NASA's Nancy Grace Roman Space Telescope Clears Final Tests, Readies for Launch After Budget Battle

The Nancy Grace Roman Space Telescope has cleared its final tests and is preparing for launch following a period of uncertainty about its future. The observatory recently completed a comprehensive testing program designed to verify its readiness for the harsh environment of space. These tests ensure the telescope's

AI Analysis of Standard Mammograms May Help Identify Heart Disease Risk in Women

A new study suggests that artificial intelligence could repurpose routine mammogram images to screen for cardiovascular risk in women. Researchers trained AI models on mammograms—X-ray images of breast tissue—to identify patterns associated with heart disease, a condition that often goes undetected in women due to different symptom presentations

NASA's Failed Attempt to Rescue the Falling Swift Telescope Highlights Challenges of Satellite Servicing

The Swift Gamma Ray Burst Mission, a veteran NASA observatory launched in 2004, had outlived its expected operational lifetime but faced an unexpected crisis when it began drifting from its planned orbit. NASA mounted a rescue effort, but the mission ultimately fell apart, according to reports. The failed rescue attempt

The Growing Water Footprint of AI: Location and Technology Matter

Data centers powering AI systems require substantial cooling to function, and as the industry expands, so does its water footprint. A recent Ars Technica analysis examines how much of a problem AI's water use actually represents. The core issue is straightforward: servers generate heat, and removing that heat

Astronomers Detect Hidden Companion Star Orbiting Betelgeuse

Astronomers have announced the discovery of a hidden companion star orbiting Betelgeuse, the well-known red supergiant located in the constellation Orion. The finding, described by one researcher as prompting them to "jump from their chair" upon realization, represents a significant addition to our understanding of this iconic star
