Astronomers spotted 139 new objects in our solar system in orbit beyond Neptune.
Many of these new trans-Neptunian objects reside in the same area of our system that Pluto does, but some are much further away from the Sun.
The new discoveries make up 10 percent of confirmed trans-Neptunian objects on record.

A massive treasure trove of newly-discovered solar system objects was just revealed by astronomers in a new research paper published in The Astrophysical Journal Supplement Series. The team of researchers from the University of Pennsylvania made their discoveries using observations from the Dark Energy Survey, or DES, a six-year project that led to the detection of over 300 objects lurking beyond Neptune.

Of those hundreds of detected objects, 139 of them are new to science. The data that the team had to comb through included millions of possible objects that were detected during the survey. By cross-referencing scans and cataloging the objects that wee consistently observable, the team was able to determine which parts of the data revealed actual trans-Neptunian objects, or TNOs.
