Phys.org: Mysterious Fast Radio Burst Turns Out to be From Long-dead NASA Satellite

A team of astronomers and astrophysicists affiliated with several institutions in Australia has found that a mysterious fast radio burst (FRB) detected last year originated not from a distant source, but from one circling the planet—a long-dead satellite. The team has posted a paper outlining their findings on the arXiv preprint server…The findings could lead to the development of new tools for studying signals coming from space, whether near or far, and possibly new ways to monitor the movement of dead satellites.

Futurism: Nobel Prize Winner Warns About Astronomers Using AI to Make Discoveries

A team of astronomers say they’ve gleaned the mysterious traits of our galaxy’s black hole by probing it with an AI model. But a pretty big name on the field is throwing a little bit of cold water on their work. Just a little bit. Reinhard Genzel, a Nobel laureate and an astrophysicist at the Max Planck Institute, expressed some skepticism regarding the team’s use of AI, and the quality of the data they fed into the model. “I’m very sympathetic and interested in what they’re doing,” Genzel told Live Science. “But artificial intelligence is not a miracle cure.”

Swedish Institute of Space Physics: Swedish-built Instrument Discovers New Type of Particle on the Lunar Surface

A space instrument, built by the Swedish Institute of Space Physics (IRF), has for the first time detected negative hydrogen ions on the surface of the Moon – a type of particle never seen there before. The discovery was recently published in the scientific journal Nature Communications Earth and Environment.
