By Katie Hunt, CNN (CNN) — The puzzle pieces of Earth’s rocky crust are slowly and steadily moving — a process known as plate tectonics. These dynamic movements helped to create the habitats and climate that fostered the emergence of life on our planet, but exactly when the geological process first emerged has been a

By Jackie Wattles, CNN (CNN) — NASA’s new chief is reshaping the space agency’s goals, unveiling at an event in Washington, D.C., on Tuesday an ambitious vision that includes revamped plans for a moon base. While the space agency has long had its sights set on creating a settlement on the moon for astronauts to

By Ella Nilsen, CNN (CNN) — The Trump administration announced it will pay nearly $1 billion to French energy giant TotalEnergies in exchange for the company abandoning plans to build offshore wind farms in the Atlantic Ocean and instead pursue fossil fuel projects in the US. The current administration has thrown up roadblocks at every

By Katie Hunt, CNN (CNN) — The tragic tale of Harold, the king who lost England to William the Conqueror in an infamous battle, still looms large in British popular culture.

By Ella Nilsen, CNN (CNN) — Rainbow trout is a prized catch for fisherman on the Northern Cheyenne reservation, in the high plains of southeastern Montana. “The men in my family like to go fishing; they cook them right there because it’s fresh,” said Charlene Alden, the tribe’s environmental protection director. But there is an

By Katie Hunt, CNN (CNN) — Years before emails, internet banking, cloud servers and cryptocurrency wallets, two scientists devised a way to keep secrets perfectly safe and indecipherable to eavesdropping outsiders. Their 1984 work depended on the hidden, counterintuitive world of quantum physics, which governs the way the world works at the smallest, subatomic scale,

By Jacopo Prisco, CNN (CNN) — Like tiny photobombers, cosmic anomalies resembling small, bright red points show up in almost every snapshot taken by the most powerful space telescope ever made. Astronomers now call them little red dots, or LRDs, but there is no agreement yet on what exactly they are. Since NASA’s James Webb

By Jack Bantock, CNN (CNN) — Time and time again, Hollywood has embraced an imminent apocalypse, as films like “2012” beamed the fictionalized end of the world onto the big screen.
