US EditionAstronomers Detect Milky Way Object Pulsing in Radio and X-Rays Every 44 Minutes
- Astronomers discovered a strange object named ASKAP J1832-091 in the Milky Way emitting radio and X-ray pulses every 44 minutes during intense activity periods.
- The object was detected by chance last year by NASA's Chandra X-ray Observatory while observing a supernova remnant about 15,000 light-years away in a star-filled region.
- Lead author Ziteng Andy Wang noted that the emission pattern is unlike any previously observed in long-period radio transients—a rare type of object that emits radio signals over intervals of tens of minutes—and suggested the source may be an extremely magnetized compact remnant, such as a neutron star or white dwarf, or possibly an unknown and exotic phenomenon.
- Wang explained that the findings either reveal a completely new phenomenon or indicate a familiar kind of celestial source producing both radio and X-ray emissions in a manner not previously detected.
- Scientists noted more such objects may exist, and while the discovery deepens the mystery, studying them advances understanding of cosmic phenomena emitting synchronized radio and X-ray signals.

Scientists Are Stumped by Mysterious Pulsing 'Star'
Something strange is going on 15,000 light years from Earth. Out at that distant remove, somewhere in the constellation Scutum, an unexplained body is semaphoring into space, blinking in both X-ray and radio frequencies once every 44 minutes in a way never seen by astronomers before. The object could be a white dwarf—an Earth-sized husk that remains after a star has exhausted its nuclear fuel. Or not. It could also be a magnetar—a neutron star w…
Astronomers Detect Repeated Signals From a Space Object “Different From Everything We Have Seen Before”
Astronomers, using radio telescopes, have long been detecting sporadic bursts of radio waves originating in the vast expanse of the Universe. They have been called “radio transitories”: some erupt only once and never again, and others are turned on and off following predictable patterns. Astronomers believe that most transient radio stars come from rotating neutron stars known as pulsars, which emit regular flashes of radio waves, such as cosmic…
Something in Deep Space is flashing every 44 minutes and Astronomers have no idea what it is
In the vast expanse of the Milky Way, 15,000 light-years from Earth, a celestial mystery is captivating astronomers. According to Study Finds, an object, designated ASKAP J1832-0911, emits pulses of radio waves and X-rays every 44 minutes, a rhythm that defies current understanding of cosmic phenomena. Discovered by an international team led by Dr. Ziteng […]
