Astronomers have discovered a never-before-seen pulsing object in the Milky Way galaxy, located just 15,000 light-years from Earth. The object emits pulses that were detected in both radio waves and X-rays, marking the first time such an object has been detected in X-rays.
The discovery was made by an international team of scientists using a radio telescope in Australia. They correlated the radio signals with X-ray pulses detected by NASA’s Chandra X-ray Observatory. The team found that the pulses occurred in a cycle of two minutes at a time, every 44 minutes.
“This object is unlike anything we have seen before,” said Ziteng Andy Wang, an astronomer who led the research. “We’re still trying to understand its origin and behavior.”
The pulsing object is believed to be either the core of a dead star or a pair of stars in a binary system. However, neither theory fully explains the observations.
“This discovery could indicate a new type of physics or new models of stellar evolution,” Wang added.
The finding provides insights into the existence of long-period transients, which are relatively rare objects that emit radio pulses. The team hopes their findings will shed more light on these mysterious signals and potentially reveal more such objects in the future.
