Astronomers have detected one of the darkest objects ever seen at a record cosmic distance—only with the assistance of gravity. The discovery is an important step toward the observation of dark matter ...

Using the Ultraviolet/Optical Telescope aboard NASA’s Neil Gehrels Swift Observatory, astronomers have detected hydroxyl (OH) gas — a chemical fingerprint of water — from the interstellar object ...

The Raspberry Pi 500 (and 400) systems are versions of the Raspberry Pi built for people who use the Raspberry Pi as a general-purpose computer rather than a hobbyist appliance. Now the company is ...

When Raspberry Pi released the Pi 500, as essentially an RPi 5 integrated into a chiclet keyboard, there were rumors based on the empty spots on the PCB that a better version would be released soon.

Sunfounder’s Pironman line of cases for the Raspberry Pi 5 do a lot more than cover up and protect the single-board computer. Models like the Pironman 5, Pironman 5-MAX, and Pironman 5-Mini also give ...

The Starter Kit GenX320 is a power-efficient, event-based camera designed for the Raspberry Pi 5 that detects events with a latency of less than 150 μs, or the equivalent of about 10,000 FPS. The ...
