If that sounds like an FM radio band, it's no coincidence. Starlink satellites bounce FM radio shows back down to the Earth. For telescopes carefully located in radio-quiet zones, that's not ideal.

Radio telescopes saw a strange burst of unknown energy in June 2024. Now we know it was from Relay 2, an early telecommunications satellite.

Astronomers from the International Center for Radio Astronomy Research (ICRAR), in collaboration with international teams, have made a startling discovery about a new type of cosmic phenomenon.

Researchers traced long, bright radio pulses, combined with X-rays, to an intriguing cosmic object 15,000 light-years from Earth, according to a new study.

The ALMA radio telescope array in the Atacama Desert temporarily halted operations after a rare snowfall blanketed the base camp last week.
