On November 7, 2023, the European Space Agency (ESA) released the first images from its deep space telescope, Euclid. The stunning full-color photos offer the clearest views of our cosmos yet. They are part of the telescope's six-year mission to create an extensive 3D map of the Universe around us. Scientists hope it will help solve the mysteries of dark energy and dark matter that make up 95 percent of our Universe....

Australian researchers recently unveiled an exceptionally well-preserved fossil of an ancient spider. The arachnid roamed the continent between 16 million and 11 million years ago. Megamonodontium mccluskyi was unearthed at the McGraths Flat in New South Wales. Once covered with lush rainforests, the site has an abundance of insect and plant fossils that existed during the Miocene era. Many are new to science....

With about 100,000 new cases diagnosed annually, skin cancer is the most common type of cancer in the US. It is also expensive to treat. The CDC estimates that over $8 billion is spent annually to fight the disease. Now, scientists may have some help from 14-year-old Heman Bekele. The ninth-grader from Annandale, Virginia, has created a cheap bar of soap that could potentially help fight skin cancer. His invention won him the title of "America's Top Young Scientist" at the 3M Young Scientist Challenge on October 10, 2023....

Glue manufacturers must find a balance between two things when making the sticky substance — how strong it holds and how easily it can be pulled apart. That's because boosting one attribute usually weakens the other. As a result, the end product is either not sticky enough or extremely strong. The latter makes it hard to undo to adjust for mistakes or when the product is no longer useful. Now, scientists in Japan have created an intriguing, reusable glue that can instantly be stuck on and off....

Fall stargazing is about to get even more exciting. On October 14, 2023, the Moon will partially block the Sun, turning it into a stunning "ring of fire." The annular — Latin for ring-shaped — solar eclipse will be visible within a roughly 125-mile-wide (201 km) path from Oregon to Texas. The last time the US witnessed an annular eclipse was on May 20, 2012. The next time will not be until July 2084!...

Full Moons are always a stunning sight. However, the "Harvest Moon" that will light up the skies on September 29, 2023, promises to be even more spectacular given that it is a supermoon. More importantly, it will be this year's fourth and final supermoon!...

We have all experienced the strong link between smell and memory. A whiff of chlorine probably reminds you of summer pool parties, while the scent of flowers may bring back memories of your grandma's garden. Now, researchers from the University of California, Irvine (UCI) have found that breathing in pleasant aromas could even help improve memory and learning....

Just days after landing a spacecraft on the Moon's South Pole, India turned its attention to the Sun. On September 2, 2023, the Indian Space Research Organization (ISRO) successfully launched the Aditya-L1 spacecraft to study the fiery star....

Scientists at Aix-Marseille University in France believe they have identified the world's first-known "boomerang meteorite." They think the Earth rock got tossed into space, where it spent thousands of years before returning home....

In a remarkable feat, India successfully landed its Chandrayaan-3 spacecraft on the Moon's surface on August 23, 2023. It is only the fourth nation in the world — after the former Soviet Union, the US, and China — to accomplish this achievement. Even more impressive, India is the only country to land a spacecraft on the southern lunar pole....

On June 25, 2023, four Americans began their 378-day stay on a simulated version of Mars at the Johnson Space Center in Houston, Texas. The mission, dubbed CHAPEA, or Crew Health and Performance Exploration Analog, is the first of three experiments planned by NASA. They are designed to test the mental and social challenges astronauts will face when they get to Mars....

Like most fish, sharks are largely ectothermic, or cold-blooded. This means their body temperature depends on the water around them. To avoid freezing, most shark species remain close to the ocean's surface, where the water temperatures are warmer. However, scalloped hammerheads have long been known to dive thousands of feet into the ocean's cold depths in search of prey. Researchers from the University of Hawaii at Mānoa have now uncovered the shark's long-kept secret. The smart fish shut their gills and "hold their breath" to stay warm....

It is no secret that play-based learning improves the cognitive, physical, social, and emotional well-being of children. Researchers now believe that certain board games, like Chutes and Ladders and Monopoly, can also help enhance their math skills....

When a large star dies, it explodes into a brilliant burst of light that temporarily illuminates the night skies. The phenomenon, known as a supernova, often lasts for weeks. However, it is usually only visible to scientists with access to powerful telescopes. But the SN 2023ixf — one of the largest and brightest supernovas in over a decade — can be seen by all!...

Visitors to Utah's Cache County are being treated to a stunning sight — mountain ranges covered with pink and red snow. The "watermelon snow" is not the work of an ambitious artist. Instead, it is a natural phenomenon caused by Chlamydomonas nivalis algae....

On Wednesday, June 21, 2023, Northern Hemisphere residents will celebrate the astronomical start of summer. Also known as the June solstice, it is the day when the North Pole is most inclined toward the Sun. This means those in the Northern Hemisphere will enjoy the longest day of 2023. Conversely, residents of the Southern Hemisphere will mark the first day of winter with the shortest day of the year....

Exposure to microgravity can wreak havoc on the human body. Hence, before astronauts can embark on the long trip to the Moon or Mars, scientists need to find ways to mitigate the physical impacts of space travel....

Scientists have long theorized that older stars swell up as they age and devour nearby planets. However, the assumption has been derived from observations made before and after the event. Now, for the first time, astronomers have caught a star in the act of engulfing a planet. The star, known as ZTF SLRN-2020, resides approximately 12,000 light-years away in our galaxy near the Aquila constellation....

When Suzy Kop entered her father's bedroom on May 8, 2023, she was stunned to find a grapefruit-sized rock next to a big dent on the wooden floor. Upon further investigation, the New Jersey resident saw two holes in the ceiling. It appeared that the stone had struck the floor with such great force that it rebounded and punched a second hole before landing back....

To the untrained eye, the spotted lanternfly (Lycorma delicatula) may look like a beautiful butterfly. The insect's front wings are light brown with black spots, while its hind wings have contrasting patches of red and black with a white band in between. However, the spotted lanternfly is a pest that feasts on and damages crops. It poses a serious threat to farmers across America....

On April 25, 2023, Mattel unveiled the latest addition to their Barbie Fashionistas collection — a doll with Down syndrome. The world's largest toy maker hopes it will allow more children to connect with Barbie....

In early March 2023, Murphy, a bald eagle at the World Bird Sanctuary in Valley Park, Missouri, began to spend his entire day sitting on a makeshift nest inside his aviary. The behavior was not unusual in itself. Male bald eagles always help females during the incubation process. However, in this case, the 31-year-old bird was trying to hatch a rock!...

Black holes have incredibly powerful gravitational pulls. They usually gobble up everything around them. However, for the first time ever, scientists have found a black hole that is creating millions of stars as it zips through space....

Over the years, scientists have used 3D printers for various products. They include electronic devices, jewelry and even artificial organs. Now, mechanical engineers from New York's Columbia University have unveiled a 3D-printed cheesecake made with seven ingredients. This is the most number of items ever used to print a single food product....
