Mount Everest, Earth's highest peak, is growing faster than expected. Recent GPS measurements indicate it is adding up to 2 millimeters annually. This is nearly twice the previously estimated rate. This growth is mainly due to the collision of the Indian and Eurasian tectonic plates over the past 50 million years. However, a new study by the China University of Geosciences suggests that a river capture event may also be helping the growth of the 29,032-foot (8,849-meter) mountain....

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....

A team of scientists looking for dinosaur fossils in 2020 made a rare discovery. They found a well-preserved tadpole dating back 161 million years to the middle Jurassic period. This discovery breaks the record for the oldest known tadpole fossil by about 20 million years!...

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....

Since 1967, the annual Consumer Electronics Show (CES) has wowed Americans with innovative — and sometimes wacky — gadgets. This year’s event, held in Las Vegas, Nevada, from January 7 to 10, 2025, was no exception. Here are some standout products that caught our attention....

NASA is preparing to launch one of its most exciting missions yet. In 2028, the Dragonfly lander will embark on a journey to Titan, Saturn's largest moon. The primary objective of this $3.35 billion mission is to find evidence of early life....

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....

As days grow shorter and temperatures drop, it might seem like winter has already arrived. However, the astronomical start of winter in the Northern Hemisphere will not occur until December 21, 2024. This date, known as the winter solstice, marks the shortest day and longest night of the year. Meanwhile, residents of the Southern Hemisphere will celebrate the summer solstice on the same day. They will enjoy the longest day and shortest night of 2024....

A rocket built by students at the University of Southern California (USC) Rocket Propulsion Lab (RPL) has shattered a 20-year record. Aftershock II, launched from Nevada's Black Rock Desert on October 20, 2024, reached an altitude of 470,000 feet (143.3 km). This was 90,000 feet (27.4 km) higher than the previous amateur rocket altitude record of 380,000 feet (115.8 km). It was set by the Civilian Space eXploration Team’s GoFast rocket in 2004....

With Christmas just around the corner, your neighborhood is likely aglow with beautiful lights. But those displays pale in comparison to nature's dazzling light show — the Geminids. Nicknamed the "900-pound gorilla of meteor showers" by NASA, the Geminids outshine others with dust streams that are 5 to 500 times more massive. The "shooting stars" are also easier to spot because they travel through the skies at about 22 miles (35 km) per second. This is about half the speed of the Perseid meteors, which zip by at about 37 miles (60 km) per second every year in August....

LignoSat, the world’s first satellite made mostly from wood, reached the International Space Station (ISS) aboard a SpaceX cargo capsule on November 5, 2024. The palm-sized satellite, named after the Latin word for “wood," will be launched from the ISS into Earth’s orbit later this month. Its mission is to determine if wood can withstand the harsh conditions of space. If successful, LignoSat could pave the way for more environmentally friendly spacecraft designs....

Over the years, astronomers have managed to capture a few images of stars in galaxies beyond Earth. However, these images have always appeared as mere points of light, even when seen through powerful telescopes. Now, thanks to the Very Large Telescope (VLT), scientists have captured the first close-up image of a massive star located a staggering 160,000 light-years from Earth....

Drones have come a long way since the first model that barely lifted two feet (60 cm) off the ground was unveiled in 1907. Modern quadcopters can soar to high altitudes and perform a wide range of tasks. However, their capabilities are often curbed by limited battery life....

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 next time you are upset about short winter days, think about Utqiaġvik (formerly Barrow), Alaska. The residents of America's northernmost town will experience their final sunset this year on November 19, 2024. They will not see the Sun again until January 23, 2025. For those wondering, that is 65 straight days, or 1,560 hours, of darkness!...

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....

NASA’s latest mission takes the search for life to new frontiers — this time to Jupiter’s fourth largest moon, Europa. On October 14, 2024, the Europa Clipper spacecraft launched from the Kennedy Space Center in Florida to uncover the secrets of this distant moon....

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....

Planetary rings are a natural feature of the larger outer planets like Jupiter and Neptune, but none are as spectacular as Saturn's. However, in March and November 2025, these majestic rings will not be visible to observers on Earth. Fortunately, this rare event is only an optical illusion. It is caused by the orientation of Saturn's thin rings and the planet's tilt relative to Earth. The last time this occurred was in 2009....

SpaceX has achieved yet another groundbreaking milestone. On October 13, 2024, the aerospace company successfully flew the 233-foot (71 m) Starship rocket booster back to its launch site and caught it mid-air with two mechanical arms. Previously, SpaceX boosters landed on a floating platform or landing pad and required transportation back to the launch site....

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....

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....
