NASA Archive Reveals Hypersoft X-ray Beacons in Nearby Galaxies

A team reexamined archival data from NASA’s Chandra X-ray Observatory (1999–2017) and found a new class of bright, very low-energy X-ray sources in six nearby galaxies, dubbed hypersoft X-ray beacons. They identified 84 such objects (rising to 145 after adding four more galaxies), which could be precursors to Type 1a supernovas or exotic systems like white dwarfs shifting emission into the extreme ultraviolet and hypersoft X-rays, or compact black hole–star configurations. The discovery, led by Mustafa Muhibullah of the University of Alabama, shows these objects were hiding in plain sight in old data and could help solve puzzles about stellar deaths and galaxy ionization.

Narwhal Tusks Unveil Twin Spiral Structure Through 3D X-Rays

Narwhal Tusks Unveil Twin Spiral Structure Through 3D X-Rays

Researchers using advanced 3D X-ray imaging from multiple synchrotrons revealed that the narwhal’s tusk is a double spiral: the outer cementum twists left, the inner dentin twists right, forming a biological counterbalance that enhances strength. The tusk, which is the narwhal’s left canine and can exceed two meters, grows through the jaw and lip and is commonly seen as a sexual signal, though its exact function remains debated. The findings, published in Nature, also suggest the growth pattern is genetically programmed and that the tusk could serve as a record of environmental change over the animal’s roughly 80-year lifespan, potentially inspiring new materials design.

Orbital X-ray breakthrough: first diagnostic images captured in microgravity

Four first-time astronauts aboard SpaceX Fram2 used a portable X-ray unit with roughly four hours of training to capture diagnostic images in orbit; three radiologists on the ground judged the images clinically usable to identify fractures or foreign objects, marking the first in-space diagnostic X-rays and highlighting portable imaging as a key tool for future deep-space missions where hospital care is unreachable.

First In-Orbit X-Rays Spark a New Era in Space Medicine

Astronauts on a civilian mission performed diagnostic-quality X-ray imaging in orbit with a portable wireless system, capturing images of hands, forearms, chests, abdomen, and pelvis that radiologists on Earth deemed suitable for diagnosis. This marks the first in-space X-ray images and could enable rapid medical assessments and onboard hardware checks on future missions, though imaging time and keeping subjects still pose challenges. AI-assisted analysis and more rugged, compact systems are anticipated to expand use on Moon and Mars missions.

Orbiting X-Rays Break Ground in Space Medicine

SpaceX’s Fram2 mission conducted the first in-orbit medical X-ray scans with a portable X-ray device, capturing diagnostic-quality images of the hand, forearm, abdomen, pelvis, and chest that were reviewed by three radiologists. The inflight results show radiography can supplement ultrasound for astronaut health, diagnose injuries, and even assess equipment or space-suit integrity, marking a path toward more capable space diagnostics. Future work will aim to miniaturize and harden X-ray systems for vacuum and deep-space use, with real-time imaging guidance for astronauts on Moon missions.

X-ray Dot Bridges Little Red Dots and Growing Black Holes

X-ray Dot Bridges Little Red Dots and Growing Black Holes

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 Shows Off X‑Ray After Major Tibia Injury

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 shows off ‘bionic’ X-ray after sixth surgery from Milan crash

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.

AI predicts future X-rays, revolutionizing osteoarthritis care

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.
