This is an artist&#39;s rendering of the New Horizons spacecraft encountering a Kuiper Belt object &#8212; a city-sized icy relic left over from the birth of our solar system. The sun, more than 4.1 billion miles (6.7 billion kilometers) away, shines as a bright star embedded in the glow of the zodiacal dust cloud. Jupiter and Neptune are visible as orange and blue &quot;stars&quot; to the right of the sun.
