Astronomers 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.

A Mysterious Space Object Is Firing Signals at Earth Every 44 Minutes
Out in the cosmic wilds of our galaxy, some 15,000 light-years from our collective home, astronomers have found something that behaves like a galactic lighthouse. It’s called ASKAP J1832-0911, and…whatever it is, it sends out a pulse or blink or signal, whatever you want to call it, once every 44 minutes like it’s trying to reach out in Morse code, but very slowly. Discovered with Australia’s ASKAP radio telescope, this peculiar beacon emits two…
15,000 light-years away, something unknown pulsates in the rhythm of 44 minutes. Even experienced astronomers face a cosmic mystery.
Scientists Spot Mysterious Object in Our Galaxy Pulsing Every 44 Minutes
Astronomers have spotted something strange and spectacular: a mysterious object that keeps emitting pulses every 44 minutes. In a press release from Australia's Curtin University, which was part of the international team that detected the object just 15,000 light-years away in our Milky Way galaxy, astronomers explained that the find was all the more stunning because the signal is coming in the form of both X-rays and radio waves. The object, wh…
Weird Signals from Space Are ‘Unlike Any Known Galactic Object’
Welcome back to the Abstract! This week, scientists accidentally discovered a weird thing in space that is like nothing we have ever seen before. This happens a lot, yet never seems to get old. Then, a shark banquet, the Ladies Anuran Choir, and yet another reason to side-eye shiftwork. Last, a story about the importance of finishing touches for all life on Earth (and elsewhere).Dead Stars Still Get HypedWang, Ziteng et al. “Detection of X-ray e…
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…
