Plot of All Known Kuiper Belt Objects, Set Against the Four Outer Planets

This is an artist's view of a Kuiper Belt binary object, called 1998 WW31. These icy bodies orbit each other at the fringe of our solar system. The illustration depicts one member of the duo in the foreground; its companion - the dark,...

This is an artist's impression of a small Kuiper Belt Object (KBO) occulting a star. NASA/ESA Hubble Space Telescope recorded this brief event and allowed astronomers to determine that the KBO was only about 800 metres across, setting a...

This is an artist's impression of a Kuiper Belt Object (KBO) 800 metres in diameter, that was detected by the NASA/ESA Hubble Space Telescope. The icy relic from the early Solar System is too small for Hubble to photograph. The object...

An image of the Kuiper belt.

This illustration shows that the Kuiper Belt is shaped like a disk [see inset diagram] and resides within the shell-like structure of the Oort Cloud. Located on the outskirts of the solar system, the Kuiper Belt is a "junkyard" of...

This site provides a historical look at the Kuiper Belt; its theoretical prediction, finding, and the man behind it all - Gerald Kuiper.

Wikipedia, a publicly-maintained encyclopedia, provides an article on the dwarf planet, Pluto, including images, physical characteristics, history of its naming, the planet/dwarf planet debate, and more.

This image shows the globular cluster M22 as seen with the NASA/ESA Hubble Space Telescope's workhorse instrument, the Wide Field and Planetary Camera 2 (WFPC2). A team of American and European astronomers has studied the cluster in...

Galaxies can take many forms - elliptical blobs, swirling spiral arms, bulges, and discs are all known components of the wide range of galaxies we have observed using telescopes like the NASA/ESA Hubble Space Telescope. However, some of...
