For the past 30 years, scientists around the world have been searching for planets beyond our solar system. Known as exoplanets, these worlds come in all shapes and sizes, each orbiting its own star. On September 17, 2025, NASA officially confirmed the existence of 6,000 exoplanets. Even more exciting, an additional 8,000 are just waiting to be verified!...

Climate change poses a serious threat to the Antarctic ecosystem. As temperatures continue to rise, sea ice is shrinking. This makes it harder for wildlife like seabirds, seals, and whales to find food, rest, or raise their young. Now, scientists may have found a surprising ally in their efforts to protect the continent — penguin poop....

Super Typhoon Ragasa swept across parts of Asia this past week, leaving behind widespread flooding and destruction. Ragasa began as a small weather system on September 17, 2025, and quickly grew into the year’s largest typhoon. By September 21, it had reached Category 5 strength, with top winds of 177 miles per hour (285 km/h)....

Since 2020, young Iberian orcas from a critically endangered subpopulation of fewer than 40 individuals have been ramming, and even sinking boats in the Atlantic Ocean. These incidents typically occur off the coasts of Spain, Portugal, and France during spring and summer. This is when the killer whales migrate to the area in search of food....

Earth’s atmosphere holds billions of gallons of water vapor. If captured, it could supply clean drinking water to over 2.2 billion people who do not have reliable access. Now, MIT scientists have built a device that can pull water from the air — even in some of the driest places on Earth....

Fat Bear Week is back! From September 23 through September 30, 2025, Alaska's Katmai National Park will invite fans worldwide to vote for the park's fattest brown bear. Now in its 11th year, the fun contest shines a spotlight on these remarkable animals and the Alaskan wilderness they call home....

Dolphin communication has always intrigued scientists. The intelligent mammals use a range of noises to work together and stay connected. Some sounds even act like names, helping dolphins recognize one another. Now, researchers at Google and Georgia Tech hope to understand dolphin speech — and maybe even talk to them — with the help of Artificial Intelligence (AI)....

A rare comet from another star system is speeding through our solar system, giving astronomers a unique chance to study an interstellar visitor up close. Named 3I/ATLAS, it is only the third such object ever confirmed. It joins Oumuamua, which appeared in 2017, and Borisov, detected in 2019....

A young Cooper's hawk in West Orange, New Jersey, has stunned scientists by using a pedestrian crosswalk as a hunting tool. This behavior marks a rare instance in which a bird of prey takes advantage of human infrastructure for survival....

In mid-June, over 200 people across the southeastern United States spotted a brilliant fireball streaking across the sky. It was a meteorite that soon slammed into a home in McDonough, Georgia. The space rock ripped through the roof, landing just 14 feet from the startled homeowner. The impact left a small crater on the floor....

Phoenix, Arizona, is one of the hottest cities in the United States. Summer temperatures there frequently exceed 110°F (43°C). To help residents cope with the extreme heat, city officials launched the ¡SOMBRA! Experiments in Shade project in early 2025....

On August 25, 2025, parts of Arizona were briefly engulfed by a massive dust storm during the evening rush hour, turning day into near darkness. Known as a haboob, these storms form when strong thunderstorm winds sweep across the desert, lifting loose soil into the sky....

A team of international researchers has captured the first-ever footage of an extremely rare Antarctic gonate squid swimming freely in its natural habitat. The species was previously known only from dead specimens caught in fishing nets or remains found in the stomachs of predators like whales and seals....

Barbie's Fashionistas line celebrates diversity and self-expression through a wide range of dolls. Launched by Mattel in 2009, the collection includes dolls with different body types, skin tones, and medical conditions. This includes dolls who are blind, have Down syndrome, and use a wheelchair or hearing aids. On July 8, 2025, the lineup welcomed a powerful new addition: a Barbie with Type 1 diabetes (T1D)....

Caterpillars are usually seen as harmless, plant-munching larvae. But a newly identified species discovered on the Hawaiian island of Oahu challenges that reputation. Measuring just 5 mm long, the "bone collector" caterpillar feeds on dead insects found in spider webs. It then repurposes the remains, wearing body parts like beetle shells and weevil heads as camouflage....

Each summer, the Northern Hemisphere night sky comes alive with one of the year's most dazzling celestial events: the Perseid meteor shower. Known for its bright, fast-moving meteors, the Perseids are a favorite of both casual stargazers and serious astronomers....

Over the Fourth of July holiday weekend, the Hill Country region in Central Texas experienced intense rainfall. This caused the Guadalupe River, which runs through much of the area, to surge over 26 feet (7.9 m) in about 45 minutes. The rapid rise triggered one of the worst flash floods in US history. The water swept through entire communities with little warning, engulfing land and washing away vehicles, buildings, and bridges. Thousands of residents lost their homes and businesses. As of July 25, 2025, 138 people have died — the 10th-highest toll on record for a US flash flood. Three are still missing....

Astronomers and skywatchers around the world are celebrating the release of the first images from the Vera C. Rubin Observatory. Unveiled on June 23, 2025, they mark a major milestone in the observatory's mission — to capture cosmic events as they unfold over the next ten years....

A robot built by undergraduate students from Indiana’s Purdue University has solved a Rubik’s Cube in an incredible 0.103 seconds. This is about twice as fast as an average human blink. Named "Purdubik’s Cube," it claimed a new Guinness World Record for the "Fastest robot to solve a rotating puzzle cube" on April 21, 2025. The previous record was held by a robot built in Japan by Mitsubishi Motors engineers in 2024. It completed the task in 0.305 seconds....

Chimpanzees are well known for their intelligence, especially in using tools to hunt and gather food. Now, new research on chimps at Gombe Stream National Park in Tanzania, Africa, suggests these clever primates are not just tool users — they may also be natural engineers....

Crows are remarkably smart animals, with thinking skills comparable to those of five- to seven-year-old children. They can solve puzzles, use tools, and even remember faces. Now, researchers at the University of Tübingen in Germany have found that these unassuming birds can also recognize different geometric shapes — a skill previously seen only in humans....

For centuries, the world beneath Antarctica’s thick ice shelves remained one of Earth’s greatest unknowns. No one knew what, if anything, lived there. That changed when a massive iceberg, roughly the size of Chicago, unexpectedly broke away. This rare event gave scientists a once-in-a-lifetime chance to explore a part of the planet that had never been seen before....

Spending time in space might sound thrilling, but it takes a serious toll on the human body. Weightlessness affects everything from muscles to blood flow. Hence, before astronauts head to the Moon or Mars, scientists must find ways to reduce the physical effects of long-term space travel....

In the summer of 2014, millions of people worldwide dumped buckets of ice water over their heads and challenged others to do the same. But this was not just for fun — they were taking on the Ice Bucket Challenge. The campaign, which went viral on social media, aimed to raise awareness and funds for ALS research, also known as Lou Gehrig’s disease. It raised an impressive $115 million for the ALS Association in just a few months....
