California's Yosemite National Park is known for its ancient giant sequoia trees and massive rock formations. These include El Capitan and Half Dome. However, from mid-to-late February, the park's main draw is the Horsetail Fall. Under the right conditions, this winter waterfall, takes on a fiery orange glow. This makes it look like lava flowing down El Capitan, giving it the name "firefall."...

After spending months spinning in the Antarctic waters, A23a, the world’s largest iceberg, is on the move again. This massive chunk of ice covers 1,418 square miles (3,673 sq. km). This is more than twice the size of the city of London. It weighs over a trillion tons and is about 1,312 feet (400 m) thick....

When a giant, dolphin-like animal washed ashore a beach in Otago, New Zealand, locals alerted the Department of Conservation (DOC). Upon arrival, the experts realized the 16-foot (5-meter) mammal was no dolphin. It was a spade-toothed whale, the rarest whale species known to science....

Since early January 2025, multiple large wildfires have erupted in and around Los Angeles (LA), California, tearing through dry vegetation and destroying entire neighborhoods. As of January 15, 2025, more than 12,000 homes, businesses, schools, and other structures have been destroyed. At least 25 people have died, and more than 100,000 have been forced to flee their homes. Many of these fires are still uncontained. Here is what we know so far....

A severe winter storm blanketed the Central and Eastern US with snow and ice. The intense system triggered a state of emergency across several states, from Kansas and Missouri to New Jersey. The Midwest was hit the hardest....

Kasanka National Park in Zambia, Africa, is home to an unlikely natural phenomenon — the world’s largest mammal migration. Each year, from October to December, millions of straw-colored fruit bats from across Africa converge on this evergreen swamp forest. These nocturnal mammals spend their nights feasting on wild fruits in the surrounding farmlands and their days resting in the forest. This cycle continues daily until January when the bats disperse and return to their respective habitats across the continent....

On November 1, 2024, Aron Fowler and his friends were at Ocean Beach, just south of Denmark in Western Australia, when they saw an emperor penguin walking toward them. This aquatic flightless bird had swum over 2,000 miles (3,218 km) from its usual habitat in the icy waters off the Antarctic coast. It was the first recorded sighting of an emperor penguin in Australia....

Full moons are always a stunning sight, but the one on November 15, 2024, promises to be even more spectacular. It will be the last of four consecutive supermoons, following August's Blue Moon, September's Harvest Moon, and October's Hunter Moon. After this, the next supermoon will not occur until October 7, 2025....

The sea robin is a bottom-dwelling fish uniquely adapted to life on the ocean floor. These fascinating creatures have frog-like eyes, wing-like fins, and six crab-like legs. Scientists have now discovered that at least one species, the northern sea robin, uses these legs both for walking and for "tasting" the sea floor for buried prey....

Every fall, Americans buy tens of millions of decorative pumpkins. Some are carved into spooky jack-o'-lanterns, while others are used simply for display. Unfortunately, the interest in these colorful gourds fades soon after Halloween. Experts estimate that over one billion pounds of pumpkins — more than 80 percent of the 1.3 billion pounds purchased annually — end up in landfills....

In mid-September 2023, a mysterious event set off earthquake sensors worldwide. However, unlike typical earthquake readings, which are quick and sharp, this data showed a slow, constant wave. What surprised scientists even more was that the rumbling continued for nine consecutive days before finally subsiding....

Octopuses are among the smartest marine animals. These intelligent cephalopods are known for using coconut shells as mobile homes and armor and changing colors on demand to evade predators. A new study by researchers at Germany's Max Planck Institute of Animal Behavior found that octopuses can also be strong leaders. They take charge of hunting packs and even discipline those who try to cheat....

In the wild, animals frequently use deceptive tactics to survive. For instance, some wasps turn spiders into "zombie" slaves to build intricate nests. Similarly, mouse-eared bats mimic hornet buzzes to avoid being preyed upon by owls. Now, a new study reveals that a crafty orb-weaver spider species has found a way to manipulate the mating signals of male fireflies to catch more prey....

Food waste is a major contributor to greenhouse gas emissions. As food decomposes in landfills, it releases methane and carbon dioxide. These potent gases accelerate global warming and climate change. Experts estimate that nearly a third of the world's food, about 1.3 billion tons, is wasted annually. This waste generates a staggering 3.3 billion tons of greenhouse gases each year. It accounts for 8 to 10 percent of global emissions....

Earthworms are well-known for their ability to enrich and improve soil. Yet, their precise impact on plant growth had remained a mystery. Now, two groundbreaking studies have found that these creepy crawlers not only boost crop yields but also protect plants from harmful microplastics....

On September 26, 2024, at 11:10 pm EST, Hurricane Helene made landfall near Perry, Florida, as a dangerous Category 4 storm. With sustained winds of over 140 miles per hour (225 km/h), it was the most powerful hurricane to hit the region since record-keeping began in 1851. After causing widespread damage, Helene continued on to several states, including Georgia, North Carolina, South Carolina, Virginia, and Tennessee....

A herd of 100 life-sized elephant sculptures have begun their trek across the United States. The "Great Elephant Migration" aims to promote harmony between humans and animals. The project is spearheaded by Ruth Ganesh. She is a trustee of Elephant Family USA and cofounder of The Coexistence Collective, a community of 200 indigenous artists in Southern India....

Since 2020, juvenile orcas have been intentionally colliding with boats off the coasts of Spain, Portugal, France, and Morocco. The most recent incident occurred off Spain’s northwest coast on August 25, 2024. A pod of killer whales damaged the rudder of a sailboat named the Amidala, leaving its two passengers stranded. While this boat remained afloat, the orcas' attacks have caused at least seven vessels to sink in the past four years....

Carbon dioxide (CO2), released by burning fossil fuels like oil and coal, is a large contributor to global warming. Switching to renewable energy sources like solar panels and wind turbines can help reduce the harmful emissions. However, phasing out fossil fuels entirely will take time. Meanwhile, companies like Climeworks are developing innovative solutions to reduce atmospheric CO2 levels. On May 8, 2024, the Switzerland-based startup turned on Mammoth, the world's largest direct air capture (DAC) plant....

The Big Basin Redwood State Park in Santa Cruz, California, is home to some of the tallest and oldest redwood trees on Earth. The towering trees reach heights of over 300 feet (91 m) and have an incredibly thick bark. This natural armor usually protects their upper branches and needles from wildfire damage. However, the CZU Lightning Complex Fire that burned 97 percent of the park in August 2020 was so intense that it even scorched these ancient giants....
