NASA’s James Webb Space Telescope has revealed early galaxies that appear almost as old as the universe itself. By analyzing 31 galaxies at high redshift, researchers estimated stellar ages of around 600 million years—close to the universe’s age at that epoch. One galaxy may even seem older than the universe, posing a potential challenge to the standard Lambda-C…

NASA’s SPHEREx telescope captured a dramatic outburst from interstellar comet 3I/ATLAS after its close solar flyby in October 2025. Infrared observations in December revealed water vapor, carbon dioxide, methanol, methane, and cyanide erupting from the comet’s nucleus. Scientists say the chemical makeup suggests formation in a relatively warm environment beyond ou…

Microsoft has highlighted several risks with artificial intelligence (AI) agents in its latest security report. The most interesting insight is about “AI double agents,” which are basically agents with excessive privileges but not enough safeguards. This makes them vulnerable to prompt engineering attacks by bad actors, and turns them into “double agents.”

A new theoretical study suggests dark matter may not exist, proposing instead that gravity behaves differently across vast cosmic distances. By modifying how gravity weakens over scale, the research explains galaxy rotation and lensing effects without unseen particles, raising questions about long-standing cosmological models and inviting a fresh look at gravity’s h…

NASA’s SPHEREx telescope has observed interstellar comet 3I/ATLAS unexpectedly brightening as it leaves the solar system. The comet released water vapour, carbon dioxide, and organic compounds months after its closest solar approach. Scientists say the findings provide a rare chemical snapshot of material formed around another star, helping compare planetary ingredi…

The Gujarat government on Monday signed a Letter of Intent with Starlink to work together on providing high-speed satellite internet across the state. The agreement, exchanged in Gandhinagar with SpaceX subsidiary Satellite Communications Private Limited, aims to connect remote, border, and underserved areas where telecom networks are weak, as part of Gujarat’s Digi…
