In the hunt for Planet Nine, astronomers are looking at a new search technique for the elusive world

Finder Planet Nine may require looking at telescopic images in a different light. Astronomers proclaim a “shifting and stacking” technique that could help the hunt for the supposed world, as some scientists believe lurking undetected in the outer systemfar beyond Pluto’s orbit. The strategy involves shifting space telescope images along sets of possible orbital paths and then stacking photos together …
