US EditionAstronomers Discover Strange, 'Exotic' Celestial Object in Our Milky Way Galaxy
- Astronomers discovered ASKAP J1832-0911, a celestial object in the Milky Way emitting two-minute radio and X-ray pulses every 44 minutes.
- This discovery builds on identifying long-period radio transients since 2022, with fewer than a dozen known, and the X-ray detection was unexpected and rare.
- Researchers used the ASKAP radio telescope and NASA’s Chandra X-ray Observatory to capture simultaneously timed bursts, but the object's source and emission mechanism remain unclear.
- Lead author Dr. Andy Wang explained that X-rays are typically produced in highly intense and heated conditions, indicating significant activity in the object, while coauthor Dr. Nanda Rea suggested that discovering one such source implies many others may exist.
- The findings imply new physics or stellar evolution models may be needed, and further multiwavelength searches could increase detections and clarify the nature of these exotic objects.

The Search is on for Betel-Buddy
Betelgeuse is dying—but not quietly. This colossal red supergiant, already famous for its brightness fluctuations, has now revealed a strange long-term rhythm: a secondary pulse every 2,100 days. One tantalising theory suggests a hidden companion—possibly a second star orbiting Betelgeuse at roughly the distance between Saturn and the Sun, circling every six years. Astronomers recently pointed the Hubble Space Telescope at the giant in search of…
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…
