Star-sized "comets" seen orbiting supermassive blackhole

"Comets" Found Orbiting Monster Black Hole
"The clouds orbit the black hole at roughly ten thousand times the
distance between Earth and the sun, the team found.

The "head" of each cloud is about the size of sun, the scientists say,
while the cometary tails stretch more than 93 million miles (150
million kilometers)."
