It would take four centuries to reach its destination. It would carry 2,400 people who would never see the world they left or the world their descendants would eventually inhabit. It would need to generate its own gravity, grow its own food, recycle every molecule of water and air, and preserve enough technical and cultural
WASHINGTON — A new SpaceX initiative to provide space traffic coordination services has attracted attention and praise in part because of the conditions it places on users of it. SpaceX announced in late January Stargaze, a space situational awareness (SSA) system. Stargaze uses images from star tracker cameras on its nearly 10,000 Starlink satellites to

Sodium-ion batteries are emerging as a promising option for cleaner, more sustainable energy storage. Researchers at the University of Surrey have identified a surprisingly simple way to improve their performance by keeping water inside a critical battery material instead of removing it. Lithium-ion batteries currently dominate the market, but they depend on costly materials that
A 215-million-year-old crocodylomorph discovered in the United Kingdom has been identified as a new species, Galahadosuchus jonesi. The fossil, unearthed in 1969 but only recently recognized as distinct. The find sheds light on a little-known chapter of early crocodile evolution during the Late Triassic, a period that predates the Triassic-Jurassic mass extinction. It also highlights
The interior of the Moon’s Shackleton crater is shrouded in eternal darkness. This not only makes it one of the most mysterious geologic features of the lunar south pole but also one of the most promising for harboring precious resources—most notably water ice. The prospect of extracting water from the Moon is tantalizing. An in
Scientists have linked a sudden burst of rust-red water at Antarctica’s Blood Falls to a measurable drop in the glacier sitting above it. That connection shows the red flow is not just a surface stain, but a visible signal of pressure changes and hidden water movement deep beneath the ice. A signal in ice
A new experiment involving anesthetized rats is fueling one of the most audacious ideas in neuroscience: that consciousness could arise from quantum processes inside the brain. Published in August 2024 in the peer-reviewed journal eNeuro, the study adds experimental weight to the long-debated Orch OR theory developed by Nobel Prize-winning physicist Roger Penrose and anesthesiologist
An artist’s impression of the massive shark that lived 115 million years ago (Credit: Polyanna von Knorring, Swedish Museum of Natural History) In the early 1990s, five unusually large shark vertebrae were unearthed along the rugged coastline near Darwin, Australia. At the time, they were thought to be the remains of a great white shark,
Lower Paxton Township supervisors chose a new chair on Tuesday night. Pamela Thompson resigned from that position last week. The board’s vice chair, John Campbell was elected as chair. Kate Scheib was elected vice chair and will also hold onto her position as treasurer. Robin Lindsey will remain secretary and Charles Stuart will remain assistant
