This is thousands of times longer than the length of the repeated variations seen in\u00a0pulsars, which are rapidly spinning neutron stars that have repeated variations multiple times a second. ASKAP J1832 cycles in radio wave intensity every 44 minutes, placing it into this category of long period radio transients. Using Chandra, the team discovered that ASKAP J1832 is also regularly varying in\u00a0X-rays\u00a0every 44 minutes. This is the first time that such an X-ray signal has been found in a long period radio transient.<\/p>\n<p><em>Image credit: X-ray: NASA\/CXC\/ICRAR, Curtin Univ.\/Z.
