Astronomers have detected fast-repeating radio bursts from a distant "dead" galaxy that should not contain the energy to produce these types of signals, according to new research. The source of the ...

Giant radio galaxies are cosmic megastructures that can span millions of light-years, making them some of the largest-known structures in the Universe. Yet space is big, and despite their size, giant ...

With their extremely strong magnetic fields, magnetars have long been considered the prime culprit capable of producing the powerful bursts of energy known as fast radio bursts. The recent burst, ...

These clouds of radio energy are "radio relics" resulting from powerful shockwaves surging through the hot gas that fills the space amid a galaxy cluster. Credit ...

Astronomers studying a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of the early universe. While studying the distant galaxy cluster known as ...
