Astronomers in Australia have detected a mysterious cosmic object, named ASKAP J1832-0911, that sends out bursts of radio and X-ray signals every 44 minutes, an occurrence unlike anything previously observed. The discovery was made using the Australian Square Kilometre Array Pathfinder (ASKAP) and NASA’s powerful Chandra X-ray Observatory. The signals last for about two minutes and reappear at consistent intervals, leaving scientists puzzled. This rare behaviour classifies the object as a long-period transient (LPT), a phenomenon not well understood. The discovery raises new questions about the evolution of dead stars and the possibilities of unknown space physics.
How does the mysterious object ASKAP behave
ASKAP J1832-0911 doesn’t behave like any known star or pulsar. While typical pulsars emit rapid pulses lasting milliseconds or seconds, this object produces signals at much longer and consistent intervals. It “switches on” and “switches off” every 44 minutes, a rhythmic pattern that puzzles scientists. This behaviour defies existing theories of stellar remnants, which generally operate on much shorter timescales. The precise timing and strength of these signals suggest a mechanism we have yet to fully understand. With no known counterparts in current astrophysical databases, this object may represent a new class of transient phenomena in deep space.
Possible explanations of sending signals every 44 minutes
Scientists suggest that ASKAP J1832-0911 could be a type of magnetar, a highly magnetic remnant of a dead star, or a binary system involving a white dwarf. However, none of these theories fully explain the signal pattern. The regularity and intensity of the pulses point toward unknown or poorly understood physics, sparking interest in developing new models.

What aspect of ASKAP J1832-0911 intrigues you the most?
The role of cutting-edge observatories
The Australian Square Kilometre Array Pathfinder and NASA’s Chandra X-ray Observatory played a key role in this discovery. ASKAP detected the radio pulses, while Chandra confirmed X-ray emissions from the same source. This multi-wavelength approach provided the necessary evidence to classify the object and rule out common causes like interference or background noise.
What makes this discovery important
This may be the first indication of a new class of celestial bodies. Long-period transients are extremely rare, and this one could reshape how we understand stellar remnants and high-energy cosmic events. It also highlights the importance of continuous sky monitoring to catch such unusual phenomena in action.
Next steps in the investigation
Astronomers plan to search for similar signals across the sky using the same observatories. Identifying more objects like ASKAP J1832-0911 could confirm whether it is truly unique or part of a hidden population. Future observations may also uncover details about its origin, energy source, and possible implications for space science.
