The radio telescope's image of it was also very fuzzy, which, like with a normal camera, indicated that the source was actually very, very close, not in a distant galaxy, where other FRB signals ...

Astronomers detect 10 billion-year-old radio waves from a distant galaxy cluster SpARCS1049, revealing a mini-halo that suggests black holes or cosmic collisions energize galaxies.

A NASA satellite that had been dead for nearly six decades issued a surprising sign of life. In June 2024, a team of astronomers was perplexed when a radio telescope in Australia scanning the sky ...

NASA satellite emits 'spark' decades after going dormant: Astronomers think they know why Source of the radio waves was tracked to a location that matches that of NASA’s defunct Relay 2 ...

University of Wisconsin-Milwaukee researchers David Kaplan, left, and Akash Anumarlapudi were key members of a global team that made a new discovery in space.

Large radio telescope systems are pivotal instruments in modern astronomy and related fields, as they enable the capture of faint cosmic signals and support various high-resolution observational ...

A team of astronomers has detected a message from the dead. According to a new paper published on arXiv, a burst of transient radio waves that was detected in June 2024 was actually a signal from ...

The largest telescope in the world is called the Gran Telescopio Canarias. It's the biggest optical telescope in the world (radio telescopes can be bigger) and is larger than most houses.

While recent research shows the night sky is getting brighter every year across North America, the Big Bend area in Texas has fended off the light glow that washes out starry nights.
