NASA's Chandra and JWST data reveal an X-ray-emitting 'X-ray dot' among the enigmatic little red dots, suggesting a transient, ultra-massive black hole stage—possibly a 'black hole star' where a dense gas cloud hides emissions and links these dots to early black hole growth.
Astronomers using Webb and Chandra have identified a unique X-ray–emitting object, 3DHST-AEGIS-12014, about 11.8–12 billion light-years away, that appears as a “little red dot” yet glows in X-rays. The finding could mark a transitional phase between dusty, obscured little red dots and ordinary growing supermassive black holes, offering a key clue to how SMBHs form in the early universe. If this interpretation holds, it would link the LRD population to SMBH growth; further observations are planned to confirm the scenario.
Lindsey Vonn shared an X‑ray showing extensive hardware in her leg from a complex tibia fracture she suffered during a downhill crash at the Milan Cortina Winter Olympics, detailing a lengthy recovery and multiple surgeries as she contemplates a comeback at 41; she had ruptured her ACL days before the Games and also mourned the death of her dog Leo during the tough period.
Lindsey Vonn shared an X-ray image after undergoing her sixth surgery (a six-hour procedure) following a severe crash at the Milan-Cortina 2026 Winter Games that left her tibia fractured. She said recovery has been slow and painful but is back in the United States as she continues treatment, with hopes of returning to the slopes one day despite a long road ahead.
Channing Tatum posted from his hospital bed after undergoing surgery for a separated shoulder, sharing X-ray images that show the break and a screw stabilizing the bones; he didn’t specify how the injury occurred, but he has support from girlfriend Inka Williams during recovery.
Recent research suggests that the relationship between ultraviolet and X-ray emissions in quasars has changed over billions of years, challenging long-held assumptions about the uniformity of matter surrounding supermassive black holes and impacting methods used to study the universe's structure and evolution.
NASA's satellite observations of the pulsar J1023 reveal that its energy output is primarily powered by a pulsar wind colliding with nearby material, with polarization data indicating a coherent, ordered magnetic process near the star, challenging previous models and providing insights into neutron star evolution.
Researchers at the University of Surrey have developed an AI system that can predict future knee X-ray images and assess disease risk, potentially transforming osteoarthritis treatment by enabling earlier and personalized care. The system, trained on a large dataset, outperforms existing tools in speed and efficiency and could lead to similar innovations for other chronic diseases.
A 65-year-old woman in South Korea with osteoarthritis had gold threads inserted during acupuncture, which were visible on X-ray and posed potential health risks, highlighting concerns about the safety and efficacy of gold-thread acupuncture.
Routine X-rays for diagnosing knee osteoarthritis may do more harm than good by increasing patient anxiety and unnecessary surgeries; clinical diagnosis based on symptoms and medical history is safer and equally effective, reducing costs and exposure to radiation.
Lamar Jackson's foot injury was confirmed to be minor after X-rays showed no damage, and he is expected to recover quickly. The article also highlights rookie Teddye Buchanan's versatility in learning multiple linebacker positions, wide receiver Devontez Walker's growing confidence, and the supportive coaching influence of Zach Orr and Roquan Smith. Overall, the Ravens are optimistic about their players' health and development as the season approaches.
NASA's new composite image combines X-ray data from Chandra and radio data from ATCA to reveal detailed structures of the pulsar B1509-58 and its surrounding nebula, highlighting complex magnetic filaments and interactions with supernova debris, while also raising questions about the nature of the supernova blast wave.
NASA's IXPE has measured a high polarization degree in the black hole IGR J17091-3624, challenging existing theories about the behavior of matter near black holes and suggesting the presence of phenomena like matter winds or fast plasma outflows.
Diamondbacks' star outfielder Corbin Carroll was initially cleared of injury after X-rays but later diagnosed with a wrist chip fracture via MRI, leading to his placement on the injured list amid a series of injuries affecting the team.
Astronomers have discovered an unusual repeating long-period transient signal, ASKAP J1832-0911, emitting every 44 minutes from deep in the Galactic Plane, which does not match known stellar objects and may indicate new physics or stellar evolution models. The source's sudden activation and intense brightness, along with correlated X-ray emissions, deepen the mystery, prompting further observations to understand these enigmatic signals.
