With the great technological advances in todays world:
I would venture to say that astronomers:
will come across many surprises in the future about not only our solar system but
things far beyond it.

A ring crossing occurs in
-Spring and Fall when the rings are close to being edge on both to the Sun and to us,
so the rings seem to disappear all together.
The next one will occur in 2011.
Why does Saturn have less varied appearance than Jupiter?
The discovery of Silica in the soil and high salt levels suggesting there was once
oceans covering the surface could supply evidence to ward off the idea that there was
never life on mars.
Also, tests for microorganisms in the soil could offer more eviden
Galileo discovered Saturns rings in 1610.
In 1895 astronomers measured theDopplar shift of sunlight reflected from the rings and showed that the velocities thus
determined were exactly what would be expected from separate particles movin

of the moon and Pluto from the Hubble Space Telescope,
-astronomers could determine the mass of Pluto to much greater accuracy than was
The discovery of Charon also permitted astronomers
One theory on this topic is:
that an asteroid from the violent beginnings of the solar system became trapped in
Mars orbit and:
essentially spun fast enough around the planet to churn up its molten core and
power a magnetic field and
- in turn an atmosphe
Instead of being uninteresting:
Miranda displays a wide range of surface terrains, including ridges, valleys, large
oval faults, and other tortuous geological features.
Some researchers have hypothesized that Miranda has been catastrophically
A shepherd satellite is a satellite whose gravitation effect on a ring helps preserve the
Despite the Voyager 1s close pass by Titan, the moons surface remains a mystery
There is a lot of evidence to debate on whether or not life exists or eve
It is thought that the formation of Jupiter and the Galilean satellites mimicked, on a
small scale, in fact the formation of the Sun and the inner planets.
What evidence do we have for liquid water below Europas surface?
Images from Galileo show what look
He discovered Uranus
-while he was charting the faint stars in the sky and came across this odd-looking
It was later realized that this was the seventh planet in the solar system.
It was suspected that there was an eighth planet beyond Uranus beca
