Located in California's Sierra Nevada mountains, Yosemite National Park is famous for its giant, ancient sequoia trees and impressive rock formations, like El Capitan and Half Dome. However, from mid-to-late February each year, the pristine preserve's main attraction is Horsetail Fall — a temporary waterfall that flows over the eastern edge of El Capitan every winter. During the brief two-week-period, the 1,500-foot-tall waterfall frequently transforms into a spectacular natural Firefall....

Before astronauts land on Mars, scientists must know everything they can about its inhospitable landscape. While the various exploration vehicles dispatched over the years are providing researchers with invaluable data, the bulky machines are constrained to exploring flat surfaces close to their respective landing sites....

This week's severe winter storm, which dumped record amounts of snow in the Mid-Atlantic and the Northeast, had most residents scrambling for the safety and warmth of their homes.

Those hoping for some respite from the powerful nor'easter that is currently pummeling the US East Coast and Mid-Atlantic with heavy snow and near-blizzard conditions are in for a disappointment. On February 2, 2021, aka Groundhog Day, legendary woodchuck Punxsutawney Phil observed his shadow. This — according to folklore — means that the frosty weather will remain with us for an additional six weeks....

With a series of storms unleashing their fury across the United States this week — all the way from California to New York — many Americans are experiencing the full wrath of the winter season. Freezing as the temperatures may seem, they are balmy compared to those in Yakutsk, the capital of Yakutia, or the Sakha Republic, in Russia. The residents of this remote Siberian city have been enduring average temperatures of below -30°F (-34°C) since December 8, 2020, with the mercury dipping as low as -59° F (-50.6 °C) on January 19, 2021....

Mars is famous for its orangish-red hue caused by the iron oxide in its soil. However, the Red Planet's surface, which has been drastically altered by volcanoes, impact craters, crustal movement, and atmospheric conditions such as dust storms, is also home to a wide range of fascinating topographical features. High among the list is Valles Marineris — the Solar System's longest and deepest-known canyon....

If you think all penguins look alike, you are not the only one. A hilarious video, captured by Andrea Barlow, director of the Falkland Islands Museum and National Trust, reveals that the aquatic, flightless birds sometimes also have a hard time distinguishing between one another....

With over 4.1 billion people, or around 55 percent of the world's population, living in urban areas, cities and towns worldwide are getting increasingly congested. In addition to spending an excessive number of hours stuck in traffic, residents are also exposed to high air pollution levels caused by transportation emissions. Now, Saudi Arabia hopes to revolutionize urban living with "The Line" — a futuristic city designed around nature, without cars and roads!...

When paleontologists discover a new dinosaur species, they usually marvel at the ancient creature's size or speed.

In late November 2020, German divers, commissioned by the World Wildlife Foundation to extract abandoned fishing nets from the Baltic seafloor, stumbled upon what appeared to be a pristinely-preserved ancient typewriter. However, a closer look at the rusted, algae-covered contraption revealed that the artifact was far from a typewriter. It was a rare Enigma machine, used by German armed forces to send messages securely during the Second World War....

After erupting almost continuously for over three decades — from 1983 to 2018 — Hawaii's Kilauea volcano finally seemed to lose steam, producing no lava for nearly two years. The slumber ended on the night of December 20, 2020, when the active volcano began spewing out dramatic lava fountains and giant puffs of gas and steam from a fissure in the northwest wall of the Halemaʻumaʻu crater....

In the past, the heartwarming footage has shown the airline's employees surprising a few, unsuspecting families with extravagant gifts, ranging from iPods to vacations to diamond rings.

China’s Chang’e 5 spacecraft, tasked with bringing lunar rock samples to Earth, successfully landed on the Moon on December 1st, 2020. The 18,100-pound (8,200 kg) spacecraft, launched from China’s Wenchang Spacecraft Launch Site on November 23, 2020, entered the satellite's orbit on November 28th, 2020. Soon after, it deployed its lander and ascender modules to the Mons Rümker, an isolated volcanic formation on the Moon's near side....

Mention goldfish, and the image that comes to mind is that of small, colorful creatures swimming in circles in fish bowls or home aquariums. However, the one recently discovered by biologists conducting a fish survey at a South Carolina lake was no ordinary goldfish - it was a 9-pound, 15-inch-long behemoth!...

Over the years, the caretakers at the Southern Plains Wildlife Rehabilitation Center (SPWRC) in Lubbock, Texas, have sheltered hundreds of species of orphaned and injured animals, ranging from birds to reptiles. However, the hairless baby opossum, dropped off at the center in mid-October by a concerned resident, was unlike any animal they had encountered before....

With much of our world automated, many experts believe that coding should be a core part of modern education. Yet, only 20 US states offer high school students access to computer science courses, and just 8 of those make the subject accessible to kids in lower grades. However, thanks to Seattle-based Code.org's Hour of Code Challenge, learners of all ages and backgrounds can now get exposure to this all-important subject....

While Black Friday and Cyber Monday are all about finding the best deals on holiday gifts for yourself and family members, Giving Tuesday serves a more altruistic purpose. Observed annually on the Tuesday after Thanksgiving, it encourages people to help those in need by making financial donations or doing good in their local community. The “Global Day of Giving” was started in 2012 by New York City nonprofit 92nd Street Y and the United Nations Foundation....

Extreme athletes have been using wingsuits — unique jumpsuits with fabric stitched between the arms and body and between the legs — to fly untethered for many years. However, while the "birdman" or "squirrel" suits allow daredevils to soar in the skies, the pull of gravity makes it impossible to accelerate or fly higher. To push past the limitations, Austrian stuntman Peter Salzmann teamed up with German car manufacturer BMW. The result is an electrified wingsuit, which allows flyers to zoom to higher altitudes at speeds of up to 186 miles per hour!...

Gorillas, which can weigh as much as 400 pounds, are the largest of the great apes, a family of primates that include bonobos, chimpanzees, and orangutans. Despite their size, the intelligent mammals are known to be surprisingly gentle. Evidence of the animals' kind nature was recently caught on tape at a zoo in New South Wales, Australia....

While giant panda cubs are always popular, 22-year-old Mei Xiang's latest offspring, born at the Smithsonian's National Zoo on August 21, 2020, is particularly so. The daily live-stream of the adorable male cub, whose birth brought much-needed cheer during the COVID-19 pandemic, has garnered over a million virtual visitors. Hence, it is only fitting that zoo officials are asking fans to help name the precious 12-week-old....

Stars that get too close to black holes usually end up getting sucked in by the strong gravitational forces of the dense space objects, from which no light can escape. Now, for the first time, researchers have been able to observe the cosmic phenomenon — nicknamed "spaghettification" because it pulls apart a star into thin "spaghetti-like" strands — in real-time....

The residents of Florida, which is home to over one million alligators, are no strangers to the apex predators. The massive animals are frequently encountered in swimming pools, ditches, and garages. In 2019, Palm Coast resident Donna Heiss even saw a 7-foot gator peeking through her window! However, the giant reptile recently spotted in Naples, Florida, impressed even the most jaded Floridians....

Soft robots, which can move around the ocean without harming sea life, are ideal for underwater exploration. However, they are rarely deployed because they are extremely slow and have a hard time maneuvering through the water. But that may change soon thanks to an innovative, self-propelling soft robot created by researchers at the University of California, San Diego....
