Titan Could Help the Study of Oceanography.

According to researcher Ralph Lorenz, Saturn's Moon Titan could help teach scientists about how oceans and weather work on the Earth. Titan is thought to have oceans of liquid methane, but they are created under a completely different environment from our own familiar oceans. When Cassini and the Huygens probe arrive at the Saturn system in 2004, they will begin gathering data about Titan and its oceans and weather, and help answer questions like: how deep are its oceans? do they form steep cliffs or shallow beaches? and what effect does Saturn's huge gravity have?

Spirit's Next Target, "White Boat".

This is a composite red-green-blue image of the rock called White Boat. It is the first rock target that Spirit drove to after finishing a series of investigations on the rock Adirondack. White Boat stood out to scientists due to its light color and more tabular shape compared to the dark, rounded rocks that surround it.

Why is Mars So Dry?

Since Earth and Mars were probably formed much the same way; through the accretion of rocky material from the inner solar system, they should have roughly the same amount of water, but Mars is pretty much bone dry compared to the Earth. So what happened to make it so dry? Some scientists believe that Mars used to have the same amount of water as Earth, but it evaporated into space. Others believe that the Red planet never had much water in the first place; that it started out as a collection of dry materials from the asteroid belt.

Rosetta Launch on board an Ariane 5 rocket

The European Space Agency's Rosetta spacecraft is all set to launch on board an Ariane 5 rocket on February 26, 2004. The spacecraft will meet up with Comet 67P/Churyumov-Gerasimenko in 2014, and then journey alongside it to see how comets change as they fly towards the Sun. It will deposit a lander onto the surface of the comet, which will use a two-metre arm to investigate its surroundings.

Galaxy Beats Distance Record.

An international team of Astronomers have found what could be the most distant Galaxy ever discovered. Located 13 billion light-years away, it's being seen when the universe was only 750 million years old. The object was found by combining the power of the Hubble Space Telescope and the W.M. Keck telescope; they also used the natural gravitational lensing effect of a relatively nearby galaxy, which focused the light of the more distant galaxy. This Galaxy is small - only 2,000 light-years across - but it's forming stars at a furious rate.
