The Chandra X-ray Observatory is a space observatory dedicated to X-ray astronomy. Launched on July 23rd, 1999, this X-ray telescope is particularly dedicated to the observation of high-energy sources in the universe. It has also been used to study the following solar system objects: the Moon, Venus, Mars, Jupiter, and even the Comet C/1999 S4 LINEAR.
Using Chandra, J.-U. Ness and his colleagues detected an unambiguous X-ray emission from the planet Saturn for the first time. A few years ago, a possible such emission was observed using ROSAT, but the present detection is the first certain one.
Ness and his team observed Saturn in April 2003 for about 20 hours. The picture below shows the X-ray image of Saturn that they obtained (in false colour). Each colour (RGB) corresponds to a different energy range of the observed X-rays. Beyond the X-ray detection from Saturn, this Chandra observation allowed the investigators to perform the first in-depth analysis of this emission. The same team also detected X-ray emissions from Saturn using the XMM-Newton Observatory. The observed signal was very similar to what was found with Chandra.

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
