Geologists have discovered the world’s oldest known impact crater; it sits in the heart of Western Australia’s ancient Pilbara region. An analysis of rock layers in the region suggests a crater at least 62 miles (100 kilometers) wide was carved after a large space rock struck Earth roughly 3.47 billion years ago, when our planet … Read more
Scientists warn that the Trump administration’s abrupt firing of hundreds of weather forecasters and climate experts across NOAA will curtail important climate research and could result in preventable deaths during extreme weather events and related disasters. Over 800 employees across most divisions of the National Oceanic and Atmospheric Administration (NOAA) — a premier U.S. federal … Read more
Black holes may leak more energy to their surroundings than previously suspected — and the faster these voids spin, the more efficient this energy extraction seems to be. With this in mind, a team of scientists has discovered how the disks of gas and dust that swirl around black holes can become the powerful engines … Read more
NASA’s diverse astronaut corps was an example of the agency’s support for diversity and inclusion.Credit: James Blair/NASA/JSC In the corridors of NASA buildings across the United States, Pride flags and pictures celebrating women in science are being taken down. Scientists are adding space-mission stickers to their laptops to cover ones that displayed rainbows and other … Read more
Astronomers are expressing disappointment and alarm as the federally-funded Rubin Observatory altered the biography of renowned astronomer Vera Rubin, for whom the facility is named, on its website. The amended version curtails her legacy of championing women in science and removes all mentions of the observatory’s efforts to reduce barriers for women and other historically … Read more
Having launched on January 9, 2024 by the Chinese Academy of Sciences, the Einstein Probe detected several new events during its commissioning phase. Last October, Yuan Weimin, the spacecraft’s principle investigator, told China Central Television that the X-ray observatory had already discovered around 60 very strong transient celestial objects, close to a thousand potential transients, … Read more
NEW ORLEANS — Scientists continue to advance the process of updating the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Scales, with the next steps expected to be taken as early as this year. Just like there’s a classification system for hurricanes and tornadoes, space weather storms that develop and pose threats to Earth have … Read more
Scientists believe that two asteroids might be fragments of long-lost “planetary embryos” from the early solar system. These embryos, somewhere between small planetesimals and fully formed planets, were abundant during the solar system’s formative stages and played a critical role in planetary formation. Two asteroids in the main asteroid belt between Mars and Jupiter, (246) … Read more
Researchers have obtained the first conclusive evidence of an elusive third class of magnetism, called altermagnetism. Their findings, published Dec. 11 in the journal Nature, could revolutionize the design of new high-speed magnetic memory devices and provide the missing puzzle piece in the development of better superconducting materials. “We have previously had two well-established types … Read more
Scientists have discovered that some supermassive black holes rotate much more rapidly than expected. The discovery came as the result of a new form of “black hole archeology” that links black hole spins to the gas and dust they have consumed to grow over 7 billion years of cosmic history. The findings, courtesy of the … Read more
