Take a photograph of the night sky, far away from any urban lights, and you stand a good chance of capturing the telltale streak of a satellite passing overhead. For any ground-based telescope ...

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

Observatory (SKAO) has announced its selection as the organisation’s next director-general. She is Professor Jessica Dempsey, ...

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.

A NASA satellite that’s been orbiting as space junk since 1967, Relay 2, emitted an unexpected, powerful radio burst that astronomers initially struggled to explain.

To break it down, radio astronomy relies on many different types of antennas and receivers to observe the sky in various resolutions and frequencies. These observations allow astronomers to see ...

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

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.

A NASA satellite that’s been orbiting as space junk since 1967, Relay 2, emitted an unexpected, powerful radio burst that astronomers initially struggled to explain.

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.

Although REACH, which captures radio signals, is still in its calibration stage, it promises to reveal data about the early universe. Meanwhile, the Square Kilometer Array (SKA)—a massive array ...
