[edit] Astrochemistry
Astrochemistry is a relatively new domain of chemistry but is very important because it helps us to know how the Universe was made.
We know that all the Universe is made of materia and chemical elements. All the elements have an age. For example Lead was born from the transformation of Uranium 4.6 milliarde years ago. Let's talk about stars! Our Sun is also a "chemistry object". We know that the stars are made of Hydrogen which is permanently transformed into Helium so that the stars became big "plasma balls" -- Plasma being the 4th state of aggregation after solid, liquid, and gas.
A recent article, "Milky Way Fortified with Calcium" by Sara Goudarzi, February, 2007 discloses that our Galaxy, the Milky Way, "is fortified with Calcium".
