Jupiter's Rings Revealed
Explanation: Why does Jupiter have rings?
Jupiter's rings
were discovered in 1979 by the passing
Voyager 1 spacecraft
, but their origin was a mystery.
Data
from the
Galileo spacecraft
that orbited
Jupiter
from
1995 to 2003
later confirmed that these rings were created by
meteoroid impacts
on
small nearby moons
. As a small meteoroid strikes tiny
Adrastea
, for example, it will bore into the moon, vaporize, and explode dirt and dust off into a
Jovian orbit
.
Pictured above
is an
eclipse of the Sun
by Jupiter, as viewed from Galileo. Small dust particles high in
Jupiter's atmosphere
, as well as the
dust particles
that
compose the rings
, can be seen by
reflected sunlight
. Note: Meet

and APOD editor RN in Austin

Tuesday night.
