A mysterious cosmic object is sending pulses of radio and X-ray waves to Earth every 44 minutes, leaving astronomers baffled and eager for answers.

Researchers traced long, bright radio pulses, combined with X-rays, to an intriguing cosmic object 15,000 light-years from Earth, according to a new study.

The mystery object, located just a short 15,000 light-years from Earth in our Milky Way galaxy, was spotted emitting unusual pulses.

The mystery surrounding a strange cosmic object, or 'long-period transient,' has deepened. This object is bursting with X-rays, and astronomers describe it as unlike anything seen before.

With the aid of citizen scientists, astronomers have discovered an erupting cataclysmic variable star in a rarely seen evolutionary stage.
