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." ...

“What we’ve been trying to do is find a baby version of our Solar System somewhere else,” Merel van ’t Hoff, an astronomer at ...

Using the world's most advanced radio telescopes, astronomers have discovered a spinning dead star so rare, strange and ...

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

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.

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 ...

“They’re very rarely perfectly spherical,” says Yvette Cendes, a radio astronomer at the University of Oregon who was not involved in the discovery.

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.

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.

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 ...
