A Deep-Space Echo from the Early Universe Designated FRB 20240304B, the signal belongs to the enigmatic category of fast radio bursts—intense, millisecond-long explosions of energy whose underlying drivers remain a subject of intense scientific debate....

Webb telescope observations have traced the most distant fast radio burst ever recorded to a strange, young dwarf galaxy 3 billion years after the Big Bang. Astronomers have traced a fleeting radio flash to a surprisingly humble origin. Utilizing the...

weigh invisible metal reservoirs in the circumgalactic medium. A team of astrophysicists has used signals from 25 fast radio bursts to peer into the invisible gaseous halo surrounding our home galaxy. The new technique reveals that the Milky Way...

Fast radio bursts flash for mere milliseconds, but these cosmic signals help astronomers map elusive, invisible matter across the vast reaches of space. Astronomers have leveraged a catalog of 114 localized fast radio bursts (FRBs) to map the...

seeks to establish a high-sensitivity station capable of detecting faint cosmic signals, ranging from enigmatic fast radio bursts to potential signatures of extraterrestrial technology. For generations, the far side of the Moon has been considered the...

The Milky Way’s story is written in chemical fingerprints and stellar streams, revealing a complex history of ancient mergers and a future trajectory toward a massive collision with Andromeda. For most of human history, people saw the Milky Way as a...

The Einstein Probe has detected an unusual neutron star merger, revealing an X-ray glow that lasted for nearly 10 minutes, defying previous expectations. A recent observation of a cosmic explosion has provided researchers with a rare glimpse into the...

it could be an alien probe, though this theory remains controversial. In addition, certain radio signals, known as Fast Radio Bursts (FRBs), have been detected from distant galaxies. While these bursts are not yet understood, some speculate that they...

A soft X-ray flare in the galaxy NGC 3783 produced a rare, ultrafast outflow traveling at nearly one-fifth the speed of light, providing an unprecedented look at how supermassive black holes release energy into space. At the heart of the distant galaxy...

Brief flashes of millimeter-wave light seen by the South Pole Telescope reveal magnetic activity in compact white dwarf systems close to the Galactic center, showing that these small stars can release energy in unexpected ways. The center of the Milky...
