We just caught a black hole shooting matter out in two different directions at the exact same time.

The Takeaway
Black hole jets are usually expected to be perfectly aligned like a cosmic lighthouse beam, but this one is spitting out continuous streams in one direction and 'bullets' of matter in another. This discovery suggests the black hole's entire engine is warped and wobbling like a spinning top, defying current formation models.
From the abstract
We report a large misalignment between the continuous jet and the discrete ejecta in GRS 1915+105, detected in April 2023 with the East Asian VLBI network (EAVN). Two-sided ejecta are shown at 6.7 GHz images and central continuous jets are resolved at 43 GHz by EAVN quasi-simultaneously. While the continuous jet was aligned with the long-standing jet position angle (PA) of about 147 degree, the discrete ejecta appeared at a markedly different PA about 188 degree, with the lowest intrinsic veloci
