an international collaboration of cosmologists has reached a new level of precision in measuring the Hubble constant. The Hubble constant is crucial in understanding the rate of expansion of the universe and, by extension, estimating the universe’s age. This collaborative effort unites various measurement techniques, refining them to produce a unified and highly accurate value.
It’s a tail as old as time. Scientists may have discovered the world’s oldest butthole after unearthing the nearly 300-million-year-old impression of a reptile’s backend in Germany, per an upcoming study in the journal Current Biology. “Such soft-tissue structures are extremely rare in the fossil record – and the further back we look in Earth’s
In the rugged hills of western Iran, an ancient discovery is challenging everything we thought we knew about early human societies. What was once considered a minor site has now revealed a fascinating glimpse into the complex administrative systems of prehistoric times. At Tapeh Tyalineh, archaeologists uncovered thousands of seal impressions, figurines, and tokens that

NASA and its international partners will receive scientific research samples and hardware when a SpaceX Dragon spacecraft departs the International Space Station on Thursday, Feb. 26, and returns to Earth. Watch NASA’s live coverage of the undocking and departure of the agency’s 33rd SpaceX Commercial Resupply Services mission starting at 11:45 a.m. EST on NASA+,
Humans have changed a lot over the past few hundred millennia. We evolved from ancient apes, which are believed to have in turn evolved from sea creatures that existed in the distant, distant past, and Homo sapiens have only existed for a paltry 300,000 years. Some animals, however, have remained almost exactly the same for
Scientists have resolved a longstanding mystery about the Great Unconformity, a huge gap in the geological record that shows up across the world and has inspired speculation for more than 150 years, reports a study published on Monday in Proceedings of the National Academy of Sciences. The unconformity shows up around the world when sedimentary
For the first time, a much younger version of the Sun has been caught red-handed blowing bubbles in the galaxy, by astronomers using NASA’s Chandra X-ray Observatory. The bubble – called an “astrosphere” – completely surrounds the juvenile star. Winds from the star’s surface are blowing up the bubble and filling it with hot gas
Archaeologists recently unearthed a series of animal skulls in a Neanderthal cave in Spain, sparking new questions about the rituals and symbolic practices of early humans. The skulls, some of which belong to horned animals, weren’t placed there all at once, but accumulated over a long period. This repeated behavior hints at a deeper, structured
Earthquakes are one of many natural phenomena that, despite technological advances, we’ve yet to predict in advance. Researchers in Japan—a country frequently hit by devastating earthquakes—propose we look for an otherworldly source: the Sun. In a recent paper published in the International Journal of Plasma Environmental Science and Technology, the researchers consider the possibility that
