By Ashley Strickland, CNN (CNN) — Astronomers with the European Space Agency’s Euclid mission have captured an unprecedented look at a rare cosmic phenomenon — and they made the observations purely by happenstance. Their discovery is tied to some of the earliest data from the Euclid telescope, which launched in July 2023 to study the

By Katie Hunt, CNN (CNN) — Unprovoked attacks by sharks declined sharply in 2024, with 47 incidents logged worldwide, down 22 from the previous year and significantly below a 10-year average of 70, according to new figures released Tuesday. The United States experienced the highest number of unprovoked attacks by sharks, with 28 reported incidents,

By Ashley Strickland, CNN (CNN) — Look up this week for February’s full snow moon and to catch the last glimpse of a visible parade of planets in the night sky before they fade from view. This phase of the moon will peak at 8:53 a.m. ET Wednesday, but the glowing orb will appear full

By Brenda Goodman and Ella Nilsen, CNN (CNN) — Scientists, faculty and staff at Emory University received an alarming email Saturday: An announcement of funding caps from the National Institutes of Health meant scientists and their labs at research institutions across the US would need to tighten their belts. For the Atlanta-based school, a preeminent

By Laura Paddison, CNN (CNN) — Swaths of the US may be grappling with frigid weather, but for the planet as a whole, heat records are being obliterated — and it spells very bad news. Two new studies conclude it’s a signal the planet is likely on track to breach the Paris climate agreement goal

By Ashley Strickland, CNN (CNN) — The challenge of unearthing lost things and solving inscrutable puzzles is a driving force in the world of science. Such breakthroughs rarely happen in the derring-do fashion of the “Indiana Jones” films that inspired me to search for lost cities in my childhood backyard. Rather, some of the groundbreaking

By Jackie Wattles, CNN (CNN) — In a Friday afternoon email to NASA staff, the agency’s acting chief asked employees to embrace the philosophy of Elon Musk’s Department of Government Efficiency, or DOGE, as workers express concern over recent directives and anti-diversity, equity, inclusion and accessibility (DEIA) communications. In her email, NASA Acting Administrator Janet

By Ashley Strickland, CNN (CNN) — A recently discovered asteroid that has captured the attention of the astronomy community now has a slightly increased risk of affecting Earth. Named 2024 YR4, the asteroid has a 2.2% chance of hitting our planet on December 22, 2032, according to the European Space Agency. The risk assessment has

By Laura Paddison, CNN (CNN) — The existence of the US Agency for International Development hangs in the balance. President Donald Trump is racing to shut it down, declaring it a waste of money and run by “lunatics.” But experts warn this plays straight into the hands of the very country he considers to be

By Jackie Wattles, CNN (CNN) — Seven years after SpaceX launched Elon Musk’s cherry red sports car into orbit around our sun, astronomers unwittingly began paying attention to its movements once again. Observers spotted and correctly identified the vehicle as it started its extraterrestrial excursion in February 2018 — after it had blasted off into

By Katie Hunt, CNN (CNN) — Scientists have made a leap forward in understanding the pattern and structure of turbulence — a natural phenomenon observed in fluids such as moving water, ocean currents, chemical reactions, blood flow, storm clouds, plumes of smoke and even the plasma of stars. While turbulent flow is chaotic and irregular,

By Katie Hunt, CNN (CNN) — Scholars are decoding an ancient scroll that was one of hundreds charred to a crisp during the eruption of Mount Vesuvius in AD 79. The artifact, which is kept at the University of Oxford’s Bodleian Libraries in the United Kingdom, is the fifth intact Herculaneum scroll to be virtually

By Ashley Strickland, CNN (CNN) — If the near-Earth asteroid Bennu were to collide with Earth in the future, the space rock could cause substantial global damage, even though it’s a fraction of the size of the asteroid that wiped out the dinosaurs, according to new research. Astronomers estimate that Bennu has a 1 in

By Katie Hunt, CNN (CNN) — A near complete skull fossil found in Antarctica has revealed the oldest known modern bird — a mallard duck-size creature related to the waterfowl that live by lakes and oceans today, a new study has found. The 68 million-year-old fossil belongs to an extinct species of bird known as

By Jack Guy, CNN (CNN) — Some great apes realize when a human partner doesn’t know something and are capable of communicating information to them to change their behavior, a new study shows. Researchers from Johns Hopkins University studying bonobos found that they would point to where treats were hidden if they could see their

By Ashley Strickland, CNN (CNN) — About 3.8 billion years ago, two massive canyons likely formed on the moon in a span of less than 10 minutes, according to new research. The extraordinary formations, each comparable in size to Earth’s Grand Canyon, are hidden on the far side of the moon — the side that

By Laura Paddison, CNN (CNN) — Images from space reveal an enormous X-shaped building rising up from rocky terrain in southwestern China. This is a huge nuclear fusion research facility, analysts say, and it could be a sign China is leaping ahead in the quest to harness this futuristic energy source. It could also mean
