Astronomers have created the sharpest map yet of dark matter using deep observations from NASA’s James Webb Space Telescope. By analysing the gravitational distortion of hundreds of thousands of distant galaxies, the team traced invisible dark matter across a large region of the sky. The results confirm that dark matter forms the scaffolding around which galaxies an...

NASA has resumed efforts to reestablish contact with the MAVEN spacecraft after Mars emerged from solar conjunction. Engineers are using the Deep Space Network and studying recovered data from December 6 to determine what caused the communication loss and assess the spacecraft’s condition.

New observations from ESA’s Solar Orbiter show that solar flares can be triggered by cascading magnetic disturbances. During a close solar pass, the spacecraft captured fine details of twisted magnetic fields repeatedly breaking and reconnecting, creating a magnetic “avalanche” that amplified a small instability into a powerful flare. The findings offer new insi...

OpenAI CEO Sam Altman admitted that writing performance on ChatGPT has recently witnessed regression, and attributed it to selective training of the latest artificial intelligence (AI) model. The company hosted its inaugural town hall on Tuesday, inviting AI builders from across the ecosystem to ask questions and share feedback on its various products and services.
