The decrease in brightness is sometimes associated with low solar risk, and this false sense of security can lead to ...

The new technology will make it possible to more accurately detect objects and distinguish materials by their temperature trace, and in the future it may find application in thermal imagers, night ...

The laws of physics seemed to forbid a strange variety of black holes that could have zero temperature. Columnist Jacklin ...

Over the past year, efforts to put data centers into Earth’s orbit have moved from theoretical experiments to funded engineering programs.

At peak moments, such as on sunny summer days, the grid is flooded with solar energy, while during the evening and in winter, when energy tends to be most in demand, supply is less. In order to secure ...

Artificial intelligence (AI) and machine learning (ML) are moving from terrestrial data centres into space-qualified ...

Some 66 million years ago, an asteroid impact wiped out three-quarters of all plant and animal species on Earth, most notably taking down the dinosaurs. But exactly how that impact caused those ...

Editor's note: This is the second of three feature articles Ars is publishing to explore the financial, technical, and competitive dimensions of orbital data centers. Although the idea of putting data ...

Radiation therapy uses carefully targeted beams to destroy cancer cells while minimizing damage to healthy tissue. At Fred Hutch, patients have access to a full range of advanced radiation treatment ...

The Nuclear Regulatory Commission plans to end longstanding guidance that radiation exposure be “as low as reasonably achievable.” By Brad Plumer See more of our coverage in your search ...

Scientists used nanoscale gold metamaterials to supercharge heat transfer across tiny gaps, achieving up to four times more energy flow than similar conventional systems. The breakthrough could lead ...
