Astronomers discovered a mysterious 2-hour radio pulse from a hidden white dwarf system, revealing a new type of stellar duo and reshaping our understanding of space signals.

In the past three years, astronomers have discovered a mysterious new type of radio source. We call these long-period transients.

Scientists have captured a special kind of radio signal from a galaxy that’s nearly 9 billion light-years away from the Earth. The signal was not sent by aliens but was emitted from a star-forming galaxy called ‘SDSSJ0826+5630’, when the universe was only 4.9 billion years old.

Astronomers have finally traced mysterious radio pulses in the Milky Way to a unique cosmic duo—a red dwarf and a white dwarf orbiting each other every two hours. This discovery challenges previous assumptions that only neutron stars produce such signals.

Astronomers have traced a starnge blast of radiowaves that repeats every 2 hours back to a dead star white dwarf magnetically slamming its stellar companion.
