gizmodo.com Passant Rabie 2025-08-29 12:05:27

A little over a year ago, scientists in Australia picked up a brief burst of electromagnetic radiation. The pulse was so strong that it eclipsed all other signals coming from the sky, but its origins were unknown. After digging through the data, the team discovered that the source wasn’t a distant celestial object but rather a zombie satellite left to orbit Earth with no purpose. NASA’s Relay-2 launched on January 21, 1964, two years after its predecessor, Relay-1, was sent to orbit. The pair w

The National Science Foundation just shared the first images captured by the Vera C. Rubin Observatory, a sample of the footage it'll capture as part of a planned decade-long survey that's starting later in 2025. The project, dubbed the "Legacy Survey of Time and Space" is predicted to lead to the discovery of "millions of new asteroids within the first two years" the survey is running. In just a 10 hour period, the National Science Foundation says that the Rubin Observatory "discovered 2,104 n

gizmodo.com Jenna Jordan 2025-09-01 06:00:54

At least 14 nuclear scientists are believed to be among those killed in Israel’s Operation Rising Lion, launched on June 13, 2025, ostensibly to destroy or degrade Iran’s nuclear program and military capabilities. Deliberately targeting scientists in this way aims to disrupt Iran’s knowledge base and continuity in nuclear expertise. Among those assassinated were Mohammad Mehdi Tehranchi, a theoretical physicist and head of Iran’s Islamic Azad University, and Fereydoun Abbasi-Davani, a nuclear e

Charlize Theron’s 6 Best Genre Roles

gizmodo.com Cheryl Eddy 2025-09-07 00:20:16

Charlize Theron can do any genre—she has an Oscar for playing a serial killer, and she gave a standout comedic performance on Arrested Development. She’s also a gifted action star, as seen in her appearances in Atomic Blonde and the Fast & Furious movies, a series which skirts the edge of sci-fi. But you don’t need to qualify anything when it comes to Theron’s fondness for sci-fi and fantasy.

Spanish blackout report: Power plants meant to stabilize voltage didn’t

arstechnica.com Unknown 2025-09-07 08:15:24

The blackout that took down the Iberian grid serving Spain and Portugal in April was the result of a number of smaller interacting problems, according to an investigation by the Spanish government. The report concludes that several steps meant to address a small instability made matters worse, eventually leading to a self-reinforcing cascade where high voltages caused power plants to drop off the grid, thereby increasing the voltage further. Critically, the report suggests that the Spanish grid
