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
NASA has announced an earlier-than-expected target date to launch the next astronauts to the International Space Station (ISS). The agency is now targeting Feb. 11 for liftoff of the SpaceX Crew-12 mission, which will fly four astronauts to join the skeleton crew presently operating the orbital lab. A scant three are currently covering the maintenance
NASA is preparing to move forward with a key milestone as it readies the Space Launch System (SLS) rocket and Orion spacecraft for the Artemis II mission. A “wet dress rehearsal” allows launch teams to practice fueling and countdown procedures under conditions that closely mirror launch day, much like a full dress rehearsal before a
Black holes may be invisible, but their influence shapes galaxies, modern technology and humanity’s understanding of its own limits. That was the message shared last week by Priyamvada Natarajan, a theoretical astrophysicist at Yale University, during a session at the World Economic Forum in Davos, Switzerland. Natarajan, whose research focuses on cosmology, gravitational lensing and
Using a powerful AI tool, astronomers have combed through vast troves of data from NASA’s Hubble and found over 1,300 cosmic anomalies, more than 800 of which are new to science. The new research by David O’Ryan and Pablo Gomez from ESA (the European Space Agency) is published in Astronomy and Astrophysics. “Archival observations from
Jupiter’s moon Io is covered in hundreds of volcanoes, which spew fountains of lava that constantly refill impact craters on its surface with scorching molten lakes. A recent discovery of extreme volcanic activity on the Jovian moon tops any eruption previously detected on Io, proving that this chaotic world knows no bounds. NASA’s Juno mission

The findings reflect how post-publication commentary can help to identify errors or fraudulent results, say scientists. Previous research has shown that potentially problematic articles get
