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

Ralph Spencer, Professor Emeritus of Radio Astronomy at the University of Manchester in the UK, who was also not involved with the work, agrees that the proposed mechanism is feasible, noting that ...

Fast radio bursts are the brightest radio flashes in the Universe, emitting 30 years’ worth of the Sun’s energy in less than a millisecond – and we only have hints of how they are produced.

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 ...

Astronomer Willice Obonyo describes how scholarship programmes seeded a fresh crop of radioastronomers in Africa.

A mysterious and powerful blast of radio waves detected last year, suspected to originate far beyond the Milky Way came from a long-dead NASA spacecraft in Earth's orbit.

A radio signal from the dawn of time could help scientists weigh the first stars and reveal how they lifted the cosmic darkness.

Watch sunspot region 4114 erupt with its most powerful solar flare yet. The X1.9 class flare triggered radio blackouts across the Pacific Ocean.

Understanding how the universe transitioned from darkness to light with the formation of the first stars and galaxies is a key turning point in the universe's development, known as the Cosmic Dawn ...

An international group of astronomers led by the University of Cambridge have shown that we will be able to learn about the masses of the earliest stars by studying a specific radio signal &ndash ...

The SETI Institute and SpaceX have launched a groundbreaking collaboration to help protect sensitive radio astronomy observations at the Allen Telescope Array (ATA) from interference caused by ...
