The moon could have formed within hours after the gigantic impact between Earth and a Mars-sized protoplanet early in the solar system’s history. The theory arises from new simulations that take into account how the internal temperature of young protoplanets influenced their geological properties and, therefore, the collisions they suffered. This giant impact scenario has … Read more
The cd command, short for “change directory,” is one of the most fundamental commands on Linux. It’s how you navigate the Linux terminal — moving between different working directories. That said, cd is an old-school way to navigate the Linux file system, and several modern alternatives have emerged that make the process faster and easier. … Read more
Melbourne’s largest wastewater treatment plant is also one of the best places for bird watching in Australia. About 300 species appear there, and some of them fly in from Siberia. In the 1880s Melbourne had a problem it could no longer ignore. Open sewers emptied into the Yarra River and Hobsons Bay, and cholera and … Read more
Quantum computers are supposed to have capabilities far beyond conventional ones, but verifying that they actually have them is surprisingly difficult, because verifying their results can require calculations that become prohibitively difficult for classical machines. This is the problem of quantum verification, and a new experiment has found an ingenious solution: a game that tests … Read more
A B-52G on a Strategic Air Command air warning mission was refueling over the Atlantic when the tanker crew told its commander that it had a fuel leak on its right wing. The tanker drove away. The bomber carried two Mk 39 Mod 2 thermonuclear weapons and fell near Seymour Johnson Air Force Base at … Read more
Researchers have located the planet’s largest known octopus nursery deep off the California coast, documenting 5,718 animals on 2.5 hectares and estimating around 20,000 around Davidson Seamount. Known as Octopus Garden, the nursery is located about 10,500 feet below the surface off the central coast of California. According to a statement issued by the Monterey … Read more
Most dinosaur fossils are discovered in northeastern Thailand, in Phu Wiang National Park, which is why this region is jokingly called “Thailand’s Jurassic Park.” Thitiwoot Sethapanichsakul, a PhD student at University College London, told the AFP news agency that the dry climate and sparse vegetation leave fossil-bearing rocks exposed and easy to find.
Artist’s concept of an asteroid near Earth. Experts said that a small asteroid impact will occur over the Indian Ocean near Australia today, September 6, 2026, at 16:07 UTC. The object should harmlessly impact Earth’s atmosphere near northwest Australia and create a bright meteor. Image via Batman111/ Pixabay. Small asteroid impact today near Australia The … Read more
A persistent area of unusually warm tropical ocean helped intensify snowfall over East Antarctica, contributing to a net temporary increase in ice sheet mass of about 695 billion tons, according to a new study published in Nature on August 19. The researchers found that sustained warming in the tropical warm pool during 2021-23 triggered a … Read more
