rare Devil Horns solar eclipse over the Persian Gulf

On December 26, 2019, amateur photographer Elias Chasiotis captured an incredible ‘red devil horns’ sunrise over the Persian Gulf during a rare solar eclipse. 

The Athens-based photographer was vacationing in the coastal city of Al Wakrah in Qatar just before the new year when he snapped the rare spectacle of the moon blocking the sun. The sun appears to rise in two pieces amid the cloudiness. 

“Astronomy has attracted me since I was a kid,” Chasiotis said in an interview with Bored Panda. “I’ve been an amateur astrophotographer for the last 15 years as well. I took these photos in the coastal city of Al Wakrah, Qatar, on the morning of December 26, 2019, when an annular eclipse was in progress.”

“I was worried that nothing would come out of the eclipse. However, when the sun finally began to rise, it looked like two separate pieces, some sort of red horns piercing the sea. It soon took the form of a crescent, with the so-called ‘Etruscan vase’ inferior mirage effect visible. Due to its shape, the phenomenon was nicknamed the ‘evil sunrise.’”

Interestingly, images of the red crescent sunrise emerged a few days before the assassination of Iranian General Qasem Soleimani. Make of that what you will.

UFO, lampshade? An amazing lenticular cloud hovers over Japan’s Mount Fuji

They look like flying saucers or marshmallows.

These UFO-looking lens-shaped clouds called lenticular clouds often develop near the peaks of mountains, as in the case of Mount Fuji in Japan.

Lenticular clouds form when strong winds force air up and over a topographic barrier such as a mountain. Once the rising air hits the obstructive peak, an “eddie”, and then mixes with the upper-wind, the air deflects the mountain wind downward to create the lampshade looking clouds.

Here’s a collection of lenticular clouds forming in different settings — over buildings, volcanoes, and grassy fields. You love to see it!

Iceland’s Vestrahorn mountain and its ‘horny’ peaks

Vestrahorn mountain in south-east Iceland is one to behold.

Nicknamed “Batman Mountain” for its awe-inspiring beauty, the 1490 foot mountain looks down at the flat black sand of Stokksnes Beach below.

Known for its spiky ‘horny’ peaks that resemble the horns on a bull, Vestrahorn is composed of both gabbro and granophyre rocks.

In order to access the photogenic landscape of the mountain beach, you’ll need to make a small payment to the landowner first. The mountain is situated on private property.

By the looks of it, the experience is worth every penny — especially if you get to see the mountain on a clear night with the Northern Lights.

The Dragon’s Eye Stone Mine in the UK

What looks like a scene out of Indiana Jones or a J.R.R. Tolkien novel, the Dragon’s eye stone mine was discovered at the Hall of Giants stone mine in Lancashire UK.

The underground adventurers who discovered the mine in Northern England took the picture using a fisheye lens — the surface is actually flat rather than curved.

The dragon’s eye formed as a result of a collapsed mine roof that exposed different color sediments.

We can’t be the only ones just waiting for the stone to blink.

NASA and ESA capture closest images of the sun ever taken

NASA and the European Space Agency (ESA) have snapped the closest pictures ever taken of the sun.

The images, taken nearly 48 million miles away from the sun’s surface by the Solar Orbiter probe (launched February 9), reveal countless tiny flares which scientists have called “campfires.”

Scientists hope that these never-before seen exterior shots will help explain why the sun’s solar corona or atmosphere (over 1 million °C) is 300x hotter than its actual surface.

Earlier this year, the National Solar Observatory (NSO) brought us the sharpest movie of the sun we’ve seen which revealed each plasma cell the size of Texas.

The people’s pollution?

Human absence is having an environmental impact on the city.

Dolphins are purportedly swimming through the city’s canals and the swans have returned.

One can see also little fish swimming in clear waters, also an unexpected side effect of the pandemic.
