Fast Radio Bursts: Mysterious Signals from Space

Fast radio bursts (FRBs) are powerful flashes of radio waves lasting just milliseconds.
They can release as much energy in that instant as the Sun emits in days.
The first FRB was discovered in 2007 in archival telescope data.
Some FRBs repeat, while others appear only once and vanish forever.
Their exact origins remain uncertain, but magnetars are leading candidates.
FRBs travel billions of light-years, carrying clues about the matter they pass through.
They help map intergalactic space by revealing hidden gas and plasma.
Radio telescopes worldwide, like CHIME in Canada, are hunting hundreds of FRBs.
Some early theories even speculated about alien signals—but science points to natural causes.
FRBs are one of the hottest mysteries in astrophysics, with new discoveries every year.
