Scientists have detected a powerful radio signal originating from a galaxy 8 billion light-years away, marking a significant milestone in our understanding of the universe. This discovery not only ...

Instruments flying more than 18 miles (29 kilometers) above Antarctica detected two unexplainable radio pulses coming from below the ice — and these signals seem to defy particle physics. Researchers ...

Associate Professor of Physics Jonathan Pober has spent the past 20 years detecting faint astronomical signals in radio waves that can provide information about the early universe. This task can be ...

Nearly two decades ago, an experiment floating high above Antarctica caught a weird signal. The balloon-borne suite of instruments recorded a similar event in 2014, and scientists have been scratching ...

Understanding how the universe transitioned from darkness to the emergence of stars marks a critical shift known as Cosmic Dawn. Yet, astronomers have struggled to unravel details about the first ...

Are we alone in the universe? Are there other technological civilizations out there and how can we find them? This is what a recent preprint submitted to The Astronomical Journal hopes to address as a ...

Could the first confirmed signal from an extraterrestrial source be less a hello than a goodbye? Astrophysicist David Kipping argues as much, and his “Eschatian Hypothesis” reimagines the way ...

Illustration showing communication between planets beyond our solar system looking from the perspective of Earth. New research using the Allen Telescope Array looked for this type of communication, ...

The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio ...
