US Edition'Unlike anything we have seen before': Astronomers discover mysterious object firing strange signals at Earth every 44 minutes
- In 2023-2024, an international team of astronomers identified a mysterious object in the Milky Way called ASKAP J1832-0911 that emits bursts of radio waves and X-rays lasting two minutes each, occurring every 44 minutes.
- Astronomers first detected this long-period transient class of objects in 2022 and confirmed X-ray emissions from ASKAP J1832-0911 by chance in 2024 during Chandra's observation of a nearby supernova remnant.
- ASKAP J1832-0911’s simultaneous radio and X-ray signals challenge existing classifications, as neither magnetars nor white dwarf binaries fully explain its bright, variable emissions.
- Dr. Andy Wang, the lead author, described the discovery as unprecedented, highlighting that the detected X-rays indicate highly energetic processes and that the finding resulted from a rare, coordinated global collaboration.
- This discovery may indicate new physics or stellar evolution models, with scientists expecting further observations to uncover more such objects and better understand their mysterious nature.

Astronomers Detect Repeating Signals From Space Object That's "Unlike Anything We Have Seen Before”
An international team of astronomers has detected a mysterious object in deep space that regularly sends out two-minute pulses of radio waves and X-rays in a repeating pattern every 44 minutes. Known as ASKAP J1832- 0911, the mysterious object has left researchers stumped due to its unusual combination of radio waves and X-rays and its propensity to ‘switch on’ and ‘switch off’ at such regular and coordinated intervals. “This object is unlike an…
Astronomers discover strange, 'exotic' celestial object in our Milky Way galaxy
Astronomers have discovered a strange new object in our Milky Way galaxy.An international team reported Wednesday that this celestial object perhaps a star, pair of stars or something else entirely is emitting X-rays around the same time it's shooting out radio waves. What's more, the cycle repeats every 44 minutes, at least during periods of extreme activity.Located 15,000 light-years away in a region of the Milky Way brimming with stars, gas a…
