An international team of astronomers has discovered an unusual object in our galaxy that emits two types of signals exactly every 44 minutes. The full results of the study were published in the journal Nature.
The mysterious celestial body, named ASKAP J1832−091, is located about 15,000 light-years from Earth in a densely star-studded region of the Milky Way. It emits radio waves and X-rays in a regular 44-minute cycle. This is the first known case of such behavior.
The discovery is the result of collaboration between two telescopes: Australia’s ASKAP and NASA’s Chandra X-ray Observatory. Although the object resembles a dead star — such as a neutron star or white dwarf — its characteristics do not match any known type of celestial body. Scientists are considering the possibility that it may represent an entirely new class of objects, known as LPTs (long-period transients), of which only a few have been identified to date.
ASKAP J1832−091 remains active for about a month before falling silent for an extended period. The regularity and nature of its emissions remain a mystery, and potential explanations — ranging from an extremely magnetized binary system to a new type of exotic star — require further study. As the researchers emphasize, this groundbreaking discovery could shed new light on the “afterlife” of stars and the evolution of the galaxy.
