Global energy-related carbon dioxide emissions rose by 6 percent in 2021 to a record 36.3 billion metric tons, their highest ever level, the International Energy Agency said Tuesday. “The increase in global CO2 emissions of over 2 billion metric tons was the largest in history in absolute terms, more than offsetting the previous year’s … Read more
Physicists in Australia have programmed a quantum computer half a world away to make, or at least simulate, a record-size time crystal—a system of quantum particles that locks into a perpetual cycle in time, somewhat akin to the repeating spatial pattern of atoms in an actual crystal. The new time crystal comprises 57 quantum particles, … Read more
How does an animal as big as a semitruck move around? That’s a question scientists have long asked about sauropods, the largest known dinosaurs, which may have weighed as much as 70 tons. Did they walk like a giraffe, picking up their two left and right legs in a dignified march? Or like an elephant, … Read more
The biggest airplane ever built, Stratolaunch’s Roc carrier aircraft, just aced its fourth test flight. Roc, which will eventually haul hypersonic vehicles into the air, successfully finished its latest flight on Thursday (Feb. 24), a jaunt that came on the heels of another test flight in January. Roc lifted off from the Mojave Air and … Read more
Astronomers have just found an absolute monster of a galaxy. Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That’s 16.3 million light-years long, and constitutes the largest known structure of galactic origin. The discovery highlights our poor understanding of these colossi, and what drives their … Read more
Scientists have created the first map of a colossal supercluster of galaxies known as Laniakea, the home of Earth’s Milky Way galaxy and many other. This computer simulation, a still from a Nature journal video, depicts the giant supercluster, with the Milky Way’s location shown as a red dot. (Image credit: Nature Video) The biggest … Read more
Astronomers have calculated the size of a ‘mega comet’ originating in the Oort Cloud, a cluster of icy bodies that surrounds our solar system Space 4 February 2022 By Jonathan O’Callaghan Illustration of the comet Bernardinelli-Bernstein as it might look in the outer solar system NOIRLab/NSF/AURA/J. da Silva Astronomers have confirmed that a “mega comet” … Read more
The sun may appear to be the largest star in the sky but that’s just because it’s the closest. On a stellar scale, it’s really quite average — about half of the known stars are larger; half are smaller. The largest known star in the universe is UY Scuti, a hypergiant with a radius around … Read more
For the first time, a pack of orcas – also known as killer whales – have been observed hunting and killing blue whales, the largest animal on the planet. According to a report published in Marine Mammal Science, the scientific community has long debated if orcas can hunt the massive blue whales. But this question … Read more
