Astronomers say new celestial object in our Milky Way galaxy producing radio waves

简介：

Astronomers have discovered a mysterious object in the Milky Way that emits X-rays and radio waves in a repeating 44‑minute cycle during periods of intense activity. Located 15,000 light‑years away in a star‑rich region, the object—dubbed ASKAP J1832−091—could be a highly magnetized neutron or white dwarf star, or possibly something entirely new. Spotted by NASA’s Chandra X‑ray Observatory while observing a supernova remnant, this marks the first detection of X‑rays from a rare long‑period radio transient, KSL.com has reported. Its hyperactive phase lasted about a month, raising the possibility of more such objects yet to be discovered.
