To honor the 50th anniversary of Earth Day and he 20th anniversary of NASA's Earth Observatory, the agency asked the public to pick our all-time best image on Earth. After five a five-round tournament and more than 56,000 votes, the readers chose Ocean Sand, Bahamas as their favorite.

We've posted 16 of the other top entrants. You can see the complete tournament results at Earth Observatory.


Ocean Sand, Bahamas (2001)

Though the above image may resemble a new age painting straight out of an art gallery in Venice Beach, California, it is in fact a satellite image of the sands and seaweed in the Bahamas.

The image was taken by the Enhanced Thematic Mapper plus (ETM+) instrument aboard the Landsat 7 satellite. Tides and ocean currents in the Bahamas sculpted the sand and seaweed beds into these multicolored, fluted patterns in much the same way that winds sculpted the vast sand dunes in the Sahara Desert.

Raikoke Erupts (2019)

via NASA

An unexpected series of blasts from a remote volcano in the Kuril Islands sent ash and volcanic gases streaming high over the North Pacific Ocean.

"What a spectacular image. It reminds me of the classic Sarychev Peak astronaut photograph of an eruption in the Kuriles from about ten years ago," said Simon Carn, a volcanologist at Michigan Tech. "The ring of white puffy clouds at the base of the column might be a sign of ambient air being drawn into the column and the condensation of water vapor. Or it could be a rising plume from interaction between magma and seawater because Raikoke is a small island and flows likely entered the water."

Where the Dunes End (2019)

via NASA

Mountains of sand, some as tall as 300 meters (1000 feet), reach from the floor of Africa's Namib Desert toward the sky. Driven by wind, these dunes march across the desert, bordered to the west by the Atlantic Ocean and in other directions by solid, rocky land.

The abrupt transition from sand to land is visible in these images, acquired on November 13, 2019, by the Operational Land Imager (OLI) on Landsat 8. They show the northern extent of the Namib Sand Sea—a field of sand dunes spanning more than 3 million hectares (more than 10,000 square miles) within the Namib-Naukluft Park, which was named a UNESCO World Heritage site in 2013. Sand appears red, painted by a layer of iron oxide.

Twin Blue Marbles (2007)

This view of Earth from space is a fusion of science and art, drawing on data from multiple satellite missions and the talents of NASA scientists and graphic artists. The twin images are a composite of multiple images taken between 1994 and 2004.

Fire in the Sky and on the Ground (2011)

via NASA

Astronauts on the International Space Station (ISS) used a digital camera to capture several hundred photographs of the aurora australis, or "southern lights," while passing over the Indian Ocean on September 17, 2011.

Retreat of the Columbia Glacier (2014)

via NASA

Scientists have long studied Alaska's fast-moving Columbia Glacier, a tidewater glacier that descends through the Chugach Mountains into Prince William Sound. Yet the river of ice continues to deliver new surprises.

Preliminary results show that both the West Branch and the East Branch (which feeds into the Main Branch) are now moving between 5 and 10 meters (16 and 33 feet) per day. That's slow for Columbia, but fast compared to other glaciers.

View of Earth from Saturn (2006)

via NASA

Seen from a billion kilometers away, through the ice and dust particles of Saturn's rings, Earth appears as a tiny, bright dot. The image is a composite (layered image) made from 165 images taken by the wide-angle camera on the Cassini spacecraft over nearly three hours on September 15, 2006.

The Dark Side and the Bright Side (2015)

via NASA

A NASA camera aboard the Deep Space Climate Observatory (DSCOVR) has captured a unique view of the Moon as it passed between the spacecraft and Earth. A series of test images shows the fully illuminated "dark side" of the Moon that is not visible from Earth.

The images were taken over the course of five hours on July 16, 2015.

A Voyager Far From Home (1977)

The image of a crescent-shaped Earth and Moon was captured on September 18, 1977, when Voyager was a mere 11.66 million kilometers (7.25 million miles) from Earth and directly above Mount Everest (on the night side of the planet at 25 degrees north latitude).

On September 5, 1977, NASA's Voyager 1 spacecraft lifted off from Cape Canaveral, Florida, aboard a Titan-Centaur rocket. Thirty-five years later, the planetary probe is now an interstellar traveler, having traveled farther from Earth than any manmade object in history.

Roiling Flows on Holuhraun Lava Field (2014)

via NASA

On September 6, 2014, the Operational Land Imager (OLI) on Landsat 8 captured this view of the ongoing eruption in Iceland.

Ice and the plume of steam and sulfur dioxide appear cyan and bright blue, while liquid water is navy blue. Bare or rocky ground around the Holuhraun lava field appears in shades of green or brown in this band combination. Fresh lava is bright orange and red.

Antarctica Melts Under Its Hottest Days on Record (2020)

via NASA

On February 6, 2020, weather stations recorded the hottest temperature on record for Antarctica. Thermometers at the Esperanza Base on the northern tip of the Antarctic Peninsula reached 18.3°C (64.9°F)—around the same temperature as Los Angeles that day. The warm spell caused widespread melting on nearby glaciers.

The warm temperatures arrived on February 5 and continued until February 13, 2020. The images above show melting on the ice cap of Eagle Island and were acquired by the Operational Land Imager (OLI) on Landsat 8 on February 4 and February 13, 2020.

Atafu Atoll, Tokelau (2009)

via NASA

At roughly eight kilometers wide, Atafu Atoll is the smallest of three atolls and one island (Nukunonu and Fakaofo Atolls to the southeast and Swains Island to the south are not shown) comprising the Tokelau Islands group located in the southern Pacific Ocean.

Making Waves in the Andaman Sea (2020)

via NASA

The Operational Land Imager (OLI) on Landsat 8 captured these images of the Andaman Sea on November 29, 2019. The reflection of the Sun on the ocean—sunglint—helps make the internal waves visible. The colors also have been slightly enhanced. The detailed swirls, fronts, and patterns are all quite real, but certain shades and tones in the data have been separated and filtered to make water features more visible.

Just Another Day on Aerosol Earth (2018)

During one day in August, tropical cyclones, dust storms, and fires spread tiny particles throughout the atmosphere.

The Electric Eye of Cyclone Bansi (2015)

Bansi formed in the southwestern Indian Ocean on January 11, 2015. By the time this photo was taken on the following day, Bansi had achieved tropical cyclone strength, with sustained maximum winds over 185 kilometers (115 miles) per hour. The cyclone would reach category 4 strength before becoming a weak extra-tropical system on January 19.

Awesome, Frightening Views of Hurricane Florence (2018)

Satellites and astronauts observed the potent storm as it headed for landfall in the southeastern United States.

Judy Vaughan has spent most of her life helping other women, first as the director of House of Ruth, a safe haven for homeless families in East Los Angeles, and later as the Project Coordinator for Women for Guatemala, a solidarity organization committed to raising awareness about human rights abuses.

But in 1996, she decided to take things a step further. A house became available in the mid-Wilshire area of Los Angeles and she was offered the opportunity to use it to help other women and children. So, in partnership with a group of 13 people who she knew from her years of activism, she decided to make it a transitional residence program for homeless women and their children. They called the program Alexandria House.

"I had learned from House of Ruth that families who are homeless are often isolated from the surrounding community," Judy says. "So we decided that as part of our mission, we would also be a neighborhood center and offer a number of resources and programs, including an after-school program and ESL classes."

She also decided that, unlike many other shelters in Los Angeles, she would accept mothers with their teenage boys.

"There are very few in Los Angeles [that do] due to what are considered liability issues," Judy explains. "Given the fact that there are (conservatively) 56,000 homeless people and only about 11,000 shelter beds on any one night, agencies can be selective on who they take."

Their Board of Directors had already determined that they should take families that would have difficulties finding a place. Some of these challenges include families with more than two children, immigrant families without legal documents, moms who are pregnant with other small children, families with a member who has a disability [and] families with service dogs.

"Being separated from your son or sons, especially in the early teen years, just adds to the stress that moms who are unhoused are already experiencing," Judy says.

"We were determined to offer women with teenage boys another choice."

Alexandria House also doesn't kick boys out when they turn 18. For example, Judy says they currently have a mom with two daughters (21 and 2) and a son who just turned 18. The family had struggled to find a shelter that would take them all together, and once they found Alexandria House, they worried the boy would be kicked out on his 18th birthday. But, says Judy, "we were not going to ask him to leave because of his age."

Homelessness is a big issue in Los Angeles. "[It] is considered the homeless capital of the United States," Judy says. "The numbers have not changed significantly since 1984 when I was working at the House of Ruth." The COVID-19 pandemic has only compounded the problem. According to Los Angeles Homeless Services Authority (LAHSA), over 66,000 people in the greater Los Angeles area were experiencing homelessness in 2020, representing a rise of 12.7% compared with the year before.

Each woman who comes to Alexandria House has her own unique story, but some common reasons for ending up homeless include fleeing from a domestic violence or human trafficking situation, aging out of foster care and having no place to go, being priced out of an apartment, losing a job, or experiencing a family emergency with no 'cushion' to pay the rent.

"Homelessness is not a definition; it is a situation that a person finds themselves in, and in fact, it can happen to almost anyone. There are many practices and policies that make it almost impossible to break out of poverty and move out of homelessness."

And that's why Alexandria House exists: to help them move out of it. How long that takes depends on the woman, but according to Judy, families stay an average of 10 months. During that time, the women meet with support staff to identify needs and goals and put a plan of action in place.

A number of services are provided, including free childcare, programs and mentoring for school-age children, free mental health counseling, financial literacy classes and a savings program. They have also started Step Up Sisterhood LA, an entrepreneurial program to support women's dreams of starting their own businesses. "We serve as a support system for as long as a family would like," Judy says, even after they have moved on.

And so far, the program is a resounding success.

92 percent of the 200 families who stayed at Alexandria House have found financial stability and permanent housing — not becoming homeless again.

Since founding Alexandria House 25 years ago, Judy has never lost sight of her mission to join with others and create a vision of a more just society and community. That is why she is one of Tory Burch's Empowered Women this year — and the donation she receives as a nominee will go to Alexandria House and will help grow the new Start-up Sisterhood LA program.

"Alexandria House is such an important part of my life," says Judy. "It has been amazing to watch the children grow up and the moms recreate their lives for themselves and for their families. I have witnessed resiliency, courage, and heroic acts of generosity."

It's one thing to see a little kid skateboarding. It's another to see a stereotype-defying little girl skateboarding. And it's entirely another to see Paige Tobin.

Paige is a 6-year-old skateboarding wonder from Australia. A recent video of her dropping into a 12-foot bowl on her has gone viral, both for the feat itself and for the style with which she does it. Decked out in a pink party dress, a leopard-print helmet, and rainbow socks, she looks nothing like you'd expect a skater dropping into a 12-foot bowl to look. And yet, here she is, blowing people's minds all over the place.

For those who may not fully appreciate the impressiveness of this feat, here's some perspective. My adrenaline junkie brother, who has been skateboarding since childhood and who races down rugged mountain faces on a bike for fun, shared this video and commented, "If I dropped in to a bowl twice as deep as my age it would be my first and last time doing so...this fearless kid has a bright future!"

It's scarier than it looks, and it looks pretty darn scary.

Paige doesn't always dress like a princess when she skates, not that it matters. Her talent and skill with the board are what gets people's attention. (The rainbow socks are kind of her signature, however.)

Her Instagram feed is filled with photos and videos of her skateboarding and surfing, and the body coordination she's gained at such a young age is truly something.

Here she was at three years old:

And here she is at age four:


So, if she dropped into a 6-foot bowl at age three and a 12-foot bowl at age six—is there such a thing as an 18-foot bowl for her to tackle when she's nine?

Paige clearly enjoys skating and has high ambitions in the skating world. "I want to go to the Olympics, and I want to be a pro skater," she told Power of Positivity when she was five. She already seems to be well on her way toward that goal.

How did she get so good? Well, Paige's mom gave her a skateboard when she wasn't even preschool age yet, and she loved it. Her mom got her lessons, and she's spent the past three years skating almost daily. She practices at local skate parks and competes in local competitions.

She also naturally has her fair share of spills, some of which you can see on her Instagram channel. Falling is part of the sport—you can't learn if you don't fall. Conquering the fear of falling is the key, and the thing that's hardest for most people to get over.

Perhaps Paige started too young to let fear override her desire to skate. Perhaps she's been taught to manage her fears, or maybe she's just naturally less afraid than other people. Or maybe there's something magical about the rainbow socks. Whatever it is, it's clear that this girl doesn't let fear get in the way of her doing what she wants to do. An admirable quality in anyone, but particularly striking to see in someone so young.

Way to go, Paige. Your perseverance and courage are inspiring, as is your unique fashion sense. Can't wait to see what you do next.

Since March of 2020, over 29 million Americans have been diagnosed with COVID-19, according to the CDC. Over 540,000 have died in the United States as this unprecedented pandemic has swept the globe. And yet, by the end of 2020, it looked like science was winning: vaccines had been developed.

In celebration of the power of science we spoke to three people: an individual, a medical provider, and a vaccine scientist about how vaccines have impacted them throughout their lives. Here are their answers:

When John Scully was born, America was in the midst of an epidemic: tens of thousands of children in the United States were falling ill with paralytic poliomyelitis — otherwise known as polio, a disease that attacks the central nervous system and often leaves its victims partially or fully paralyzed.

"As kids, we were all afraid of getting polio," he says, "because if you got polio, you could end up in the dreaded iron lung and we were all terrified of those." Iron lungs were respirators that enclosed most of a person's body; people with severe cases often would end up in these respirators as they fought for their lives.

John remembers going to see matinee showings of cowboy movies on Saturdays and, before the movie, shorts would run. "Usually they showed the news," he says, "but I just remember seeing this one clip warning us about polio and it just showed all these kids in iron lungs." If kids survived the iron lung, they'd often come back to school on crutches, in leg braces, or in wheelchairs.

"We all tried to be really careful in the summer — or, as we called it back then, 'polio season,''" John says. This was because every year around Memorial Day, major outbreaks would begin to emerge and they'd spike sometime around August. People weren't really sure how the disease spread at the time, but many believed it traveled through the water. There was no cure — and every child was susceptible to getting sick with it.

"We couldn't swim in hot weather," he remembers, "and the municipal outdoor pool would close down in August."

Then, in 1954 clinical trials began for Dr. Jonas Salk's vaccine against polio and within a year, his vaccine was announced safe. "I got that vaccine at school," John says. Within two years, U.S. polio cases had dropped 85-95 percent — even before a second vaccine was developed by Dr. Albert Sabin in the 1960s. "I remember how much better things got after the vaccines came out. They changed everything," John says.
