A disc of yellow, orange, and brown gasses with a blue and purple exterior and a blue cone in the center that sticks out both sides spins on a tilted axis in space. It glows bright white and emits gasses above and below it. The cones in the center fade, then reappear.
 
Text, A distant galaxy became 100 times brighter in visible light, while its high-energy X-rays temporarily disappeared. Why? Astronomers think the magnetic poles of the galaxy's black hole flipped, which is not uncommon in nature. The Sun's poles flip about every 11 years.
 
A diagram with the bright disc at the center. Curved lines in yellow run through the center with arrows that point up. The top is labeled North and the bottom South. The disc flares brightly and curved lines in orange begin to run through the sides with arrows that point down. The yellow lines disappear the top is labeled South, the bottom North.
 
Text, As the flip began at the edges of the dusty disk surrounding the black hole, material fell inward and caused the increased brightness. As the flip progressed inward, the magnetic field weakened, causing the high-energy X-rays surrounding the black hole to vanish. Four months later the high-energy X-rays were detected again, indicating the galaxy was back to normal, but now with its poles fully reversed.
 
The galaxy as a disc gasses with a blue cone in the center that sticks out both sides. The cones are labeled high-energy X-rays.
