the Galilean satellites. From
top to bottom, the moons
shown are Io, Europa,
Ganymede and Callisto.
The Great Red Spot, a

Jupiter in just under 2 days, but it
is Europa that will probably receive
the most attention because it has
oceans under a thin surface of ice,

same as Galileo did. Ask the telescope to take images of Jupiter for a
few days and you too will see these
tiny spots of light move around the
planet. Check exactly how to do it
by finding images in the image gallery. With a bit of care and by using
different exposures, you should also
be able to see the Great Red Spot
on Jupiter: a giant storm that has
been raging for at least 400 years
and which is big enough to engulf
the Earth. The moons themselves
are uniquely interesting; Io, the
moon nearest Jupiter, is the most
With multiple requests to the telescope, you will be able to measure
the orbital time of the moons of
