New TNO finded on Hubble archive images

Astronomers from Harvard-Smithsonian Center for Astrophysics, using clever techniques to cull the data archives of Hubble Space Telescope have added 14 new Trans-Neptunian objects to the catalog. Their method promises to turn up hundreds more. The team developed software to analyze hundreds of Hubble images hunting for such streaks. After promising candidates were flagged, the images were visually examined to confirm or refute each discovery. Most TNOs are located near the ecliptic — a line in the sky marking the plane of the solar system (since the solar system formed from a disk of material). Therefore, the team searched within 5 degrees of the ecliptic to increase their chance of success. They found 14 objects, including one binary. All were very faint, with most
measuring magnitude 25m-27m.  The newfound TNOs range from 25 to 60 miles (40-100 km) across. Perhaps this is the most smallest TNO objects, discovered at this time.
