"Plasma Jets Observed Ejecting From Rapidly Spinning Black Hole"
Another black hole discovery, this time the observations were of a relatively nearby black hole orbiting a star. The black hole is pulling matter off the star and creating powerful jets of plasma as the material is pulled towards the black hole's event horizon. However, the rotation of the black hole appears to be wobbling and so the jets keep being sent off in different directions.
The observations used a number of radio telescopes around the world just like the EHT although in this case it's a different collaboration of scientists and observatories. However, like the EHT, both the JCMT and the SMA on Mauna Kea were involved.

"“The incredible changes in brightness we saw in this JCMT and SMA data, and the model we designed to explain these changes, provided key information needed to develop our imaging method for this paper” Tetarenko said. “Typically, radio telescopes produce a single image from several hours of observation. But these jets were changing so fast that in a four-hour image we just saw a blur. It was like trying to take a picture of a waterfall with a one-second long exposure.”"
