Jupiter is the largest planet in the solar system and the fifth planet from the sun. The gas giant features beautiful banded cloud layers; a set of thin, dusty rings; the famous Great Red Spot; and dozens of varied moons. How did Jupiter get its name? As the fourth-brightest object in Earth’s sky — after … Read more
Prehistoric giants used to populate the Earth. These behemoths included mighty dinosaurs, airplane-size pterosaurs, massive crocodiles and snakes, and even armadillos the size of cars. But today, there are just a few big animals on our planet. What happened? Why aren’t there many giants left anymore? First of all, there’s plenty of fossil evidence that … Read more
Antarctica’s so-called Doomsday Glacier is losing ice at its fastest rate in 5,500 years, raising concerns about the ice sheet’s future and the possibility of catastrophic sea level rise caused by the frozen continent’s melting ice. The finding comes from a study of prehistoric sea-deposits found on the shores surrounding the “doomsday” Thwaites Glacier and … Read more
A team of Chinese scientists has discovered a giant new sinkhole with a forest at its bottom. The sinkhole is 630 feet (192 meters) deep, according to the Xinhua news agency, deep enough to just swallow St. Louis’ Gateway Arch. A team of speleologists and spelunkers rappelled into the sinkhole on Friday (May 6), discovering that … Read more
If you look at an evolutionary diagram, you can see where Homo sapiens branched off from other primates. You can see where apples branched off from the rest of the rose family. But you won’t see where trees branched off from other plants. That’s because they never did. Trees are not a species, or even … Read more

Roaming Mars is a lonely existence for NASA’s Perseverance, but the exploratory rover now has a traveling companion: a hitchhiking “pet rock” that got stuck in one of its wheels. Luckily, the Martian stone won’t impact the rover’s science mission and is only a minor inconvenience — like having a pebble stuck in your shoe. … Read more
Thousands of mysterious viruses that were recently discovered lurking in the world’s oceans may exert huge influence over the ecosystems, in part by “reprogramming” the hosts they infect, scientists reported. The new research, published Thursday (June 9) in the journal Science (opens in new tab), focuses on viruses that contain RNA, a molecular cousin of … Read more
When mountaineers climb Mount Everest, they routinely carry oxygen cylinders, devices that allow them to breathe freely at high altitudes. This is necessary because the closer you get to the edge of Earth’s atmosphere, the less oxygen there is available compared with the plentiful amounts found at sea level. This is just one example of … Read more
