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 ...

"This is a unique opportunity to learn how the universe's first light emerged from the darkness." ...

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.

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.

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 ...

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 ...

As New Scientist reports, a team of researchers led by Curtin University radio astronomy professor Steven Tingay tracked the signals of almost 2,000 Starlink satellites, with the help of a ...

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

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.
