ESA's XMM-Newton spacecraft has detected an unprecedented X-ray signal coming from the very edge of a supermassive black hole.
This defies how we thought matter falls into black holes, and points to a potential source of gravitational waves for ESA’s future LISA mission.

TLDR ; Physicists cannot exactly explain x-ray 10% amplitude oscillations at periods from 400s to 1000 s, observed from the surrounding of a black hole, despite some hypothesis including that a white dwarf would be orbiting it at aprox 50% light speed.
@A_A@lemmy.world Thank for for the TLDR
