Their findings are detailed in a study published in April in The Astrophysical Journal, and will help astronomers in their quest to hunt for gravitational waves given off in the universe by objects such as supermassive black holes.
The entire Solar System, including the Sun, has a barycenter, or a common center of mass of all of the Solar System's objects, around which they orbit.
Using these signals, the team of astronomers was able to more accurately measure Earth's distance from other objects in the Solar System, including the barycenter.
Now that astronomers have a more accurate measurement of where the barycenter of the Solar System lies, they can in turn make much more accurate detections of low-frequency gravitational waves
