NASA spacecraft tracks comet SWAN in incredible 40-day timelapse — and even glimpses interstellar invader 3I/ATLAS (video)
Comets are famous for making brief, dramatic appearances in our skies, but one icy wanderer just received an unprecedented level of attention from one of NASA's newest spacecraft. Comet SWAN moving across the sky in PUNCH images taken from Sept. 11 to 22, 2025. (Image credit: NASA/Southwest Research Institute)The video above stitches together hundreds of PUNCH images taken from Aug. 25 to Oct. 2, showing the comet gliding between two bright objects — Mars at the top and the star Spica in the constellation of Virgo at the bottom. Because the images were not fully processed before being combined, boundaries between individual snaps remain visible as thin black seams, the statement read.Comet C/2025 R2 (SWAN) was first spotted in September by Ukrainian amateur astronomer Vladimir Bezugly, who noticed the icy visitor a bright blob...
AI in Healthcare: Revolutionising Patient Care and Diagnostics
Artificial Intelligence (AI) is not only transforming business operations but also revolutionising healthcare. From early disease detection to streamlined patient care, AI is empowering doctors, hospitals, and patients to achieve better outcomes with greater efficiency. In 2025, healthcare systems worldwide are increasingly adopting AI tools, reshaping the patient journey and driving innovations once considered science fiction.
The Promise of AI in Modern Healthcare
AI in healthcare is built on three pillars: data-driven insights, automation of repetitive tasks, and personalisation of treatments. Medical professionals generate vast amounts of data daily—patient histories, scans, lab results, and prescriptions. Traditionally, this data was underutilised, but now AI systems can process it rapidly and offer actionable insights.
With algorithms that detect patterns beyond human capability, doctors can make more accurate diagnoses. For instance, AI can flag early signs of cancer in an MRI...
