 In our 2018 review, we covered the shadow cast by a debris ring around the star HBC-672 in the Serpent's Nebula, 1300 light years away. Its nickname was the Bat Shadow. A recent relook at the object showed that the shadow had unexpectedly moved slightly. Astronomers think that the disc of circling gas, dust and rock, might be roughly saddle shaped with an embedded planet with an orbit inclined to the disc's plane. They estimate that this planet would be about the same distance from its star as the Earth is from the Sun. This planet would be the cause of the doubly warped shape of the orbiting disc and the resulting movement in its shadow.
