KBOsThese two multiple-exposure images from the Hubble Space Telescope show Kuiper Belt objects or (KBOs) moving against a background of stars in the constellation Sagittarius. The two KBOs are roughly 4 billion miles from Earth. The Kuiper belt is a debris field of icy bodies left over from the solar system’s formation 4.6 billion years ago.

Hubble has been given the go-ahead to conduct an intensive search for a suitable outer solar system object that the New Horizons spacecraft could visit after the probe streaks though the Pluto system in July 2015.
