Oceans were long thought to exist in all corners of the Solar
System, from carbonated seas percolating beneath the clouds of
Venus to features on the Moon's surface given names such as "the
Bay of Rainbows" and the "Ocean of Storms." With the advent of
modern telescopes and spacecraft exploration these ancient concepts
of planetary seas have, for the most part, evaporated. But they
have been replaced by the reality of something even more exotic.
For example, although it is still uncertain whether Mars ever had
actual oceans, it now seems that a web of waterways did indeed at
one time spread across its surface. The "water" in many places in
our Solar System is a poisoned brew mixed with ammonia or methane.
Even that found on Jupiter's watery satellite Europa is believed
similar to battery acid. Beyond the Galilean satellites may lie
even more "alien oceans." Saturn's planet-sized moon Titan seems to
be subject to methane or ethane rainfall. This creates methane
pools that, in turn, become vast lakes and, perhaps, seasonal
oceans. Titan has other seas in a sense, as large shifting areas of
sand covering vast plains have been discovered. Mars also has these
sand seas, and Venus may as well, along with oceans of frozen lava.
Do super-chilled concoctions of ammonia, liquid nitrogen, and water
percolate beneath the surfaces of Enceladus and Triton? For now we
can only guess at the possibilities. 'Alien Seas' serves up part
history, part current research, and part theory as it offers a rich
buffet of "seas" on other worlds. It is organized by location and
by the material of which various oceans consist, with guest authors
penning specific chapters. Each chapter features new original art
depicting alien seas, as well as the latest ground-based and
spacecraft images. Original diagrams presents details of planetary
oceans and related processes.
