Chandra Space Telescope

ASKAP J1832 belongs to a rare group of objects in space that pulsate in radio waves every few tens of minutes, but what makes it unique is its emission in X-rays as well, as detected by NASA's powerful X-ray observatory, Chandra. This is the first time that X-ray signals have been observed from this type of object, known as "long-period radio phenomena." Credit: X-ray: NASA/CXC/ICRAR, Curtin Univ./Z.

A star called ASKAP J1832 pulsates in both radio and X-rays every 44 minutes—a frequency much slower than any pulsar ever recorded. This unprecedented phenomenon hints at a
