The article says "The telescope at the observatory was equipped with a camera that would take two photographs of the sky on different days. A device known as a blink compactor rapidly flipped back and forth between the two photographs. Stars and galaxies essentially remained unmoving in the images, but anything closer could be visually identified by its motion across the sky."

The device isn't called a blink compactor, it's called a blink comparator. https://en.wikipedia.org/wiki/Blink_comparator

But we are NEVER at the same point every day.
