Australian scientists have discovered something unusual Identity Radio from space, one step study It was published last Wednesday in the journal Nature Astronomy.

“Recently, we discovered a radio instability unlike anything astronomers have seen before. And, not only does it have a cycle that lasts almost an hour (The longest ever found), but during many observations we found that it sometimes emits long, bright flashes, sometimes rapid, weak pulses, and sometimes none at all. They commented Authors of the study.

Also, the name of the signal ASKAP J1935+2148. The numbers indicate their location in the sky. The radio transient was discovered using the ASKAP radio telescope, owned by the Australian government agency CSIRO, in the west of the country.

“It belongs to a relatively new class of long-period radio transients. Only two have yet been discovered, and period 53.8 minutes ASKAP J1935+2148 is the longest”; the scientists wrote.

The mystery of the radio signal

Regarding the nature of this signal, similar patterns are observed Neutron stars. However, scientists cannot rule out that it is possible A white dwarfEarth-sized ash that has exhausted the fuel of a burned-out star.

“This material can make us Revise our understanding “Neutron stars or white dwarfs have been known for decades, especially how they emit radio waves and how their population is in our galaxy”; the study authors concluded. Research on this phenomenon is ongoing.
