Europa, one of Jupiter’s 95 moons, is encased in a shell of water ice, and researchers have just re-estimated its thickness. In 2022, NASA’s Juno spacecraft zoomed close to the moon’s surface. Information from this flyby has led researchers to conclude that, in the area where the flyby collected data, the moon’s layer of ice
“Any time there’s dynamic change, there’s the opportunity for new ideas to insert themselves,” Autry said in an interview with Ars. So Autry and others want to give people a chance to voice those ideas by launching the “Space Ideation Challenge.” A challenge for new ideas A prize purse of $125,000 will be awarded to
Deep in coastal mud and shallow lagoons, a tiny, brainless sea anemone is quietly using the same molecular playbook that helps human embryos decide where to put a back and a belly. A new study from the University of Vienna shows that the starlet sea anemone Nematostella vectensis builds its body using a signaling system
It was a groundbreaking discovery. Scientists have found previously concealed fault lines along California’s north coast, sparking concerns that we could be drastically underestimating the earthquake risk in the region, per a seismic study published in the journal “Science.” “If we don’t understand the underlying tectonic processes, it’s hard to predict the seismic hazard,” declared study

Archaeologists in Greece have discovered 430,000-year-old handheld wooden tools, the oldest surviving examples of their kind in the world, a new study finds. The two tools, found on the Peloponnese peninsula in southern Greece, were created by an unidentified hominin species that predates modern humans. “The objects represent the oldest hand-held wooden tools ever found,
Almost a hundred new animal species that survived a mass extinction event half a billion years ago have been discovered in a small quarry in China, scientists revealed Wednesday. The treasure trove of fossils offers a rare glimpse into a cataclysmic event that brought a sudden end to the greatest explosion of life in our
Russia is quietly testing a new plasma propulsion system that, if it performs as claimed, could dramatically change how long it takes to travel to Mars. Early results suggest a leap in speed and efficiency that has drawn attention precisely because it is not coming from NASA or private U.S. companies such as SpaceX. The
Researchers using the James Webb Space Telescope have found a galaxy that is offering new data about the early stages of the universe’s existence. The latest discovery shared by astronomers is about a bright galaxy dubbed MoM-z14. According to the team, this galaxy existed 280 million years after the Big Bang. The sounds like a
A Stone Age person buried 12,000 years ago in a cave in Italy had a rare genetic disorder that shortened her arms and legs, a new study finds. A DNA analysis of her skeleton revealed that she was a teenage girl who had a rare form of dwarfism. The finding is the earliest DNA diagnosis
